The difference between S31803 and S32205

Duplex stainless steels account for >80% of the consumption of duplex, super duplex and hyper duplex grades. Developed in the 1930’s for application in paper and pulp manufacture, duplex alloys are based around a 22% Cr composition and the mixed austenitic:ferritic microstructure that delivers desirable mechanical properties. Compared with the generic 304/316 austenitic stainless steels, […]
