How to prevent A573 grade 70 carbon steel plate, steel plate cutting cracks? 1. Preheat the steel plate before cutting, and the preheating temperature depends on the quality grade and thickness of the steel plate. However, it needs to be heated evenly. 2. The cutting speed is reduced appropriately, but its reliability is not as good as preheating. It is suggested to preheat the cutting belt with flame gun cavitation several times before cutting, and the preheating temperature should reach about 180℃.
A573 grade 70 carbon steel plate, Q960 steel plate can be used for cold working, bending and cutting. During gas cutting, cracks will not occur even without preheating. When preheating, Q960 quenched and tempered steel should be processed below tempering temperature. Compared with ordinary steel, Q960 quenched and tempered steel has good corrosion resistance, high hardness and good wear resistance.
