Can 15CrMoR replace 15CrMoR(H)? What are the differences?

Thread Content

15CrMoR(H) is 15CrMoR that has undergone hydrogen treatment; this treatment further prevents hydrogen corrosion. 15CrMoR belongs to the Container Division of Wugang’s Technology Department, and it is a steel suitable for use in pressure vessels. 15CrMoR (H) is a hydrogen-resistant plate from Wugang, belonging to the Vessel Division of Wugang’s Technology Department. The execution standard for 15CrMoR is GB/T713—2014; the execution standard for Wuyi Iron and Steel’s 15CrMoR (H) grade is WYJ410-2008. It belongs to a type of medium-temperature hydrogen-resistant steel, and it is produced by companies such as Wuyi Iron and Steel, Shougang, Wuhan Iron and Steel, Nanjing Iron and Steel, Xingtan Iron and Steel, Xiangtan Iron and Steel, and Jining Iron and Steel. For immediate delivery or custom rolling, please contact Manager Pang at 136/7495/6041; we can provide information on all original material certificates! Composition details: “15” refers to a carbon content of 0.15%; “Cr” denotes the presence of the chemical element chromium; “Mo” indicates the presence of the chemical element molybdenum; “R” is the first letter of the container plate designation, resulting in 15CrMoR. Heat treatment commonly involves normalizing followed by tempering; at temperatures below 550°C, it provides high durability strength.
