Product Description

GB 15CrMo is equivalent to ASME SA387Gr12 , the performance is closer to

SA-387 is a chromium-molybdenum alloy steel plate, which can prevent hydrogen embrittlement, hydrogen corrosion, hydrogen stripping, and sulfide corrosion in a medium temperature (350 ~ 480 ºC) hydrogen environment, and has good low temper brittleness. It is widely used in Manufacture of chemical fertilizers, petrochemicals, and thermal power plant equipment, such as ammonia synthesis reactors, coal gasifiers, shift furnaces, and hydrogenation reactors.

main property

Compared with 12CrMoV steel, this steel has higher oxidation resistance and thermal strength. The creep limit of this steel is very close to the value of enduring strength, and it has high plasticity under the condition of enduring stretching; the manufacturability and weldability of the steel are good, but it needs to be preheated to 300°C before welding, and the stress needs to be relieved after welding deal with.
