The blackening of the surface of the G80 marine chain can also be called blue. This is because the chain forms a black oxide film on the surface of the air, chemical solution, appropriate heating temperature or water vapor. Its main component is Fe3O4 . To give everyone a better understanding, let's listen to the detailed introduction of Best Chain.
The blackening of the G80 marine chain is a surface treatment. Unlike heat treatment or quenching, it does not affect the internal structure of the chain, nor does it affect its strength and hardness. Improve the corrosion resistance and aesthetics of the chain.
When the G80 marine chain is blackened, it usually needs to use the blackening pool built by the company, and the processed chain should also be tested by technical personnel, which should mainly test the brightness, blackness and adhesion of the chain. When performing blackening treatment, first put the G80 marine chain into the water containing sodium bicarbonate for cleaning, and then heat-treat in the black pond, take out and remove the debris on the surface of the chain in about half an hour. You can package and leave the factory.
