30CrMo precision tube is a high-precision, high-brightness seamless steel tube produced by cold drawing or cold rolling. Its inner and outer diameters can be accurate to within 0.2mm. While ensuring bending and torsional strength, it is light in weight, so it is widely used in the manufacture of precision mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, shells, bearings, etc. It is also used to manufacture mechanical structures, hydraulic equipment, automotive parts, and steel sleeves.
Features of 30CrMo cold-drawn precision tube:
1. Smaller outer diameter.
2. High precision and good surface quality of cold-drawn finished products.
3. The cross-sectional area of the steel pipe is more complex.
