Weldable normalized fine grained pressure vessel steels steel plate

Weldable normalized fine grained pressure vessel steels are characterised 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 pressurised gas (LPG, butane and propane tanks), pressure vessels, steam boiler parts, pressure piping, compressors etc.The following special grades are available for extraordinary applications:
P...NL1 and P...NL2 or P...ML1 and P...ML2 for application temperatures below -20 °C;
P...NH for operating temperatures of up to 400 °C.
The user of these Weldable normalized fine grained pressure vessel steels must make sure that his calculation, design and processing methods are appropriate for the material. The welding technique used must be suitable for the intended application .
The main grade of  Weldable normalized fine grained pressure vessel steels are :
