Cobalt Alloy Rod

Cobalt 6b Round bar is a cobalt-based alloy which has great erosion, abrasion and wear resistance. Its wear resistance is due to the chemical composition and is not a product of heat treatment or other hardening mechanisms. Cobalt Alloy Rod is a low coefficient friction which allows it to withdraw galling and seizing. It is useful in areas and applications where lubrication is impractical or difficult. Even under constant erosive environment it provides exceptional cavitation erosion resistance. Due to the elevated temperature exposure its hardness, impact strength, and dimensional stability gets little effected. It maintains high hardness at elevated temperatures and recovers its original hardness upon cooling to room temperature. This unique property, coupled with good corrosion resistance to a multitude of media and superior mechanical properties in relation to its outstanding wear resistant characteristics, makes it versatile and hence it can be used in various applications where wear, corrosion and temperature are concerns.

UNS R30016 Hex Bar is suitable for use in a variety of high wear and erosion applications. Its abrasion resistance allows it to be used as industrial scraper blades and knives in the food processing, textile industries and waste water treatment. It is also used in applications where erosion is an issue such as pumps, nozzles, valves and mixing blades that are moving slurries where cavitation damage is a concern. AMS 5894 Cobalt 6b Flat Bar also has corrosion resistance in a variety of media in addition to being wear resistant. Additional resistance against corrosion can be provided through molybdenum, chromium, nickel and tungsten. It is very resistant to oxidation at ambient temperatures and has good oxidation resistance at elevated temperatures. Cobalt Alloy 6b Square Bar is resistant to different aqueous corrosive media at various temperature combinations and concentration. The carbon content of Stellite 6b Hex Bar makes it more difficult to machine compared to other cobalt based alloys, but tungsten carbide tools can still be used to machine this alloy.

Cobalt Stellite 6b Round Bar can be welded by using a range of methods, including MIG, TIG, shielded metal arc and coated electrode welding. A preheat treatment to 1000°F should be used and maintained to prevent cracking during welding. Ventilation is also needed to minimize exposure to airborne dust, fumes, and particulate matter while grinding, machining or welding. Its standard heat treatment is 2250°F followed by an air cool. Stellite 6b Rod has also found use in industrial sliding wear applications such as in chemical processing for valves and turbine blade components for steam control in the power industry. It can also be found in bearing assemblies in heat treat furnaces.
