Duplex stainless steel<\/b>\u00a0is an alloy with a two-phase metallurgical structure consisting of austenite and ferrite in almost equal parts. The content composition of duplex steel has a higher level of chromium and molybdenum, lower nickel and a percentage of nitrogen between 0.05 to 0.50%.<\/span><\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
