ASTM A666 301 Full Hard Stainless Steel Strip High Strength Cold Rolled Strips for Automotive Parts

Products Specification

SUS301 Full-Hard Stainless Steel Strip

JIS G4313 Standard | Precision Engineered for High-Performance Applications

Product Introduction

SUS301 Full-Hard Stainless Steel Strip is a premium cold-rolled austenitic stainless steel designed for industries demanding exceptional strength, formability, and resistance to corrosion. Conforming to the Japanese Industrial Standard (JIS), this material undergoes rigorous cold-working processes to achieve its full-hard temper, making it a top-tier choice for critical components in high-stress environments.

Core Advantages

• Ultimate Strength: Achieves tensile strength up to 1,700 MPa through advanced cold-rolling, surpassing standard 301 alloys.

• Precision Thickness: Available in ultra-thin gauges from 0.03 mm to 2.0 mm with tolerances as tight as ±0.005 mm.

• Superior Surface Quality: Mirror polish (No.8), hairline (HL), or brushed finishes for aesthetic and functional requirements.

• Fatigue Resistance: Ideal for dynamic applications requiring repeated stress cycles without failure.

• Global Compliance: Meets JIS, ASTM A240, and EU directives (RoHS, REACH).
