ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates are structural quality carbon steel plates just as A514 Gr E high strength steel plate. ASTM A573 steel gardes are in three tensile strength ranges intended primarily for structural applications at atmospheric temperatures for which improved toughness is required.
The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural A514 Gr E high strength steel plate steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.
Try to use A514 Gr E high strength steel plate high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the A514 Gr E high strength steel plate temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, A514 Gr E high strength steel plate, 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.
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
