P420ML2 Pressure Vessel Steel
P420NL2 vessel plate is a European standard (EN10028-3) pressure vessel material with a digital code of 1.8913.
P420NL2 boiler plates are usually delivered in standardized condition. In the case of small product thickness and special circumstances, for steel types with yield point ≥ 420 MPa, slow cooling or additional tempering can be performed.
P420NL2 steel physical properties: tensile strength, elastic modulus, plasticity, impact toughness, cold brittleness, hardness, cold bending performance, welding performance, heat treatment performance, cold working performance and aging performance.
