Black Oxide for SST

Basics

A thermally produced dark-brown to black oxide conversion coating produced by immersion of a component in alkaline salt solution. The saturation of the colour obtained depends on the nature of the base metal (substrate), the heat treatment, the surface preparation and the composition.
 

Properties

The black oxide products is frequently used to produce a true durable black oxide conversion coating on stainless steel. From the black oxide process, these essentially dimensionless coatings create very decorative, highly durable black finishes that leave an absorbing oxide layer for oils and waxes that will provide for enhanced corrosion protection.

Features and Benefits :

  • No dimensional change
  • Does not affect conductivity
  • Increased corrosion resistance
  • No hydrogen embrittlement
  • Reduced light glare
  • Decorative Finish
  • Provides anti-galling properties
  • Base for organic coatings
 

Materials

A RoHS compliant powdered black oxide product developed to impart a black conversion coating on different types of stainless steel, cast and malleable irons.
Black Oxide for SST
Stainless steel parts treat by black oxide process.

  • Automotive industry
  • Hardware industry
  • Consumer products
  • Medical industry
  • Electronics industry
  • Optics industry
  • Machine tools
