In today's S420MC automobile structure steel steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of S420MC automobile structure steel market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

There are eight different grades of products under the ASTM A514 TYPE standard: A514GrA, A514GrB, A514GrE, A514GrF, A514GrH, A514GrP, A514GrQ, A514Gr.S. ASTM A514 steel plate has high strength, good cold forming performance and welding performance; high toughness and low brittle transition temperature; it has good corrosion resistance and wear resistance. ASTM A514 steel plate S420MC automobile structure steel as a structural steel plate is widely used in the United States and foreign markets.

Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, S420MC automobile structure steel are strict. In the chemical composition of boiler steel, S420MC automobile structure steel, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.

At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, S420MC automobile structure steel, and there are relatively few cracks and holes. After 25 days, delamination occurs in some parts of carbon steel and weathering steel, and there is no difference in corrosion products, mainly due to the role of alloy elements in the rust layer. The precipitation of Cu and Cr alloy elements in the weathering rust layer can resist the invasion of moisture and harmful ions in the atmosphere, and further corrosion of steel and base metal can be prevented, so as to achieve the effect of atmospheric corrosion resistance.
