301 Stainless Steel Plate
The 301 stainless steel plate is a versatile and high-strength material that falls under the austenitic stainless steel category. Known for its excellent formability and corrosion resistance, 301 stainless steel is an ideal choice for a variety of applications across numerous industries.
- Product Introduction
301 Stainless Steel Plate redefines the balance between strength and flexibility. With a unique composition (17% chromium, 7% nickel, 1% manganese), it achieves 1.200 MPa tensile strength after cold working-ideal for applications requiring spring-like elasticity or structural rigidity. From retractable smartphone components to earthquake-resistant building brackets, 301 adapts to high-stress environments where 304 or 201 grades fall short.
3 Innovations That Elevate Performance
Work Hardening Mastery
Gains 40% strength post-rolling (vs. 304's 15%), perfect for stamped hinges and conveyor belts.
Fatigue Resistance
Withstands 10⁷ cycles at 500 MPa stress (ASTM E466), critical for robotics and medical actuators.
Slim Yet Sturdy
Maintains ductility even at 0.5mm thickness (25% thinner than 304 equivalents).
Technical Edge: Designed for Precision Fabricators

Expert Guidance
Q: How to optimize cold-rolling for spring applications?
A: Target 1/4 to 1/2 hard temper (HRB 85–95) for optimal elasticity-to-strength ratio.
Q: Can 301 replace aluminum in lightweight designs?
A: Yes-301 at 0.8mm matches 1.2mm aluminum's strength with better corrosion resistance.
Q: Welding precautions?
A: Use ER308L filler rod and limit interpass temperature to 150°C to prevent cracking.
Q: Minimum order for custom annealing?
A: 500kg for stress-relieved or bright annealed plates.
