SB450 JIS standard Pressure Vessel Steel Plate

Descriptions:

JIS G3103 specifies the hot rolled steel plates of carbon steel and molybdenum alloy steel to be used for boilers and pressure vessels, excepting those to be used at room and cold temperatures. This standard covers steel SB410, SB450, SB480, SB450M and SB480M.These plates are widely used in the fabrication of boilers and pressure vessels in industries such as petrochemical and manufacturing.
