Product Description

Product Description

Quenched and tempered alloy structural steel is an alloy structural steel suitable for use after hardening and tempering at high temperatures (500~650 ºC). It is abbreviated as quenched and tempered steel. The quenched and tempered steel is low and medium alloy structural steel, such as 40Cr, 40MnB, 40CrNiMo, 37SiMn2MoV, 18Cr2Ni4w, etc. This type of steel has a good combination of strength, plasticity, and toughness in the quenched and tempered (quenched+high-temperature tempered) state, which means it has good comprehensive mechanical properties. The microstructure in its service state is mostly tempered sorbite composed of a recrystallized fine grained ferrite matrix and dispersed granular carbides distributed within it. It is commonly used to manufacture various important components that require good comprehensive mechanical properties in various mechanical products, such as shaft parts such as machine tool spindles and automotive half shafts, connecting rods, high-strength bolts, and high-strength anchor bolts.
