Cobalt Alloy 6B - UNS R30006 Bar

Cobalt Alloy 6B - UNS R30006 Bar is extremely suitable in environments where a high combination of strength, high modulus values and good corrosion resistance are required.

Cobalt Alloy 6B - UNS R30006 Bar is a cobalt-base alloy with excellent corrosion resistance to severe conditions and high temperatures. This nickel cobalt alloy provides outstanding resistance to most types of wear. Stellite 6b® provides inherent wear resistance, it is not the result of heat-treatment, plating, nitriding, or other methods used to produce a superficial hardness on metal parts.

Super alloys have good creep and oxidation resistance, and can function at very high temperatures and severe mechanical stress. Their strength can be increased by solid-solution hardening, precipitation hardening, and work hardening. They are available in different forms, and comprise a wide range of elements in a variety of combinations so as to achieve the desired result. There are three groups of super alloys, namely cobalt-based, nickel-based, and iron-based alloys. All these alloys can function at temperatures above 540°C (1000°F).
