Surface treatment method for S690QL bending before cutting

Among stainless steels, austenitic stainless steel has the best process performance. Due to its good plasticity, S690QL bending, austenitic stainless steel can be processed into various plates, tubes and other profiles, suitable for pressure processing. Martensitic stainless steel has poor process performance due to its high hardness. Stainless steel has corrosion resistance, enhanced strength, steel deformation is not easy to crack and environmental protection performance, not easy to rust, and has good ductility and toughness. Stainless steel is suitable for use in harsh environments (indoor and outdoor environments such as humidity, acid and alkali).

Ordinary carbon structural steel S690QL bending has many impurities and low price. The ordinary carbon structural steel is used in places with low performance requirements and low strength, but it has good plasticity, toughness and cold deformation performance. High quality carbon structural steel has less harmful impurities, and its strength, plasticity and toughness are better than those of ordinary carbon structural steel. High quality carbon structural steel is mainly used to manufacture important mechanical parts.

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.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products S690QL bending are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
