What is Duplex?
Stainless steel duplex is a grade of stainless steel containing 12% chromium and 8% nickel. Stainless steels are a popular choice for manufacturing parts and accessories that are used in harsh environments as they have excellent corrosion resistance. Duplex stainless steel is slightly less resistant to corrosion than Austenitic stainless steel, but it has better mechanical properties. This makes it an excellent choice for uses where strength or formability is important.
