Duplex stainless steel 2205

Standard No.: ASTM A240/A240M--01 2205 duplex stainless steel alloy is 21% chromium, 2.5% and 4.5% nickel-molybdenum alloy composition of nitrogen duplex stainless steel. It has high strength, good toughness and good overall and partial resistance to stress corrosion. 2205 duplex stainless steel is austenitic stainless steel yield strength twice, this feature allows designers to reduce weight in the design of products, so this alloy is more than 316,317 L has a price advantage. This alloy is particularly suitable for -50 ° F / +600 ° F temperature range. Beyond this temperature range applications, this alloy can also be considered, but there are some limitations, especially when applied to welded structures.

Features:
1 2205 duplex stainless steel alloy 316L and 317L austenitic stainless steels, 2205 is in the anti-pitting and crevice corrosion resistance superior to, it has high corrosion resistance, compared with the austenite, which lower coefficient of thermal expansion, thermal conductivity higher.
2 2205 duplex stainless steel alloy and austenitic stainless steels, it is twice the compressive strength, compared with 316L and 317L, designers can reduce their weight. 2205 is especially suitable for -50 ° F / +600 ° F temperature range, in strictly limited circumstances (particularly for welded structures) can also be used to lower the temperature.

General properties
Xinhui Steel Union of 2205 duplex stainless steel production by 22% chromium, 3% molybdenum and 5-6% nickel, nitrogen composition of duplex stainless steel. It has high strength, good toughness and good overall and partial resistance to stress corrosion. With 316L and 317L austenitic stainless steels, alloy 2205 pitting and crevice corrosion resistance superior performance aspects, it has high corrosion resistance, compared with the austenite, its lower coefficient of thermal expansion, thermal conductivity is higher.
