JIS G 3115 SPV 315 steel,JIS G 3115 SPV 315 steel Chemical Composition
JIS G 3115 SPV 315 steel is a kind of material for boiler and pressure vessel steel. JIS G 3115 SPV 315 steel is mainly used to for manufacturing boilers, pressure vessels and pipes transporting hot liquids.
There are five main elements in JIS G 3115 SPV 315 steel, carbon(C), manganese(Mn), phosphorus(P), sulfur(S) and silicon(Si).
JIS G 3115 SPV 315 steel Chemical Composition specific data is as follows:
C % 0.08-0.2
Mn % 0.90-1.50
P % 0.025
S % 0.015
Si % 0.40
In general, phosphorus is harmful element in steel, increases steel cold brittleness, leads welding performance deterioration and cold bending property deterioration, reducing plastic. Therefore usually require steel contains phosphorus less than 0.045%, high quality steel requires less.
Through the above data, JIS G 3115 SPV 315 steel contains 0.025% phosphorus, we can know that JIS G 3115 SPV 315 steel belongs to high quality steel.
