we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.

S315MC high yield strength alloy quality steel, 30CrMnSiA steel has good machinability, small processing deformation and good fatigue resistance. If 30CrMnSiA steel is used to make a tool, it is processed to the tool shape by rough machining. Mill the cutting edge with a cemented carbide milling cutter and polish it with a polishing machine. There should be no problem for the surface roughness reaching 3.2. 30CrMnSiA steel has high strength, sufficient toughness and good hardenability after quenching and tempering. After quenching and tempering, 30CrMnSiA steel can be used for grinding wheel shafts, gears and sprockets.

We have lots of successful cases, for example in July 2015, we exported 5714 tons ASTM A36 mild steel plate to Peru. After receiving the plates and putting then into use, our customer spoke highly of the ASTM A36 mild steel plate quality. In addition, the customer also introduced us an Venezuela customer, who bought 933 tons A36 steel S315MC high yield strength alloy quality steel plate from us. And then in Mar. 2016, due to the first cooperation in July 2015 is very successful. The customer is very satisfied with our product quality and comprehensive service. This time, the customer place an 3989 tons order directly.
