Product Details of Duplex 2205 Stainless Steel Seamless Pipe & Tubes
Overview of Duplex 2205 Stainless Steel
Duplex stainless steel 2205 alloy is a duplex stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance.
Compared with austenitic stainless steel, duplex stainless steel 2205 has twice its compressive strength. Compared with 316L and 317L, the designer can reduce its weight. Alloy 2205 is especially suitable for the temperature range of -50°F/+600°F. Under strict restrictions (especially for welded structures), it can also be used at lower temperatures.
Features of duplex stainless steel 2205
Compared with 316L and 317L austenitic stainless steel, duplex stainless steel 2205 alloy has superior performance in resistance to pitting corrosion and crevice corrosion. It has high corrosion resistance. Compared with austenite, it The coefficient of thermal expansion is lower and the thermal conductivity is higher.
