• About EN 10207 P265S Boiler Plate Steel
A simple pressure vessel is defined as any welded vessel subject to an internal gauge pressure greater than 0.5 bar which is intended to contain air or nitrogen and which is not intended to be fired.
EN 10207 P265S is steel for pressure purposes (P) with minimum yield strength of 265 MPa (265). It has specified mechanical properties at elevated temperatures. It is delivered in the normalised condition or an equivalent condition obtained by normalised rolling.
