Properties of S420NL structural steel hot rolled

Hot rolled S420NL structural steel is treated with a combination of niobium, vanadium and titanium. After normalizing, the yield strength of the trial steel plate is higher than 410MPa and the tensile strength is higher than 550MPa. The transverse and longitudinal impact energy at -50℃ is greater than 140J. The composition and content of the trial S420NL steel plate and The process design is reasonable and the performance is excellent.

Normalizing weldable fine-grained S420NL structural steel (referred to as S420NL) is specially used to produce heavy-duty parts of welded structural parts under low temperature working conditions, such as bridges, flood gates, storage tanks and water supply tanks. Delivery after fire treatment. The European standard EN10025-3 has high requirements for the strength and welding performance of this grade of steel. The steel plate with a thickness of 63mm or less is required to have a yield strength greater than 390MPa and a tensile strength greater than 520MPa after normalizing. At the same time, in order to ensure good welding performance of S420NL steel plate, the carbon equivalent is required to be less than 0.48%.
