Since it was established in 2000. Based on the domestic rich Q355NH Q415NH Q460NH weather resistant steel product resources and the great steel demand of the international market, our Q355NH Q415NH Q460NH weather resistant steel service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products
Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel Q355NH Q415NH Q460NH weather resistant 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.
After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the Q355NH Q415NH Q460NH weather resistant steel plate should be derusted before cutting.
Corrosion-resistant steel plate significantly improves the corrosion resistance of structural parts and prolongs the service life of structural parts. It can be used to make various structural parts that work in atmospheric environments and corrosive gases and liquids. Plate Q355NH Q415NH Q460NH weather resistant steel delivery status: According to performance and user needs, steel plates can be delivered in hot rolling, controlled rolling, normalizing, annealing, tempering, normalizing + tempering, quenching and tempering.
