What is 1cr0.5mo (H) material? 1cr0.5mo (H) tensile yield strength

1Cr0.5Mo(H) What material is it ,1Cr0.5Mo(H) Tensile yield strength

 

15CrMoR And 1Cr-0.5Mo Can it be equivalent ？

Not a standard material , It can be said that they are similar , It can't be said to be the same . Not a standard material will make a difference , It's like SA516Gr70 The materials can be considered to be consistent with the national standard Q345R Close , But we can't say the same , There is a difference , Pay attention to the distinction , Even if the cost and performance are similar , Also pay attention to , It cannot be completely substituted . Unless there is a standard that says the two materials can be used equally , There is an authoritative comparison table or written approval of the design . Wuyang Iron and steel sun fan
