    Our company can provide various forms of conversion joints. The conversion joint is made of 35CrMo, 42CrMo, and 4137H materials.Quenching and tempering heat treament after rough machining and surface phosphating and nitriding treatment after fine machining of threads, which can effectively eliminate the probability of failure such as thread gluing and breaking,joint expansion and cracking,making it more wear-resistant and easy to disassemble.
     Precision CNC lathes and customized forming cutters are used for thread processing ,which can not only ensure the tight spacing of the conversion joints, but also ensure the precision  and interchangeability of the conversion joints. We can not only produce conversion joints of different materials, lengths,diameters, and wall thickness,also we can customize conversion joints according to the requirements of customers.
