JIS SB 49 JIS G3103 Steel Plate
boiler steel sheet Product Introduction
JIS SB 49 JIS G3103 is a Japanese industrial standard developed by the Japanese Industrial Standards Committee (JISC). It is a grade of carbon steel used in the manufacture of boilers, pressure vessels, and heat exchangers. The JIS SB 49 JIS G3103 steel is designed for applications with temperatures up to 540 degrees Celsius and pressure up to 100 bar. It can be used to make components for the oil and gas industry, chemical industry, and other industries. It is also widely used in the production of pipes and fittings.
