AISI 301 and Related Stainless Steels 1/2 Hard
VerifiedmetalAISI 301 is an austenitic chromium-nickel stainless steel (17-18% Cr, 6-8% Ni) widely used in aerospace fasteners, springs, and high-strength sheet applications requiring excellent corrosion resistance and work-hardening capability. The 1/2 Hard temper condition provides intermediate strength through controlled cold-working, balancing formability with yield strength (0.2% offset) suitable for applications requiring both processing flexibility and structural performance at cryogenic through moderate elevated temperatures.

Quality & Standards
Industry-Specific
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
