42crmo steel is an ultra-high-strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, good low-temperature impact toughness. 42crmo steel plate is also heat-resistant steel, which has high creep strength and endurance strength at high temperature, and can work for a long time at 500℃.
The advantages of S690QL ASTM equivalent, carbon steel: First of all, the price of carbon steel is low. Compared with stainless steel, galvanized steel, alloy steel, etc., the carbon steel has a great advantage in price. It is a good choice for manufacturers and merchants such as construction sites that use building materials in large quantities. Secondly, the carbon steel is easy to process. In the early days, steelmaking technology was underdeveloped. It was very difficult to manufacture high-precision steel, and carbon steel is widely used.
Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.
