Weathering steel for welding structure is added a small amount of alloy elements to the steel, such as steel, chromium, nickel, molybdenum, niobium, titanium, zirconium and vanadium, to form a protective layer on the surface of the metal substrate. Therefore, this improve the corrosion resistance and has good welding performance. Weathering steel for welding structure is mainly used in bridges, buildings and other structures. Our company can supply weathering steel plate, sheet, strip and sections, A573 Gr 70 carbon steel plate with various shapes.
The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy A573 Gr 70 carbon steel plate products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of A573 Gr 70 carbon steel plate stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.
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 A573 Gr 70 carbon steel plate 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 A573 Gr 70 carbon steel plate 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.
Oxygen (O) is a harmful element in steel such as A573 Gr 70 carbon steel plate. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
