The chemical composition and mechanical properties requirements on density of SMA400AW weather resistant steel

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This density of SMA400AW weather resistant steel rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.

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 density of SMA400AW weather resistant steel, 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.
