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.
Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the 42crmo4 qt equivalent steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its 42crmo4 qt equivalent steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
There are a wide range of steel for nuclear power. Steel grades cover carbon steel, 42crmo4 qt equivalent, alloy steel, stainless steel and nickel based materials, and all have more stringent requirements. Because the steel for nuclear island equipment works in high temperature and high pressure environment for a long time, it is required to have appropriate strength, high toughness and low brittle transition temperature (NDT).
