EN 10028-5 P355M Introduce
EN 10028-5 P355M is the standard for hot rolled flat products made of steels for pressure purposes. This particular EN norm sets the requirements for flat products of non-alloy steels like P355M, P355ML1, P355ML2 and P420M. It doesn't belong to general standards like EN 10025 or EN 10028-3. EN 10028-5 P355M plates do have various use in the industry in order to meet certain standards of quality and in terms of heat treatment.
Smelting temperature:1352°C - 1835°C
Application:Pressure flat steel products - Part 5: Weldable fine grain steel, thermomechanical rolling
