JIS G 3103 SB 450 steel, JIS G 3103 SB 450 steel equivalent grade
JIS G 3103 SB 450 steel is a kind of material for boiler and pressure vessel steel. JIS G 3103 SB 450 steel is characterized by a minimum yield strength of 220 - 295 MPa and by good weldability. So JIS G 3103 SB 450 steel is mainly used to for manufacturing boilers, pressure vessels and pipes transporting hot liquids.
Boiler and pressure vessel steel has many advantages, such as, good strength, good toughness and low effectiveness of the tendency, good weldability and resistance to intergranular corrosion and so on. So, Boiler and pressure vessel steel has many applications.Boiler and pressure vessel steel is commonly used throughout the oil industry (including inshore and offshore), the petrochemical industry and the gas production industry.
