Duplex Stainless Steel Pipe SGS Third Party Inspect
Primarily used in chemical plants and piping applications, Duplex Stainless Steel Pipe SGS Third Party Inspect are developing rapidly today and have a microstructure of approximately equal amounts of ferrite and austenite. Duplex stainless steels typically contain approximately 22-25% chromium and 5% nickel with molybdenum and nitrogen. Although duplex and some austenitics do have similar alloying elements, duplexes have higher yield strength and greater stress corrosion cracking resistance to chloride than austenitic stainless steels.
