Stainless Steel Duplex 1.4462 Plates Suppliersin India

Stainless steel duplex 1.4462 sheets, also known as UNS S31803/S32205 or simply duplex stainless steel sheets, are a type of stainless steel alloy that offers a combination of beneficial properties derived from both austenitic and ferritic stainless steels. This particular grade, 1.4462, is characterized by its high chromium (Cr) and molybdenum (Mo) content, which enhances its corrosion resistance and mechanical strength. Here’s a comprehensive overview of these sheets
Composition and Structure Duplex stainless steel 1.4462 typically contains approximately 22% chromium, 5-6% nickel, 3% molybdenum, and 0.15-0.20% nitrogen, along with smaller amounts of other elements such as manganese and nitrogen. This balanced composition results in a two-phase microstructure consisting of roughly equal proportions of austenite and ferrite, hence the term “duplex.” This dual-phase structure contributes to its exceptional combination of mechanical strength and corrosion resistance.
