15CrMoR(H) hydrogen steel

15CrMoR(H) material is a 15CrMoR steel that has undergone high temperature treatment with hydrogen. The purpose of using hydrogen is to prevent hydrogen corrosion and have the ability to prevent hydrogen embrittlement. Therefore, it is also called hydrogen-resistant steel.

15CrMoR(H) steel PWHT large and small simulation post-weld heat treatment execution process:
Max .PWHT: 620±10°C×(10-12)h
Min .PWHT: 620±10°C×(3-4)h
 
The current application scope of 15CrMoR(H) hydrogen steel:
At present, the heat-strength steel and hydrogen-resistant steel widely used in the world is Cr-Mo steel. Because alloying elements such as Cr and Mo are added to low-carbon steel, the overall performance of the steel is greatly improved. 15CrMoR alloy steel has good high temperature mechanical properties, high temperature oxidation resistance, corrosion resistance, good toughness, process functions and weldability, so it is widely used in the production of petrochemical, coal conversion, nuclear power, steam turbine cylinder blocks, and thermal power, such as large-scale equipment with severe use conditions and complex corrosive media. In the past, most of this type of steel relied on foreign imports.
