FAQs

What is a duplex stainless steel flange?

Duplex Stainless Steel Flange: An austenitic-ferritic stainless variant with higher stress corrosion cracking resistance compared to austenitic 304 and 316 stainless, but with lower toughness and impact strength. This category includes grades 2205, F51, F53, and F60.

What is duplex S31803?

UNS S31803/2205: A duplex stainless steel grade with a ferritic-austenitic microstructure, containing around 40-50% ferrite in the annealed condition. This structure provides the high strength of ferritic grades while retaining the corrosion resistance of austenitic grades.

What is uns S31803 material?

UNS S31803 material is a duplex stainless steel with a microstructure consisting of approximately 50% austenite and 50% ferrite.
