Forged Stainless Steel Advantages

Forged stainless steel is popularly used in a variety of industries, such as industrial, food, infrastructure and oil & gas due to its ability to perform in high stress and corrosive environments. Parts that can be manufactured using stainless steel forging include:

  • Turbine shafts
  • Rotor shafts
  • Structural components for cryogenic vessels
  • Nuclear waste container vessels
  • High strength parts for salt water environments
  • 17-4PH forged bar

Forged Stainless Steel Grades & Benefits

Stainless steel has overall benefits of corrosion resistance and machinability, but each grade type of stainless steel comes with its own set of benefits:

Austenitic Stainless Steel

  • Highest impact strength
  • Cryogenic toughness
  • Non-magnetic

Martensitic Stainless Steel

  • High strength
  • Pitting corrosion resistance

Precipitation Hardening (PH) Stainless Steel

  • Extreme strength and fatigue life
  • Moderate toughness

Duplex Stainless Steel

  • Sound combination of strength and corrosion resistance
  • Reliable toughness at room temperature

Quality Assurance

Scot Forge is proud to be ISO 9001:2015 and AS9100D certified, and our team is committed to providing outstanding customer satisfaction. Further pursuance of aerospace products has led to NADCAP accreditation in both Heat Treatment for stainless steel material and Nondestructive Testing.  

Every Scot Forge customer works with a qualified team that will guide each stainless steel forging from the inquiry to order placement, manufacturing then inspection and shipping.
