P420M steel plate for pressure vessels

P420M steel plate is a kind of material for boiler and pressure vessel steel. P420M steel plates is characterised by a minimum yield strength of 390-420 MPa and by good weldability,so P420M steel is mainly used to for manufacturing boilers.

P420M steel plate chemical composition:（%）

Grade	P420M max %	element	P420M max %
