Heat-treatment | 1.Nitriding treatment
2.Spray bimetallic coating 3.Electroplating hard chrome |
Quideline of technique
Depth of nitration layer | 0.05~0.08mm |
Hardness of nitration | 900~1000hv |
Fragility of nitration | less than grand one |
Roughness of the surface | Ra0.4 |
Linearity of the screw | 0.015mm/m |
The surface hardness of chrom plating after nitrogention | more than 950hv Chrome-plating layer |
thickness | 0.025~0.085mm |
We perform all process by ourself to have the reliable quanlity. Some of process will be performed for more than three times to have the best quality. That is the reason our screw life time will be doubled or tripled. We also use the best steel from Baosteel, the most experienced and qualified supplier because even 38CrMoAlA has quality of different level.
