6mm thick JIS carbon steel SM400C CS plate

SPV490 plate is a Japanese standard steel plate JIS carbon steel SM400C CS plate for pressure vessels, which belongs to low alloy high-strength structural steel. It has high strength, good toughness, low welding crack sensitivity and corrosion resistance. SPV490 steel is mainly used to manufacture petroleum storage tanks. Vertical storage tanks are large containers assembled and welded on site. The welding quality of the welds directly determines the efficiency and life of the storage tank. Currently, high-efficiency automatic welding technology is generally used for welding.

The company specializes in the research and development, production and sales of JIS carbon steel SM400C CS plate seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has JIS carbon steel SM400C CS plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,JIS carbon steel SM400C CS plate rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and JIS carbon steel SM400C CS plate steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and JIS carbon steel SM400C CS plate medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.

After adding trace elements such as phosphorus, copper, chromium, and nickel to Q355NH steel, a dense and highly adherent protective film is formed on the surface of the weathering steel, which prevents rust from spreading and developing, and protects the substrate under the rust layer to slow its corrosion . An amorphous spinel oxide layer of about 50 μm to 100 μm thick formed between the rust layer and the substrate is dense and has good adhesion to the base metal, which greatly improves the atmospheric corrosion resistance of the steel material, JIS carbon steel SM400C CS plate.
