What is DOX-Steel?
DOX-Steel is a nickel-cobalt alloy that is inter-diffused through electro-deposit processes in different steel substrates. DOX-Steel creates a covalent bond with the base metal of only ¾ thousandth of an inch. Interdiffusion is perfectly even in all base metal surfaces.
The result is a coating that has a tremendous capacity to resist highly corrosive environments at extremely high and low temperatures.
DOX-Steel has a very negative hydrogen potential; therefore, it forms a noble galvanic corrosion when in contact with other metals. The resulting alloy is dense, flat, hard, highly reflective, and an excellent heat diffuser. It is also resistant to abrasion, has extraordinary electrical conductive properties, and has a very low friction coefficient.
DOX-Steel compares to and exceeds the corrosion properties of super alloys such as inconel, hastelloy, and other special steel alloys.
DOX-Fasteners are carbon steel fasteners coated with DOX-Steel alloy to protect them from corrosion.
DOX-Fasteners display the following outstanding properties:
- High corrosion resistance
- Lower friction coefficient
- Uniformity of coating
- Any ASTM mechanical properties as substrate
- Excellent heat diffusion
- Excellent electrical conductivity
- Excellent fit & function (no oversize)
- Abrasion resistance
- Outstanding performance in extremely low and high temperatures ( -150° up to 1,000°F)
- Easy installation and removal
- Longer maintenance cycles
- Improves hermeticity in bolted joints
- NO GALLING
- NON-AGGRESIVE (Noble) Galvanic Corrosion
- Can be used in joints with any metal (Carbon, Stainless, Zinc, etc...)
