EN P 420 ML 2 EN 10028-5
Boiler and Pressure Vessel Steel Product Introduction
EN P 420 ML 2 EN 10028-5 steel is a stainless steel designed to meet the needs of the European Union's Pressure Equipment Directive (PED) for high temperature applications. The steel is primarily used in the construction of components for pressure vessels, boilers, and other equipment that require a steel that can withstand the extreme temperatures and loads generated in these environments. The steel has good weldability, excellent corrosion resistance, good formability, and exceptional mechanical properties. It is one of the few steels that meets the PED requirements with relatively low cost.
