Duplex stainless steels have a mixed microstructure of austenite and ferrite, the aim usually being to produce a 50/50 mix, although in commercial alloys the ratio may be 40/60. Duplex stainless steels have roughly twice the strength compared to austenitic stainless steels and also improved resistance to localized corrosion, particularly pitting, crevice corrosion and stress […]

American Boa uses many different materials for expansion Joints one of which is Austenitic stainless steel: Stainless steels may be classified by their crystalline structure into three main types: Austenitic, Ferritic and Martensitic. Austenitic steels have austenite as their primary phase (face centered cubic crystal). These are alloys containing chromium and nickel (sometimes manganese and […]
