Our business scope are ASTM carbon steel, EN carbon steel, Chinese carbon steel materials, JIS carbon steel, ASME carbon steel, DIN carbon steel, etc. The main steel grades are A36, A283C, A572 Gr 50, S235JR, S355JR, SS400, Q235, Q345, S460ML for sale etc. The company has a sound quality assurance system. In order to open up the market and realize mutual benefit, we will serve our customers wholeheartedly with the business philosophy of "price, quality" and "integrity, service"
The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our S460ML for sale steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge S460ML for sale steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.
In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like S460ML for sale, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.
The microstructure of the quenched and tempered alloy steel, S460ML for sale after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.
The company has a professional after-sales service team and good after-sales service reputation, providing full and uninterrupted after-sales service, to ensure timely and rapid solution to customer problems. The company is recognized as a 5-star brand of market quality cost performance and customer satisfaction by Market Research Center, and rated as "AAA credit enterprise of enterprise credit evaluation", and also a leading steel producer and service provider in the world.
