JIS SB 42 JIS G3103 Steel Plate
boiler steel sheet Product Introduction
JIS SB 42 JIS G3103 steel is not as brittle as many other steels due to its higher strength. The strength and hardness of the steel is increased by heat-treating, which makes it more suitable for use in applications with higher temperatures and pressures.
