• Phosphorus (P) : ≤0.045%
• Sulfur (S) : ≤0.030%
• Chromium (Cr) : 16.00-18.00%
• Nickel (Ni) : 6.00-8.00%

Mechanical properties of 301 Stainless Steel

• Tensile strength: ≥515 MPa (annealed)
• Yield strength: ≥205 MPa (annealed)
• Elongation: ≥40% (annealed)
• Hardness: ≤ 201HB (annealed)

Corrosion resistance:

• 301 stainless steel has good corrosion resistance in the annealed state, but the corrosion resistance will decrease after cold working. Suitable for general atmospheric environment and weak corrosive media.

Processing properties:

• Cold processing: 301 stainless steel through cold processing can significantly improve the strength and hardness, suitable for high strength requirements of the occasion.
• Welding: Conventional methods can be used for welding, but after welding, solid solution treatment is required 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:

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

Sum up
301 stainless steel through cold processing can significantly improve the strength and hardness, suitable for high strength requirements of the occasion. Its good corrosion resistance and processing properties make it widely used in aerospace, automobile manufacturing, electronic products and other fields. When selecting, it is necessary to determine its state (annealing or cold working) and heat treatment method according to specific needs.
