Cylinder  Material

Choose the best Material 20 CrMo 40 CrMo 42Crmo, The material of the middle cylinder is made of 20crmo, and is processed by a high-precision CNC center; after the processing is completed, the cylinder undergoes leading heat treatment technology. We have our own heat treatment workshop.; the matching tolerance of the piston and the middle cylinder is within 5-7 wires, and each middle cylinder Both the piston and the piston are cold treated with liquid nitrogen to prevent the cylinder from expanding due to excessive oil temperature and cannot be used normally.
