AISI 302 — slightly higher carbon variant of 304. Better work-hardening for springs and wire. Standard for stainless springs, wire products and formed stampings.
X5CrNi18-10 (EN 1.4310 / AISI 302) per EN 10088. Higher C than 304 (max 0.12% vs 0.07%) gives better work-hardening for spring applications. Identical corrosion resistance to 304. Standard for stainless spring wire, compression springs, extension springs and formed wire products requiring high spring force.
