High strength steel is mainly used in offshore engineering, lifting equipment, construction machinery, container storage tank and other important steel structures with harsh working conditions, hoping to reduce weight. The application of api 5l PSL2 x56 steel pipeline usage, high strength steel can not only reduce material cost, transportation cost and production cost, but also save welding material consumption, welding work hour; reduce post welding stress, preheating temperature and post weld heat treatment requirements.

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. api 5l PSL2 x56 steel pipeline usage, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.

Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing api 5l PSL2 x56 steel pipeline usage steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.

The automobile steel coil and sheets are one of our main steel materials exported to the overseas. For any questions about automobile steel, for example, JIS G3113 SAPH440 api 5l PSL2 x56 steel pipeline usage chemical & mechanical composition, S355MC material specification, S700MC material properties, QSTE 380 TM equivalent, please contact us freely. Our sales person and technician will give you professional answers. And welcome to consult us about automobile steel price.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
