The processing of nitriding screw is a plastic mechanical screw made by a lathe, which is put into a nitriding furnace and filled with nitrogen under a certain temperature and humidity environment. After a certain nitriding cycle, a nitride layer with relatively high hardness is formed on the surface of the screw. This improves the abrasion resistance and durability of the screw.
