15CrMo alloy plate is a heat-resistStructural steel plate (mechanical engineering material): refers to steel that meets a specific level of strength and formability. Formability is expressed in terms of elongation after the tensile test is interrupted. Structural steel is generally used for load bearing and other purposes, in which the strength of steel is a reuse design standard. Structural steel is a kind of special steel.ant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion.
