What are the precautions for S690QL equivalent din flame cutting

Processing performance of quenched and tempered steel: S690QL equivalent din plate can be used for cold working, bending and cutting. When the gas is cut off, cracks will not occur even without preheating. When preheating processing, quenched and tempered steel needs to be processed below the tempering temperature. Superb wear and corrosion resistance: Because it contains alloy elements such as copper and chromium, it has good corrosion resistance, higher hardness, and good wear resistance compared with ordinary steel.The Performance requirements of low alloy structural steel, S690QL equivalent din:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.If you want to get the ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel price, please do not hesitate to contact us.
