Forged carbon, alloy and tool steels are used for applications in just about every industry. Carbon steel is generally the lowest cost option for steel. Many grades of carbon steels are hardenable through heat treatment that includes quenching and tempering steps; however, the super high strength of stainless steels cannot be achieved with carbon steels.
Carbon steel grades are commonly used for applications that don’t require high strength or operate in high temperature environments. The hardenability of carbon steels is limited because only carbon is used for the purpose.
Alloy Steel makes use of additional alloying elements for increased hardenability and improved properties. Manganese, chromium, nickel and molybdenum are some of the elements used for increased strength, toughness and wear resistance compared to carbon steel. Other desirable characteristics such as corrosion resistance, strength at elevated temperature and creep resistance are also achieved through alloying element additions.
Tool steel is a combination of selected alloy steel and carbon steel grades and its characteristic high hardness and abrasion resistance make it ideal for cutting and machining various types of metals. Major alloying elements in tool steel are chromium, molybdenum, vanadium and tungsten. These carbide formers allow tool steel to resist deformation and maintain a sharp cutting edge at high temperatures.
Scot Forge holds an inventory of various grades for customers to order for their carbon alloy and tool steel forging needs and specifications:
With carbon steel, there are 4 main grades: low carbon steel, medium carbon steel, high carbon steel, and very high carbon steel.
Low Carbon Steel
Low carbon steel has 0.05% to 0.25% carbon which allows the material to be ductile. Low carbon steel is a low cost option for applications where high strength is not a consideration.
Medium Carbon Steel
Medium carbon steel has 0.29% to 0.54% carbon which contains a higher amount of manganese and allows the material to be quenched and tempered after forging. These forgings offer higher strength and toughness than low carbon steels, yet avoid the higher costs associated with the highly alloyed stainless steels.
High and Very High Carbon Steel
High and very high carbon steel has 0.55% to 2.1% carbon which allows the material to achieve high hardness and resilience.
Carbon steel hardened by heat treatment has increased strength and toughness. Tool steels, containing higher amounts of carbon, are normally forged for the purpose of creating tools that can resist abrasion, fatigue and wear.
Below is a list of the benefits of using forged carbon, alloy and tool steel:
Our capabilities include eight hydraulic open die presses, four ring mills, six pneumatic hammers, one bar planishing mill and one hydraulic upset press. Scot Forge can produce parts that weigh from 1 lb. to 300,000 lbs. in aluminum materials. Below is a list of our skills for carbon alloy and tool steel forging:
In addition, we provide value-added processes such as saw cutting, heat treating, contour torch cutting, destructive testing, metallurgical analysis and Level III nondestructive testing for all carbon alloy and tool steel forging.
Scot Forge is proud to be ISO 9001:2015 certified as well as AS9100D and committed to providing outstanding customer satisfaction. Further pursuance of aerospace products has led to NADCAP accreditation in both Heat Treatment for carbon alloy and tool steel material and Nondestructive Testing. By developing a personal relationship with Scot Forge, each customer is valued and placed with a qualified team that will see through each carbon alloy and tool steel forging delivered from inquiry stage to order placement, expediting and shipping.
