Stoody Build-Up LH
Stoody Build-Up LH deposit is a low alloy steel designed for low severity metal-to-metal wear. The electrode has a special low hydrogen coating which provides a high strength fusion bond on carbon and low alloy steels. As a base alloy for hardsurfacing overlays or for restoring parts to original dimensions, it provides a weld deposit with excellent compressive strength capable of absorbing heavy impact and/or compressive loads.
Features
- It can be applied in multiple layers without cracking, spalling, or mushrooming.
- It is machinable in the as-welded condition with reasonable procedural care and can be forged at red heat.
- It is not recommended for manganese steel or cast iron and does not work harden.
- It should not be used for joining.
