What is the a516 grade 70 yield heat treatment

Our company was founded in 2000, which initially committed to providing high-quality steel a516 grade 70 yield products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export a516 grade 70 yield steel to the international market, opening up the international steel market.

After adding phosphorus, copper, chromium, nickel and other trace elements to the steel, a dense and highly adherent protective film is formed on the surface of the steel, which hinders the spread and development of rust and protects the substrate under the rust layer to slow down its corrosion rate. The amorphous spinel-type oxide layer with a thickness of about 50μm-100μm formed between the rust layer and the substrate is dense and has good adhesion to the substrate metal.

Different form a516 grade 70 yield, boiler steel plate is one of the most critical materials in boiler manufacturing. Boiler steel plate mainly refers to the hot-rolled special carbon steel and low alloy heat-resistant steel plate used to manufacture important components such as the shell, drum, header end cover, support and hanger in the boiler. Boiler steel plates are often working under medium, high temperature and high pressure. In addition to withstand higher temperatures and pressures, boiler steel plates are also subject to impact, fatigue loads, and water and gas corrosion, resulting in poor working conditions.

a516 grade 70 yield, Stainless steel relies on a very thin, solid, fine and stable chromium rich oxide film (protective film) formed on its surface to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the ability of corrosion resistance. Once the film is damaged for some reason, the oxygen atoms in the air or liquid will continuously penetrate or the iron atoms in the metal will continuously separate, forming loose iron oxide, and the metal surface will be continuously rusted.
