SPV315 and SPV490 are Japanese standard (JIS G3115) pressure vessel steel plates, with 'SPV' indicating they're for boilers/pressure vessels and the number representing minimum yield strength (315 MPa for SPV315, 490 MPa for SPV490); they offer good weldability, specified tensile strength ranges, and are used in applications like reactors, heat exchangers, and storage tanks, with SPV490 being the higher strength grade.
