API 5L X70 pipeline steel belongs to ultra-low carbon microalloyed steel. The production of API 5L X70 pipeline steel has almost applied all the new technological achievements in the field of metallurgy for more than 20 years. API 5L X70 pipeline steel is a product with high technology content and high added value. API 5L X70 hot rolled A514 Gr B alloy steel plate high strength pipeline steel is one of the important products in pipeline steel, which requires high precision of hot rolling equipment and difficult process control.
Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from A514 Gr B alloy steel plate. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.
When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, A514 Gr B alloy 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.
