The chemical composition and mechanical properties requirements on sa573 grade 58 structural quality carbon steel plate

Weathering steel plate sa573 grade 58 structural quality carbon steel plate for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate sa573 grade 58 structural quality carbon steel plate has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.

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 sa573 grade 58 structural quality 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 sa573 grade 58 structural quality 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.
