SPV450 and SPV410 are Japanese Industrial Standard (JIS G3115) steel plates designed for pressure vessels and boilers, suitable for intermediate temperatures, with SPV450 having a higher minimum yield strength (around 450 MPa) than SPV410 (around 410 MPa), both offering good weldability for heavy-duty applications in the oil, gas, and chemical industries, used in reactors, heat exchangers, and storage tanks.
