The specification EN 10028:3 covers a range of weldable fine grain steels supplied in the normalised condition and intended for pressure purposes. EN 10028:3 P275NH is steel for pressure purposes (P) with minimum yield strength of 275 MPa (275) which has specified elevated temperature properties (NH).
As well as P275NH we are stockists of other EN 10028:3 plates manufactured and certified to:
EN 10028:3 P355NL1 EN 10028:3 P355NL2 EN 10028:3 P355NH
We also carry stocks of plates certified to EN 10028:2 P265GH
