Chemi Blacking

The Chemi Blacking process will be effective on most low and high alloy steels with the exception of high chrome austenitic and martensitic stainless steels. It produces a lustre finish dependent on base material condition which will not significantly affect frictional properties and therefore no adjustment need be made for torque settings on studs, bolts or nuts. Chemi Blacking produces a protective surface that will moderately increase resistance to corrosion and increase life of components in service maintaining a high quality presentable and professional end product.

Chemi Blacking

A cost effective solution, producing a black lustre finish on steel components. This is a cold chemical conversion of the surface resulting in an even black finish.

This is a familiar finish often seen on fasteners both old and new, as well as small machined components. Parts have a protective oil film once blacked to aid corrosion resistance but the coating is not truly weather resistant it is more of a cosmetic finish.
