Postalloy® DuraHard™ 2896-MCG
Postalloy® DuraHard™ 2896-MCG is a non-cracking medium chromium gas-shielded hardfacing overlay designed for applications that require good corrosion, metal-to-metal wear and good abrasion resistance, and a crack-free weld deposit. It can be applied to carbon and alloy steels, and stainless steels. For machine parts and equipment that must be rebuilt back to original dimensions and require a wear resistant overlay in the hardness range of 45 to 50Rc
- Deposits are slag-free
- For machine parts and equipment that must be rebuilt back to original dimensions and require a wear resistant overlay in the hardness range of 45 to 50Rc
Weld Deposit Properties
- Deposits polish in service reducing friction and minimizing wear of the mating surface.
- ood abrasion and wear resistance at elevated temperatures.
- Good corrosion resistance
- Deposit Thickness:
- Deposits thickness unlimited with proper preheat, inter pass, and post-heat
- Heat Resistance:
- Up to 900 °F (482 °C)
- Deposits are machinable with carbide tools and good machining practices.
- 45Rc - 50Rc
