The bridge steel plate produced by BBN company has pure steel, flat and smooth plate surface, small difference between plates, -40 ℃ impact value and aging impact value are stable, and the margin is large. Bridge steel plates can be controlled by rolling, cooling, normalizing, and tempering organize production with different production processes. This bridge steel A573 grade 70 carbon steel is widely used in the manufacture of large railway bridges and highway bridges.
Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, A573 grade 70 carbon steel weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent,A573 grade 70 carbon steel.
As the thickness and hardness of A573 grade 70 carbon steel increase, the tendency to crack at the cutting edge increases. In order to prevent the from cutting cracks, preheating should be carried out before cutting. Special attention should be paid to preheating to make the entire interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole cannot be preheated, the partial preheating method can be used instead.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
A573 grade 70 carbon steel,After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
