What is 15GrMoG material?
Thread Content
I have a question regarding the following materials: Are 15GrMoG and 15GrMo the same thing? Are 12Gr1MoVG and 12Gr1MoV the same thing? Are 20 and 20G the same thing? Things like this: some people say that “G” refers to the material used for pipes, others say it refers to high temperatures, and still others say it refers to boilers. Could experts please explain what it actually means? Thank you.
As far as I know, “G” refers to a boiler.
Tubes for boilers. . . Actually, there’s no need to worry about what this means. . . What standard does this pipe you bought meet? Just check that standard. .
Does the G in 15GrMoG refer to the pipe? That means the plate cannot be labeled as 15GrMoG; it can only be labeled as 15GrMo? So what does 15GrMoR mean?
15GrMo is a general alloy structural steel, and G refers to steel used for boilers. .
GUO’s G:P:P:P:P roughly means this
Those with G are boiler tubes, whose standard is generally 5310; those without G are alloy tubes with a standard of 9948. There is a certain difference in their heat resistance, and this has been discussed in detail previously
