About 2205 duplex stainless steel
duplex stainless steel 2205 is composed of 21% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy consisting of duplex stainless steel. It has high strength, good impact toughness and good overall and local resistance to stress corrosion. 2205 stainless steel and 304 316L austenitic stainless steel, mechanical properties, compared to the more dominant advantage, more and more industries have just started to choose 2205 duplex stainless steel as an industrial pipe.
