p11 high-pressure boiler tube high-pressure boiler tube _ _ Yibin trimer source Trading

Tianjin trimeric Source Trading Co., Ltd. sells high alloy pipe. 12Cr1MoVG produce yellow block martensitic alloy tube causes and treatment methods: 12Cr1MoVG AC1 phase transition point is about 774 ~ 805 ℃ high-pressure boiler tubes, about AC3 about 882 ~ 923 ℃. Its normalizing temperature theoretically should AC3 + 30 ~ 50 ℃, more that 930 ~ 950 ℃. When performing normalizing heat treatment at 900 ℃ under heating, namely insufficient when normalizing temperature is between AC1 ~ AC3 when p22 high-pressure boiler tubes, the original organization sorbite, bainite austenite The ferrite is not fully dissolved (only at temperatures close to the AC3, a certain amount of ferrite to austenite is dissolved.), due to alloying elements sorbite, bainite area carbon and vanadium in more enriched, and therefore these regions are formed in large austenite stability p5 high pressure boiler tubes, air cooling time and the precipitation in the ferrite, so that more stable austenite transformation failed, it into martensite and bainite easier. Because low heating temperature, austenite grain formation and growth failed to annexation, it transformed martensite and bainite tiny compared. 32-245 produce diameter, wall thickness 6-25; 10-1020 marketable outside diameter, wall thickness of 1-100 and other types of seamless steel tubes. Specializing in the production of heat under pressure, corrosion resistance, wear steel pipe and castings. Main products: heat-resistant steel, heat resistant steel, wear-resistant steel, stainless steel 15crmo high pressure boiler tubes, alloy steel, ultra-low carbon steel, non-magnetic, thick-walled pipe, K alloy castings and other products in the domestic outside the industry are widely used, well received! p11 high-pressure boiler tube high-pressure boiler tube _ _ Yibin trimer source of commerce provided by the Tianjin trimeric source Trading Company.
