What are the differences between 15CrMoR and 15CrMo steel?

15CrMoR steel is different from 15CrMo steel as we can see from the grades. Below are the comparison of 15CrMoR and 15CrMo steel

Different materials

15CrMoR steel is a boiler steel and pressure vessel plate.

15CrMo material is a type of alloy structural plate.

Implementation standards are different

15CrMoR: GB713-2014, 15CrMoR (H) implementation standard WYJ410-2008

15CrMo: GB/T 3077-2015 steel plate standard

Different applications

15CrMoR: It is used to manufacture large-scale equipment with severe service conditions and complex corrosive media, such as petrochemical industry, coal conversion, nuclear power, steam turbine cylinder, thermal power, etc.

15CrMo steel plates are widely used for petroleum, petrochemical, high-pressure boilers, etc. Special-purpose seamless pipes include boiler seamless pipes, geological seamless steel pipes and petroleum seamless pipes.
