12Cr1MoVG钢是一种广泛应用于电站,具有较高的热强性能和持久塑性的低合金耐热钢,是用来制造壁温不大于580℃的过热器及再热器管子及壁温不大于540℃的导管、集箱、管道的主要材料。该钢合金总含量小于5%,但其所含Cr、Mo合金元素的固溶强化作用和所含V合金元素与C结合形成VC等碳化物起到的弥散强化作用,使该钢保持较高的组织结构稳定性和持久强度~([1])。
12Cr1MoVG steel is a widely used in power plants, with high thermal strength properties and ductility of low-alloy heat-resistant steel is used to make the wall temperature not exceeding 580 ℃ superheater and reheater tubes and the wall temperature is not greater than 540 ℃ catheter, header, the main pipe material. The total content of the steel alloy is less than 5%, but the solid solution strengthening effect of the Cr and Mo alloy elements contained therein and the dispersion strengthening effect of the carbide containing the V alloy elements and the C alloy formed by the combination of VC and the like make the steel high The structural stability and long-lasting strength ~ ([1]).
