How to avoid the pits on the surface of hardox 400 equivalent

The thickness of our pressure vessel plates, HARDOX 400 equivalent generally ranges 5 to 200mm. According to the working conditions and processing technology of the container, the pressure vessel plate must have good cold bending and welding performance; good plasticity and toughness; high temperature short-term strength or long-term strength performance. In order to make the container can withstand higher pressure and reduce the weight of the structure itself, in addition to high-quality carbon steel, pressure vessel plate is currently made of low-alloy structural steel.

The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.

We have a large number of HARDOX 400 equivalent steel materials in stock, and provide deep processing services such as welding. In addition to simple welding parts, we can also weld H-beam, box column and other profiles. For such welded structure, our advantage is that there are high-quality and low-cost raw material steel plates, which can be cut into the HARDOX 400 equivalent required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, HARDOX 400 equivalent, 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.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
