Tianjin trimeric Source Trading Co., Ltd. sells Chengde high pressure boiler tubes, Tianyuan, Tianjin Steel 15crmo high pressure boiler tubes, Hengyang Steel, Chenggang p5 and other high-pressure boiler tubes, Beijing 12cr1movG alloy pipe prices, mainly I Tianjin alloy pipe according to prices be entered in May, Tianjin alloy pipe prices steady fall, prices fall over the previous $ 150-300 a month ago. 12cr1movG high alloy pipe for steam pipes, high pressure pipes, 12cr1movG alloy pipe Tianjin trimeric preferred source Trading Company. 12Cr1MoVG high alloy pipe (Alloy pipe) is a kind of seamless steel tubes, and its performance is much higher than the average 12cr2mo high-pressure boiler seamless steel tubes, which contain Cr steel because it is more, its high temperature resistance, low temperature resistance Other seamless steel corrosion resistance is inferior, so the alloy pipe in the petroleum, chemical, electric power, boiler and other industries more extensive use. Tianjin trimeric Source Trading Co., high alloy pipe business. 12Cr1MoVG alloy tube causes and treatment of martensite yellow blocks: at least 900 ℃ heating (ie, above the AC3 point heating), the original organization ferrite, tempered sorbite, bainite for Albright body, cooling fast because only a small amount of ferrite precipitation from austenite, so not all of the austenite transformation into bainite. With the improvement of normalizing temperature carbide dissolution due to a more complete, more uniform austenite content, the continuous cooling curve to the right, in favor of bainite, making carbon-rich, low vanadium austenite, so get bainite more than few amount of martensite. Normalizing the higher the temperature, the austenite grain growth, so organizations get too coarse.
