GB/T 3077 20CrMo steel Alloy structural steel

20CrMo Alloy Structural Steel is a kind of alloy structural steel. Its quench-hardening ability is higher, no temper brittleness. The weldability of 20CRMO steel is quite good. The tendency of cold crack formation is very small, but machinability and cold straining plasticity is good.

Application:
20CrMo Alloy Structural Steel plate/sheet is used make all kinds of fasteners, high pressure pipe and more advanced carburized parts, such as gear, shaft, etc ,which work in the noncorrosive medium and temperature below 250 ℃, working with nitrogen hydrogen mixture in the medium.
