BBN supply nm400 weathering steel sheet material

Steel S275J0 is a carbon structural steel grade. Our mill can produce S275J0 carbon steel plates up to 400mm thickness. Generally speaking, as rolled condition for S275J0 carbon steel plate is Ok. Our mill would like to provide customers' normalized delivery condition if they indicate in their purchase order. NM400 weathering steel, Structural steel S275J0 has a specified minimum yield strength at ambient temperature of 275MPa when plates thickness less than 16mm.NM400 weathering steel,The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia,NM400 weathering steel.NM400 weathering steel,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 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 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.When phosphorus, copper, chromium, nickel and other trace elements are added to the 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.NM400 weathering steel,When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
