Prime astm a516 grade 70 round bar corrugated steel roofing sheet

Wear resistant steel plate is a kind of special plate product specially used under the condition of large area wear. At present, the commonly astm a516 grade 70 round bar used wear-resistant steel plate is a plate product made by overlaying a certain thickness of hard and wear-resistant alloy wear-resistant layer on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. The wear-resistant steel plate astm a516 grade 70 round bar consists of two parts: carbon steel plate and alloy wear-resistant layer.

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while astm a516 grade 70 round bar steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of astm a516 grade 70 round bar steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, astm a516 grade 70 round bar, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.
