Product Process

1.Raw materials entering the factory, 27SiMn, 40CrMo, ST52, 45# steel tubes or bars for choice

2.Do the pre-treatment including pickling, phosphating and saponification, and then cold-draw the seamless steel tubes.

3.Put the steel tubes into the tempering furnace to do the stress relief annealing in convenience of the subsequent the processing.

4.Multi-roll straightening machine, with 10 straightening points, achieves the automatic rolling straighten, improving the efficiency greatly

5.Heat treatment to obtain work pieces with different properties by changing their internal microstructure or surface chemical composition.

6.Cylindrical degree can be controlled within 0.03mm and the surface roughness is up to 0.4 by honing with range: φ40mm-φ450mm and longest length: 12000mm

7.Machining processes to obtain high precision parts with complex shapes strictly according to the detailed drawings.
