Stainless Steel for Custom Springs & Stampings

AISI 301/ASTM A 666 Stainless Steel

Please note that we do not sell stainless steel or any other materials in raw form. Stainless steel is a material option for custom springs, etc., manufactured by Peninsula Spring.

AISI 301 stainless steel is the most common and affordable type of stainless alloy. It exhibits good corrosion resistance as well as excellent spring properties. AISI 301 stainless steel can be used for high temperatures up to 550°F (288°C).

AISI 301 stainless steel is ideal for custom flat springs and custom sheet metal stampings that require resistance to corrosion and elevated temperatures. To discuss the material requirements of your custom manufacturing project, contact Peninsula Spring today.


Stainless Steel for Custom Springs & Stampings

Nominal Chemical & Physical Properties

  • Cr: 16.0 - 18.0%
  • Ni: 8.0 - 10.0%
  • Minimum tensile strength: psi x 103 240-270
  • Modulus of elasticity: psi x 106 28
  • Maximum operating temperature: 550°F (288°C)
  • Rockwell hardness: C48-52

Heat Treating AISI 301 Stainless Steel

AISI 301 stainless steel is delivered in pre-tempered condition, and, no further hardening can be achieved via heat treating. However, depending on the needs of your application, completed flat springs and sheet metal stampings will undergo a stress-relieving process. 

Manufacturing Springs & Stampings with Stainless Steel

AISI 301 stainless steel is cold drawn to the required temper.

We use stainless steel in a variety of forms, not limited to AISI 301. Our stainless steel options for custom spring and stamping production include:
