JIS G3454 Carbon Steel Pipe

JIS G3454 Carbon steel pipe specification covers carbon steel pipe for pressure purposes. The mechanical properties of this steel will change greatly after heat treatment. By controlling the cycle of heating and cooling, certain desired properties are obtained by producing predictable changes in the microstructure of the steel.
