carbon structural steel supplier equivalent

Chinese grade of 20# steel plate: No.20American grade: ASTM1020Japanese grade: S20CGerman, British and French grades: C22, C20CMaterial No.: 1.0402, 1.0411Density: 7.85The strength of 20# steel plate is slightly higher than that of 15# steel plate, with little quenching and no tempering brittleness. carbon structural steel supplier, 20# steel plate is generally used for bending and so on processing. The welding performance of arc welding and contact welding is good. When gas welding, the 20# steel plate with thin thickness and strict or complex shape is easy to crack.

High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the carbon structural steel supplier, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.

In order to improve the carbon structural steel supplier corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main carbon structural steel supplier coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking carbon structural steel supplier sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.
