mti.memberclicks.netthe 300 series stainless steels is classically transgranular. Duplex Stainless Steels. The duplex stainless steels were developed to exhibit comparable general corrosion resistance as 316SS, but with reduced susceptibility to chloride stress corrosion cracking. The higher alloyed duplex stainless steel alloys, ones with significant molybdenum and
