Stoody Thermaclad 446
Thermaclad 446 is a submerged arc deposit that dilutes carbon from high carbon base metals to avoid retained austenite. It is intended for use as an underlay or butter layer, not as an overlay.
Flux: Stoody R-20
Features
- Abrasion Resistance: Fair
- Impact Resistance: Excellent
- Compressive Strength: High
- Hardness*, HRC: <20
- Surface Cross Checks: No
- Deposit Thickness, in (mm): Up to 3/4 (18)
- Magnetic: Yes
- Machinability: Good with carbide tools
*Hardness will depend on how much carbon is picked up from base metal during welding. 25-30 HRC is typical with 1 layer over 0.80 carbon steel.
