Product details

Application of ASTM Tp304L Alloy Steel Pipe a kind of steel widely used in power industry. When used at 500 ℃ - 550 ℃, it has high thermal strength performance. When the service temperature is greater than 550 ℃, its thermal strength performance decreases significantly. Generally speaking, 15CrMo steel is mainly used for high and medium pressure pipes and steam pipes with steam parameter of 510 ℃, heat exchanger pipes with pipe wall temperature of 550 ℃, etc. Similar foreign steels include 15xm in the former Soviet Union, T12 and p12 in the United States, stba22 and stpa22 in Japan and 13CrMo44 in Germany. The microstructure of 15CrMo steel under normal supply is ferrite + pearlite. When 15CrMo steel operates for a long time in the working temperature range of 500 ℃ - 550 ℃, pearlite spheroidization, redistribution of alloy elements between solid solution and carbide and changes of carbide phase structure will occur. With the increase of pearlite spheroidization degree and dilution degree of solid solution alloy elements, the thermal strength and mechanical properties of 15CrMo steel will gradually decrease, and the material will gradually deteriorate or even fail. Therefore, the spheroidization degree of pearlite in the microstructure of 15CrMo steel has been widely used as one of the important indexes to judge the service reliability of the steel for a long time. 15CrMoG alloy steel pipe specification and model: 15CrMoG alloy steel pipe: alloy carbon steel, Steel Group: CrMo serial number: grade 35: 15CrMo sample blank size / mm: 30 heat treatment | quenching | heating temperature | first quenching: 900 heat treatment | quenching | heating temperature | second quenching: - heat treatment | quenching | coolant: air heat treatment | tempering | heating temperature ℃: 650 heat treatment | tempering | cooling agent: Air mechanical properties | tensile strength σ B / MPa, ≥: 440 mechanical properties | yield point σ S / MPa, ≥: 295 mechanical properties | elongation after fracture δ 5 (), ≥: 22 mechanical properties | area reduction ψ (), ≥: 60 mechanical properties | impact absorption energy aku2 / J, ≥: 94 steel annealing or high temperature tempering supply state Brinell hardness hbs100 / 3000, ≤: 179 purpose: for 15CrMoG alloy steel pipe under high temperature environment and certain pressure specification application standard: gb8163-2008
