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.
MATERIALS
Our Chemi Blacking process will be effective on most low and high
alloy steels with the exception of high chrome austenitic and
martensitic stainless steels.
PROPERTIES
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 increase
resistance to corrosion and increase life of components in service
maintaining a high quality presentable and professional end product.
APPLICATIONS
Suitable for most fasteners including studs, bolts, nuts, washers,
also used on small fabrications, brackets, plates and links.
Sandwell will be pleased to quote for multiple batches or individual components, or send in your components or drawings for evaluation. Restoration and rebuild components also refurbished and re chemi blacked.
Always a quick service, always the highest quality.
