Grade Overview
Grade 301 stainless steel is typically supplied as strips and wires, achieving tensile strengths up to 1800 MPa across tempers ranging from 1/16 Hard to Full Hard. Its controlled analysis allows sufficient ductility even in ½ hard conditions, making it suitable for aircraft components, rail car parts, and architectural structures. Higher tempers (¾ to full hard) provide excellent wear resistance and spring characteristics for simple form designs.
Grade 301L, the low-carbon variant, offers superior ductility for demanding applications. Grade 301LN contains higher nitrogen content, resulting in an increased work hardening rate compared to standard 301. While only grade 301 is specified in ASTM A666, 301L conforms to JIS G4305 and 301LN to EN10088-2 as grade 1.4318.

Performance Characteristics
Corrosion Resistance
Grade 301 offers corrosion resistance comparable to 304 stainless steel, providing excellent performance in mildly corrosive environments at ambient temperatures.
Heat Resistance
Exhibits good oxidation resistance for intermittent service up to 840°C and continuous service up to 900°C.
Heat Treatment
Subjected to solution treatment annealing at 1010°C to 1120°C followed by rapid cooling. Intermediate annealing uses lower temperature ranges. Thermal hardening is not suitable for this grade.
Cold Working
Grade 301 and its low-carbon variants are primarily used as high-strength stainless steels with exceptionally high work hardening rates (approximately 14MPa increase per 1% reduction in area). Cold rolling and roll forming operations can achieve high strengths while maintaining sufficient residual ductility for severe cold deformation. The alloy is non-magnetic when annealed but becomes strongly magnetic when cold worked.
Welding
Suitable for all standard welding methods using grade 308L as filler metal. Welded 301 components require annealing for maximum corrosion resistance, while 301L and 301LN do not require post-weld annealing. Spot welding effectively assembles cold-rolled 301 components without compromising overall strength.
Industrial Applications
- Rail car structural components
