Zinc plated sa573gr.70 carbon steel size

The advantages of sa573gr.70 carbon steel size, hot-rolled clad plates are thin-gauge clad plates of 6, 8, and 10mm thickness. Under hot continuous rolling conditions, it can produce clad steel coils, reduce production costs and meet more user needs. Under the current technical conditions, the hot rolling process cannot directly produce titanium, copper, aluminum and other non-ferrous metal clad plates. In summary, the two very different production processes have their own characteristics, and exist and develop at the same time to meet the vastly different needs of different users.

Hydrogen (H) is the most harmful element in general steel such as sa573gr.70 carbon steel size. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

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.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
