Postalloy® 2894-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, but a crack-free weld deposit. It can be applied to carbon and alloy steels, and stainless steels.
- 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 35Rc.
Weld Deposit Properties
- Good abrasion resistance
- Good corrosion resistance
- Deposit Thickness:
- Deposits thickness unlimited with proper preheat, interpass, and post-heat temperatures.
- Heat Resistance:
- Up to 900°F (482°C)
- Deposits are machinable with carbide tools and good machining practices.
- 28Rc - 36Rc
