SB450 Pressure Vessel Steel Plate

 

SB 450 Pressure Vessel Steel Plate, JIS 3103 SB 450 steel plate is a kind of material for boiler and pressure vessel steel. JIS 3103 SB 450 steel plate is characterized by a minimum yield strength of 220 - 295 MPa and by good weldability, so SB 450 steel is mainly used for manufacturing boilers, pressure vessels and pipes transporting hot liquids.
