The role of chromium in S355J2WP container steel

The company has formed a production scale of steel plates, steel pipes, steel profiles, and other products, with a planned layout of science, advanced S355J2WP container steel technology and equipment, reasonable resource allocation, environmental protection, energy saving and high efficiency. BBN company has become a large-scale iron and steel enterprise integrating steel S355J2WP container steel production, mineral resource development, steel structure and engineering construction, real estate and modern logistics.

The company is a leading company that sells S355J2WP container steel steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold S355J2WP container steel steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.

Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel S355J2WP container steel. The design of the flame cutting torch provides sufficient oxygen for burning iron oxide to ensure a good cutting effect. The CNC flame cutting machine is a mechanical equipment mainly suitable for the cutting of medium and thick plates. Compared with other similar thermal cutting methods, the CNC flame cutting machine has the characteristics of high cutting quality, good cutting surface perpendicularity, and large cutting thickness.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, S355J2WP container steel, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality S355J2WP container steel products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
