ASTM A 53 A514 Gr M alloy steel plate covers seamless and welded steel pipe with nominal wall thickness. The surface condition is usually black and hot-dipped galvanized. ASTM A 53 A514 Gr M alloy steel plate is produced mainly for pressure and mechanical applications, and is also used for transport of steam, water, gas line pipes.
In production and operation, the company always attaches great importance to product A514 Gr M alloy steel plate quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market A514 Gr M alloy steel plate. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.
The cold bending method is mainly used to produce cold-formed section steel and welded pipe. The cold bending method is to bend the steel strip or steel plate into various cross-section shapes by the cold bending machine in the cold state. If the A514 Gr M alloy steel plate steel pipe is bent into a circular, square or other hollow shape and welded by a proper welding method, it is a welded pipe. The advantages of cold bending: first, the cold-formed section steel is light in weight and large in bearing capacity, and it can save metal by replacing the hot-rolled section steel; second, it can produce all kinds of A514 Gr M alloy steel plate extremely thin, extremely wide and complex section steel which can not be produced by hot rolling.
The chromium plays an important role in A514 Gr M alloy steel plate, Chromium Molybdenum steel. The chromium can form a dense oxide film with strong adhesion on the surface of the steel plate, so as to prevent the internal metal from further oxidation or corrosion. The higher the chromium content in the steel plate, the denser the oxide film, and the better the oxidation resistance and corrosion resistance of the steel plate.
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
