Duplex stainless steels are virtually immune to stress corrosion cracking (the Achilles heel of common austenitic stainless steels) and are highly resistant to pitting and crevice corrosion. Possessing these characteristics, it is not surprising to find the majority, but by no results for this questionHow do duplex stainless steels get their name?How do duplex stainless steels get their name?Duplex stainless steels get their name from their two-phase microstructure. While exact ratios vary by grade, most duplex steels have a structure that is roughly 50-percent austenite and 50-percent ferrite. This gives duplex stainless many of the perks of austenitic and ferritic families of steel while also minimizing the weaknesses.A Guide to Duplex Stainless Steel What is It? - Unified Duplex stainless steels Complete Guide results for this questionWhat is 2205 duplex stainless steel?What is 2205 duplex stainless steel?Nitrogen is added to the second generation duplex alloys and provides strength and improved weldability.
