FORGED PRODUCTS FORGE CONSULTATION SERVICES FORGED PRODUCTS FORGE CONSULTATION SERVICES Closed-Die Alternative Case study Hybrid Forging Compared To Castings & Fabrications Forging delivers significant economic, manufacturing and quality advantages, such as directional strength, structural strength and impact strength compared to alternative metalworking processes. Directional Strength Forging produces predictable and uniform grain size and flow characteristics by mechanically deforming the heated metal under tightly controlled conditions. Forging stock is also typically pre-worked to refine the dendritic structure of the ingot and remove porosity. These qualities translate into superior metallurgical and mechanical qualities and deliver increased directional toughness in the final part. Structural Strength Forging also provides a degree of structural integrity unmatched by other metalworking processes. Forging eliminates internal voids and gas pockets that can weaken metal parts. By dispersing segregation of alloys or non-metallic, forging provides superior chemical uniformity. Simulation & Modeling Reduce Risk, Time & Costs Collaborating closely with customers, the team runs sophisticated simulation and modeling software to tailor a forging process that optimizes time/cost savings. This software also allows for process validation prior to actual manufacturing, reducing risk and ensuring the success of each project.

WE'VE GOT YOU COVERED! FORGING SUCCESS STORIES Forge Industry Terms A B C D E F G H I J K L M N O P Q R S T U V W X Y Z A Alloy Steel Steel that, in addition to carbon, contains one or more elements in sufficient amounts to appreciably alter properties compared with those of carbon steel. Materials are alloyed to enhance physical and mechanical properties such as strength, ductility, and hardenability. Annealing A heat treating operation wherein metal is heated to a temperature above its critical range, held at that temperature long enough to allow full recrystallization, then slowly cooled through the critical range. Annealing removes working strains, reduces hardness, and increases ductility. Austenitic Steels Steels containing such proportion of an alloying element or elements that the austenitic structure is retained at room temperature. B Billet Also often called a bloom. A semifinished product of square, rectangular, or even round cross-section, hot rolled or forged. Producing billets or blooms from ingots by forging is called cogging, while by rolling it is called blooming. Blank A disc-type forging is produced by upsetting and rounding starting stock. Boring Machining a hole or enlarging an existing one with the objective of producing a more accurate hole than by drilling. Bottom Poured Ingot An ingot is produced by pouring molten steel into a vertical trumpet where the steel flows down the trumpet, through runners, and then enters the ingot mold from the bottom. This method provides substantially improved surface quality and internal soundness, as well as ingot yield advantages, over top-poured ingots. Brinell Hardness A measurement of a metal hardness (or ability to resist penetration). A steel ball is forced into the surface of the material tested under a specific load. The diameter of the depression is measured, and the hardness is the ratio of load to spherical area of the impression. C Camel Back A rectangular step-down bar that has the high point near the center. Carbon Steel Steel that owes its properties chiefly to various percentages of carbon with only residual amounts of alloying elements (except those added for composition control such as silicon and manganese). Casting Process of pouring molten metal into a prepared mold cavity of a desired shape and allowing the metal to solidify. Centrifugal Casting Casting process that consists of pouring molten metal into the cavity of a rotating mold, which can be made of various materials. Charpy Impact Test An impact test in which a specially V-notched specimen is broken by the impact of a falling pendulum. The energy absorbed in fracture is a measure of the impact strength or notch toughness of the sample. Closed-Die Forging Also called Impression Die Forging. A forging that is formed to the required shape and size by machined impressions in specially prepared dies that exert three-dimensional control on the workpiece. Cogging The reducing operation in working the ingots into a billet or bloom by the use of forging hammer or a forging press. Concentric Objects or part features having a common center. Contour Torch Cutting Torch cutting or flame cutting a part to achieve a specific shape or contour. D Die A forging die is a steel block with a flat or contoured working face, which is used in a hammer or press for shaping metal. Ductility The property of a metal that enables it to stretch before rupturing. Dumbbell A step down forging with two heads. E Eccentric A step down forging where the journals do not share the same center with the head. Electrical Conductivity The rate at which electrons move through atoms causing current to flow. Elongation The amount of permanent stretch in a tensile test specimen before rupture. ESOP Employee Stock Ownership Plan describes the employee ownership of a company.

Flat Bar A forged bar with a rectangular cross-section and the four corners are at right angles (90°). Flat Head Spindle A spindle with a rectangular head(s). Forging Process of working metal to the desired shape by impact or pressure from hammers, presses or forging machines. The metal object so produced is termed a forging. Flanged (hollow) A hollow forging with one or more protruding ribs or flanges on the outside diameter. G Gear Weldment A semi-finished gear fabrication including the outer ring, inner hub, and torch-cut stiffening plates. Grain Size The average size of the crystals or grains in a metal as measured against an accepted standard. H Hammer Forging The mechanical forming of metal by means of a hammer. The action of the hammer is that of an instantaneous application of pressure in the form of a sudden blow. Hardness The ability of a metal to resist penetration, is defined in terms of the measurement (Brinell, Rockwell, etc.). Hardness Test A test used to determine the relative resistance to indentation or displacement of metals by pressure, or by resistance to abrasion. Common methods of testing include Brinell, Rockwell, and Vickers tests. Head Largest point of a forging. Heat Treatment An operation or combination of operations involving the heating and cooling of a metal or alloy in the solid state to attain certain desired microstructure or properties. Hollow Forging The process of producing circular hollow, tube-like parts by expanding or lengthening the hot workpiece over a mandrel. Hub Part that has been upset forged using loose tools. This process produces a shape with a smaller diameter projection from either one or both sides of the major diameter of the part. I Ingot A casting suitable for working or remelting; the basic starting stock for the forging process. Intergranular Corrosion Corrosion of a metal along its grain boundaries. ISO 9001 An international family of specifications and standards for quality assurance management systems involving a third party for inspection and registration.

