Main properties of 20CrMn steel plate: high strength and toughness, and good hardenability. The performance obtained after heat treatment is better than 20Cr. The quenching deformation is small, the low temperature toughness is good, and the machinability is good; but the welding performance is low. Generally used after carburizing, quenching or quenching and tempering. 20CrMn steel is used for manufacturing and heavy-duty hardened and tempered parts with large cross section and carburized parts with small cross section.

Composition of low alloy steel plate: Low carbon: due to the high requirements for toughness, weldability and cold formability of low alloy steel plate, the carbon content is not more than 0.20%; manganese is added; the auxiliary elements such as niobium, titanium or vanadium are added; a small amount of niobium, titanium or vanadium forms fine carbide or carbonitride in the steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of low alloy steel plate; in addition, The corrosion resistance of a656 steel properties, low alloy steel plate can be improved by adding a small amount of copper (< 0.4%) and phosphorus (about 0.1%).

The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, a656 steel properties, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.

The results of adopting two-level a656 steel properties service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and a656 steel properties after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.

Analyze the advantages and disadvantages of the products against the competitive a656 steel properties products. Understand the industry situation and future trend. Understand the product brand positioning appeal point, focus on the crowd and development direction. Understand the layout of each market area, and form a big strategic layout view. Understand the basic operation and assessment standards of work responsibilities. Understand the situation of the cooperative customers.
