Quality control.

1. In the smelting process, to ensure high purity and low gas content of raw materials, apart from the required chemical elements, we have strict contolr upon some harmful elements such as P S Pb Sn As Sb and Bi, as well as some gas or nonmetallic debris like H N and O.
2. Strict forging technique is employed both to ensure there are no flows inner the products ,and to keep main shaft’s microstruture consistent with the overall shape of forgings, The comprehensive processing lines commit that the spare parts are of good mechanical properties and long service life.
3. Product will acquire high comprehensive mechanical properties after quenching and high-tempreture tempering treatment . The impact performance is high whether for 42CrMo main shaft of room temperature, or low-temperature 34CrNiMo6 shaft.
4. We employ CNC equipment for finishing to ensure the high processing accuracy of our forgings , The advanced painting and coating technique for corrosion resistance will meet the requirement of long-term filed work.
