SPV 24 steel plate, JIS G3115 SPV 24 steel plates is a kind of material for boiler and pressure vessel steel.
JIS G3115 SPV 24 steel plates is characterised by a minimum yield strength of 170-230MPa and by good weldability,
so SPV 24 steel is mainly used to for manufacturing boilers, pressure vessels and pipes transporting hot liquids.
the following are JIS G3115 SPV 24 steel plate's Chemical composition and mechanical properties
