How to prevent A709 Gr 50 high strength steel, 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℃.
The main difference between A709 Gr 50 high strength steel, 45# steel plate and boiler steel plate is the difference of carbon content and impact toughness. 45# steel is a high-quality carbon structural steel, which is expressed by the number of ten thousand percent of the average carbon content. The 45# steel represents the high-quality carbon structural steel with 0.45 percent carbon content. The high-quality carbon structural steel contains less harmful impurity elements (S, P) and non-metallic inclusions, and has excellent plasticity, toughness and processing technology.
