Introduce of 301 Stainless Steel

1/4H hardness of 301 stainless steel is through cold processing (such as cold rolling) to achieve a partially hardened state, with high strength and hardness, while maintaining a certain ductility. This state is suitable for applications requiring moderate strength and good formability.

Main characteristics


Hardness grade:

1/4H: indicates that the material has been hardened by about 25% cold work, between the annealed state (soft state) and the full hard state (H).

Mechanical properties of 1/4H 301 Stainless Steel

  • Tensile strength: about 900-1100 MPa
  • Yield strength: about 700-900 MPa
  • Elongation: about 15-25%
  • Hardness: about 250-350 HV

Corrosion resistance:

  • 301 stainless steel with 1/4H hardness still has good corrosion resistance in medium corrosive environments, but it is slightly lower than the annealed state.

Processing properties:

  • Formability: 1/4H hardness of 301 stainless steel has a certain ductility, suitable for medium complex degree of molding processing.
  • Welding: It can be welded, but after welding, it is necessary to perform solid solution treatment to restore corrosion resistance.

Heat treatment:

  • Solution treatment: heating to 1010-1120 ° C, then rapid cooling to restore corrosion resistance and processing properties.

Application field:

  • Electronic products: mobile phones, computer cases, etc.
  • Automobile manufacturing: body structure parts, springs, etc.
  • Architectural decoration: curtain wall, decorative strip, etc.
  • Aerospace: aircraft structural parts, engine parts, etc.

Sum up
The 1/4H hardness of 301 stainless steel is partially hardened by cold working, has high strength and certain ductility, and is suitable for occasions requiring moderate strength and good formability. Its good corrosion resistance and processing properties make it widely used in electronic products, automobile manufacturing, architectural decoration and other fields. When selecting, its state and heat treatment method should be determined according to specific needs.
