ams 5894 bar, UNS R30188 Round Bar, Cobalt Alloy 6B Hex/Flat and Square Bars Manufacturers
Stellite 6b round bar, AMS 5894 Haynes 188 Bright Bar, Alloy 6B Cobalt Cold Finished Bars Suppliers in China
Cobalt Alloy 6b Rod is made up of a chromium, nickel, molybdenum, tungsten alloy with carbon, cobalt and iron in the composition. High Temperature Fasteners Inc. is a leading manufacturer and supplier of the different types such as the Ams 5894 Hex Bar and other types. These material rods and bars have high strength values. The minimum yield strength is 90ksi and the minimum tensile strength is 145ksi with 12% elongation and C36 Rockwell hardness.
The UNS R30188 Round Bar is used to make half sleeves and half bushings in screw conveyors, tile making machines, rock crushing rollers, pump lungers, shafting, cement mill equipment and other heavy duty applications. The Cobalt Alloy 6B Flat Bar is very much corrosion resistant and can serve under highly corrosive environments. The specification of these bars is AMS 5894 and they come under different standards according to the DIN, ASTM, ASME and other international standards.
The Stellite 6b Square Bar dimensions vary greatly with the application and there are round, square, hex, rectangular and other custom designs available. The surface could be treated as hot rolled pickled, sand blasting, cold drawn or other polished types. Please feel free to contact us for more information on the different types of the Alloy 6B Cobalt Threaded Bar and others with a full price list.
