X5CrNi18-12
1.4303Austenitic stainless steel similar to 1.4301 (AISI 304) but with higher nickel content (11-13% vs 8-10.5%) for improved austenite stability and better resistance to stress corrosion cracking. The higher Ni also provides better formability and deeper drawability. C ≤0.06% reduces sensitization risk. Used where enhanced SCC resistance is needed: chemical processing, food industry equipment, pharmaceutical vessels, and heat exchangers in chloride-containing environments.
