Industry Leaders in Stayblack Plating Finishes
Stayblack is a chemical conversion which modifies the passive oxide layer of the stainless steel leaving the coated steel matt black. The primary applications of this are for turned parts and small pressings. In particular, it is used for fasteners which need to retain a consistent and durable black appearance.
Highly effective and trusted by the military
It is used more specifically in military applications where a black, matt, non-reflective surface is essential for stainless steel. Black steel coatings can be used for clips, aerials, latches and fixings. It can indeed be used for any stainless steel component that needs an alternative to the standard bright, metallic appearance. Stayblack is specified for components in medical, optical and scientific equipment as well as for many varied aerospace applications.
Automotive applications include external and under bonnet fasteners as well as trim accessories.
Withstands Atmospheric Weathering
Stayblack withstands atmospheric weathering, hot water and temperatures up to 500°C without any change in appearance. The coating is less than 1µm thick and will therefore not alter any tolerance fits or change the dimensions of the component to any significant amount. Stayblack does not affect the inherent corrosion resistance of the base stainless steel. It will remain colour consistent longer than an untreated part.
Long-lasting results that stand the test of time
It is a non-electrolytic process and so there is no possibility of hydrogen embrittlement. The surfaces can be deformed after treatment, for example crimped or bent. The coating will not flake, chip or peel. Stayblack can be delivered either dry to touch or with a range of lubricants.
