Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several density of SPA-C weathering bridge steel strip after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.
Advantages of NM360 wear-resistant steel plate: NM360 steel has high strength: generally its yield strength is above 300MPa. 2. High toughness: The elongation is required to be 15% -20%, and the room temperature impact toughness is greater than 600kJ / m ~ 800kJ / m. For large welded components, high fracture toughness is also required. 3. NM360 steel plate has good welding performance and cold forming performance. 4. Low cold and brittle transition temperature.
BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.
According to the different heating and melting methods of wear-resistant steel plate, density of SPA-C weathering bridge steel strip, wear-resistant steel plate also has its own melting welding method. Cast welding is an earlier welding method, which uses the heat released during the oxidation of thermite or magnesium thermite to melt metal: its characteristics are simple equipment and operation, but for wear-resistant steel plate, the welding quality is not high. It is only used to repair the workpiece.
