Duplex stainless steel: F51 (2205 S31803 00Cr22Ni5Mo3N..)

2205 penthouse duplex stainless steel alloy is composed of 21% chromium, 2.5% molybdenum and 4.5% nitrogen nickel alloy stainless steel. It has high strength, good toughness and good overall and partial resistance to stress corrosion.
Compared with austenitic stainless steel 316L and 317L, 2205 pitting and crevice corrosion resistance superior, it has high corrosion resistance, compared with austenitic lower its coefficient of thermal expansion, thermal conductivity higher.
Compared with austenitic stainless steel, its compressive strength is twice compared with 316L and 317L, designers can reduce their weight. This alloy is particularly suitable for -50? F / + 600? F within a temperature range, in the case of strictly limited (especially for welded structures), can also be used at lower temperatures.
