Steel grade and pipe grade
Thread Content
May I ask: Is the steel grade applicable only to the steel itself, and has nothing to do with its subsequent condition? For example: Steel grade 20 can be processed into 20-grade steel pipes, which are used for transporting ordinary media ； It can also be processed into 20G steel pipes for use in the steam pipelines of high-pressure boilers. The steel used for both types of pipes is grade 20 steel, with the same grade. So, does the pipe still have a grade? Is 20G a grade for pipes? Please ask an expert to let me know.
20# and 20G are two different grades of steel
