S420NL high strength steel plate

S420NL is a fine grain structural steel, European standard high strength steel plate, in accordance with European standard EN 10025. S420NL steel has high comprehensive mechanical properties in the state of normalizing or normalizing plus tempering. S420NL high strength steel plate is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, locomotives and rolling stock, lifting machinery, mining machinery and other large welding structures.

S420NL high strength steel plate delivery status: quenching + tempering. The delivery status can be selected according to the demand, and the flaw detection standard requirements, flaw detection grade requirements, Z-direction performance requirements, special alloy element requirements and classification society certification requirements can also be added. However, it needs to be communicated between the supplier and the demander and indicated in the contract.

S420NL high strength steel plate shall be classified as alloy special steel. S420 grade steel is supplied in the following levels specified in inquiry and order: when the temperature is not lower than - 20℃, the minimum impact energy is specified, expressed in N. When the temperature is not lower than - 50℃, the minimum impact energy is specified, expressed in NL.
