S420M and S420ML are hot-rolled flat weldable fine-grained structural steel with a thickness less than 120mm. ASTM A514 high strength steel plate, S420 steel is a non-alloy structural steel. The S420ML steel is composed of the following parts: S (structural steel); 420: the yield strength value of structural steel with a thickness less than 16mm: not less than 420; M represents his delivery status, that is, hot mechanical rolling; L: The impact when the temperature is not lower than -50 degrees is marked with a capital letter L.
Pipeline steel is a kind of steel specially used for transporting natural gas and petroleum with special requirements. Why do oil and gas pipelines use pipeline steel as the transportation pipeline? Because pipeline steel has the following characteristics. First, the pipeline steel is strong, and it is not easy to break. If it breaks during transportation, the consequences are unimaginable. Second, the ASTM A514 high strength steel plate, pipeline steel is durable. Pipeline steel is buried deep underground for a long time and has good corrosion resistance. Third, the pipeline steel is resistant to high temperature and will not deform under high temperature.
When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, ASTM A514 high strength steel plate, 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.
