P355N steel, P355N steel plate
P355N steel grade is one of grade in En10028-3, P355N EN steel is a Weldable normalized fine grained pressure vessel steels,characterized by a minimum yield strength of 275 - 460 MPa, by good weldability and high resistance to brittle cracking. Weldable normalized fine grained pressure vessel steels are used above all for manufacturing vessels for pressure gas(LPG, butane and propane tanks), pressure vessels, steam boiler parts, pressure piping, compressors etc..
P355N steel plate specification:
Thickness: 6mm to 300mm,
Width: 1500mm to 4050mm,
Length: 3000mm to 15000mm
