供应2507钢板#耐腐蚀性双相不锈钢板
2507 is a kind of ferrite austenite (two-phase) stainless steel, it has integrated many ferritic steel and austenitic steel is the most beneficial properties, since the 2507 steel chromium and molybdenum content is very high, so has excellent resistance to corrosion, crevice corrosion and uniform corrosion. Two-way microstructure ensures that the steel has the ability of high resistance to stress corrosion cracking, and the mechanical strength is high. The intensity of the 2507 duplex stainless steel and the corrosion resistant ability is stronger, is mainly used in chemical processing, petrochemical and underwater equipment. It has stronger ability to resist chloride corrosion, high thermal conductivity and low thermal expansion coefficient. High chromium, molybdenum and nitrogen content in it has the very high corrosion resistance to pitting corrosion, crevice corrosion and general ability. It also is very high, the impact strength of 2507 alloy is not suitable for use in the above 570 ℃ temperature conditions, has long been under such an environment, its toughness is reduced.
