JIS SB46M JIS G3103
Boiler and Pressure Vessel Steel Product Introduction
JIS SB46M 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 steel is composed of iron, carbon, and small amounts of manganese, phosphorus, sulfur, and silicon. JIS SB46M JIS G3103 steel is available in different grades depending on the application. It is commonly used in the production of hot rolled carbon steel plate, pressure vessel plates, and boiler plates. It is heat treated to increase its toughness and strength, and is suitable for high-temperature and pressure applications.
Our company has steel products billets, steel products, hot-rolled sheets, cold-drawn sheets, seamless steel pipes, steel bars and other products. JIS SB46M JIS G3103 has a good reputation in the market, high-quality products, and thoughtful service in the steel industry. JIS SB46M JIS G3103 has complete specifications, and the products are widely used in aerospace, petrochemical, and construction projects, with low requirements for products, easy processing and low dimensional accuracy requirements. And provide cutting, bending, welding, drilling, and other processing services.
Application: Carbon steel and molybdenum alloy steel sheets for boilers and pressure vessels.
Heat treated: 1375°C - 1171°C.
