JIS G3454 Grade STPG 370 Specification Covers Carbon Steel Pipes for Pressure Service. Mechanical properties of This steel grades can be varied greatly by heat treating. Through a controlled cycle of heating and cooling, certain desired properties are obtained by producing predictable changes in the microstructure of the steel.
