301 Stainless Steel Strip
301 stainless steel strip features high tensile strength, excellent fatigue resistance, and good formability, making it ideal for springs, automotive parts, and structural applications
Product Introduction
301 stainless steel strip is a high-strength, austenitic chromium-nickel stainless steel known for excellent mechanical properties and good corrosion resistance. It is specifically designed for applications requiring high tensile strength and fatigue resistance. Commonly supplied in half hard, quarter hard, and full hard tempers, 301 strip is widely used in springs, fasteners, automotive trim, and structural parts that undergo constant stress or vibration.

Frequently Asked Questions (FAQ)
Q: What is the difference between 301 and 304 stainless steel?
A: 301 has higher tensile strength and work-hardening rate, while 304 has better corrosion resistance.
Q: Do you supply full hard 301 strip?
A: Yes, we offer 1/4, 1/2, full hard and extra full hard options.
Q: Can 301 stainless steel be used for spring making?
A: Absolutely. Its excellent fatigue strength makes it ideal for springs and washers.
Q: Is 301 magnetic?
A: It is non-magnetic when annealed but becomes magnetic after cold working.
