JIS G3454 STPG370 Carbon steel pipes for high pressure and temperature

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.