Metallographic Examination Study of the microscopic features of material surfaces that have been specially prepared by cutting, grinding, polishing, and etching. Metallurgical Science of metals and alloys devoted to the study of engineering materials. Microhardness Testing Testing technique used for measuring the hardness of the constituents in the microstructure of a metal. Milling The process of producing machined surfaces by progressively removing a predetermined amount of material from the work piece which is fed to a rotating milling cutter. N Neck Transition point when going from one size to another in a forging. Necking Refers to the operation of cutting a groove of predetermined depth in a work piece. Nondestructive Testing Any type of testing performed on an object that leaves it unchanged. Non-ferrous Metals that do not contain iron as the major alloying element. Normalizing Commonly used heat treatment that decreases pearlite interlamellar spacing and refines grain size. The process consists of heating steels above the transformation temperature range, holding at temperature, and then cooling in air. O Open Die Forging The mechanical forming of metals between flat or shaped dies, where flow of the metal is not completely restricted. Open Die Press, Hydraulic A forging press with a hydraulically operated ram. P Peeled Bar A round bar that has been centerless machined to remove its outer surface. The peeling process takes less than one-fourth the time of conventional lathe-turning operations. Planishing A finishing operation used to obtain closer tolerances and a smoother surface on a round workpiece. Planishing Mill, Bar A custom-designed, computer controlled GFM single-stand bar mill. After an initial forging process, bars are sent through a series of reversing passes on the planishing mill where they are rolled to a smooth surface in less than five minutes. Pneumatic Hammer A forging hammer that uses compressed air both to drive the hammer down for a working blow to the workpiece and reposition it for the next blow. Press Forging Mechanical forming of metals by means of a press. The action is that of kneading the metal by relatively slow application of force as compared with the action of hammering. Profiled Rolled Ring A forged rolled ring with a contoured or profiled cross section achieved during the rolling process. Q Quenching Rapid cooling of a heated metal, generally by immersion in liquids, to increase strength and hardness. Quenching is always followed by a temper to increase ductility. R Ring Mill Equipment used to produce forged rolled rings. A metal ring preform is rolled between two rolls that move toward each other to form a continuously reducing gap. Ring Preform Material that has been upset and pierced to form a hollow "donut." This is the starting stock needed to produce a rolled ring. Rolled Ring A forged seamless ring produced on a ring mill. Rough Machining A machining operation that allows stock for subsequent finish machining. S Saw Cutting Metalworking process used to cut starting ingot or billet stock to length in preparation for the forging process and also to trim forged parts to size. Scale Oxidation that forms on the outside of hot metal and forms a crust. The appearance and amount of scale is depended on the grade of steel and the time it is in the furnace before processing. Secondary Processing As used in this reference, all metalworking processes that follow the forging process. Typical secondary processes are heat treating, rough machining, trimming, torch cutting, and testing. Shot Blasting A metal cleaning or finishing process in which a fluid blast blows abrasive steel balls against the surface. Spectrochemical Analysis Test performed to verify a material chemistry Spindle Also referred to as a stepdown shaft. A longitudinal bar-type product with more than one diameter or cross section size. Square Bars A forging that has four equal sides and the four corners are at right angles (90°). Step-down Shaft Also referred to as a spindle. A longitudinal bar-type product with more than one diameter or cross section size. Stock Stock is the amount of additional material above the rough turn print sizes. The more stock, the greater the chance the work piece will still be acceptable even with surface defects in present. T Tartan Bars® Round bars 6" to 16" diameter with a forged center and rolled bar surface produced only by Scot Forge. Thermocouple A device consisting of two different conductors (usually metal alloys, termed “bi-metallic”) that produce a voltage proportional to a temperature difference, between either end of the two conductors. Thermocouples are a widely used type of temperature sensor for measurement and control. Temper Heat treat process performed after quenching or normalizing. The forging is heated to a temperature below the critical temperatures and cooled at a suitable rate. Tempering steel after hardening to relieve quenching stresses ensures dimensional stability and obtains specified mechanical properties. Tensile Strength The maximum load per unit of initial cross-sectional area obtained before rupture in a tension test. Tensile Test A tension-testing machine mechanically or hydraulically applies a tensile load to a specimen. The test establishes ultimate strength, yield strength, and ductility (elongation and reduction of area). Torch Cutting The cutting or parting of steel objects with a torch using a flame with excess oxygen to completely oxidize or "burn" the steel directly in the path of the flame; flame cutting. Toughness Testing Test used to assess the resistance of metals to brittle fracture propagation (spreading) in the presence of stress raisers.
