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.
Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
We just exported 1500 tons LR grade A hull structure steel plates to Brazil. The customer is introduced by our old customer who used to work for the DETROIT BRASIL LTDA, a famous ship yard in Brazil. They regard us as their Chinese agent, they will inform us no matter when they purchase steel materials from China, if we can not supply the goods, we will inspect the goods for them before the shipment.
