What is the application of A572 grade 42 carbon steel plate sheet

The alloy wear-resistant layer of the wear-resistant steel plate is mainly made of chromium alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are also added. The carbide in the metallographic structure is fibrous, and the fiber direction is perpendicular to the surface; alloy carbide It has strong stability at high temperature, maintains high hardness, and also has very good anti-oxidation performance. A572 grade 42 carbon steel plate sheet, wear-resistant steel plate can be used normally within 500 ℃.

Weathering steel plate refers to the low alloy structural steel with protective rust layer and atmospheric corrosion resistance, which can be used to manufacture steel structures such as vehicles, bridges, towers, containers, etc. Compared with A572 grade 42 carbon steel plate sheet, ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only a small amount of alloy elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium and so on. The total amount of alloy elements only accounts for a few percent, instead of more than 10 percent as stainless steel, so the weathering steel price is relatively low.

In order to improve the A572 grade 42 carbon steel plate sheet 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 A572 grade 42 carbon steel plate sheet coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking A572 grade 42 carbon steel plate sheet 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.
