SAE AMS2489 2003-JUN-01 Blackenng of Steel Touch Up Method
Purpose:
This specification covers the requirements for an inorganic black coating applied at ambient temperature to steel to touch up black oxide coating in areas where the black oxide has been removed. This coating is intended only to visually change the surface to a black color, not to meet the requirements of any black oxide specification.
Application:
Ambient blackening of steel has been used typically for the touch-up of black oxide surface finish where it has been removed and when complete reprocessing in accordance with a black oxide specification, such as AMS 2485 or MIL-DTL-13924, is not practicable.
Safety - Hazardous Materials:
While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
