Our 1810mm production line successfully rolled 1.2mm × 1250mm ultra-thin specifications S900MC construction machinery steel high strength automotive steel, and the product quality and performance fully met the standards. In recent years, customers have become increasingly demanding for lightweight vehicles. Our company aims at the market and focuses on the development of thin-gauge high strength automotive S900MC construction machinery steel steel. The research and development personnel adjusted the product composition based on theoretical calculations and drawing on other experiences to meet customers' higher requirements for automotive steel yield strength and tensile strength.

The company adheres to the principle of integrity, standardization and efficiency, wins the market with technology, gains reputation with creative services, and wholeheartedly provides customers with high-quality S900MC construction machinery steel, efficient and fast services. Facing the future, adhere to independent innovation.

The carbon content of S900MC construction machinery steel carbon structural steel is about 0.05% - 0.70%, some of which can be as high as 0.90%. Carbon structural steel can be divided into ordinary carbon structural steel and high-quality carbon structural steel. Carbon structural steel is mainly used in railway, bridge and all kinds of construction projects. Carbon structural steel S900MC construction machinery steel can be used to manufacture all kinds of metal components that bear static load and unimportant mechanical parts and general weldments that do not need heat treatment.

20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, S900MC construction machinery steel. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.

In November of 2015, Thailand one company contacted with us from Internet. They are find the trustable supplier of S355J2H seamless pipe S900MC construction machinery steel for there cable car supporter. Due to the special using of the pipes, they are very careful and servious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and proucts quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1400 tons pipe to us directly.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate S900MC construction machinery steel EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
