SPV355 steel plate is for pressure vessels for intermediate temperature service in JIS G3115-2000 SPV355 Grade has a good weldable and used in high temperature equipment and pressure vessel.JIS G3115 specifies the hot-rolled steel plates with improved weldability to be used for pressure vessels,equipments for high pressure service(excluding those to be used for high temperature and low temperature services). SPV355 steel plates are widely used in the fabrication of boilers and pressure vessels in industries such as petrochemical and manufacturing.
