Product Overview

Stainless steel grade 301 is typically supplied as strips and wires, achieving tensile strengths up to 1800 MPa across tempers ranging from 1/16 Hard to Full Hard. Through controlled analysis, grade 301 maintains sufficient ductility even in ½ hard conditions, making it suitable for aircraft components, rail car parts, and architectural structures. Tempers from 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 applications requiring enhanced formability. Grade 301LN contains higher nitrogen content, resulting in increased work hardening rates compared to standard 301. While 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

Excellent oxidation resistance for intermittent service up to 840°C and continuous service up to 900°C.

Heat Treatment

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 serve as high-strength stainless steels with exceptional 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. The alloy transitions from non-magnetic in annealed condition to strongly magnetic when cold worked.

Welding

Compatible with all standard welding methods using 308L filler metal. Annealing after welding restores maximum corrosion resistance. For 301L and 301LN grades, post-weld annealing is unnecessary. Spot welding effectively assembles cold-rolled 301 components without compromising strength.
