Duplex Stainless Steel

Material characteristics:

Duplex Stainless Steel is a type of steel with the characteristics of corrosion resistance, high strength, easy to process and so on. The physical property of Duplex Steel is between the Austenitic Stainless Steel and Ferritic Stainless Steel; therefore, it combination the excellent toughness and weldability of the former and the higher strength and resistance to chloride stress corrosion of the latter. The ability to resist the Chloride pitting and crevice corrosion is related to the contents of Chromium (Cr), Molybdenum (Mo) and Nitrogen (N) of it. Duplex Stainless Steel performs much better than the ordinary Austenitic Stainless Steel (such as 18-8 304 and 18-12-2 316 ) in resisting pitting, crevice corrosion, stress corrosion and corrosion fatigue especially under the harsh medium environment (such as sea water). The yield strength of Duplex Stainless Steel can reach 400-550MPa which is the double of ordinary stainless steel. Duplex Stainless Steel has good weldability and low hot cracking tendency. Usually, no preheating needed before soldering, and no heat treatment after soldering. It also can be wielded with other kind of stainless steel. Compare to the Austenitic Stainless Steel, Duplex Stainless Steel has large thermal conductivity and small coefficient of linear expansion.
