| Super Hot Hardness and Edge Retention |
| A basic coated hardfacing electrode giving a weld deposit
suitable for rebuilding of hot working tools, forging tools
etc. Intended for hardfacing of hot trimming blades, hot
bar shears etc. Resistance to scaling and tempering is
upto 600°C. |
| |
| The weld-metal gives extremely good spalling
resistance, hot hardness due to grain boundary pinning
by fi ne carbides. |
| |
| ALLOY BASE |
| Fe, Cr, Mn, W, V, Mo, Co |
| |
| SPECIAL FEATURES |
- Weld metal is resistant to scaling upto 600°C
- The weld deposit gives extremely high secondary
hardening
- An excellent edge-retention property for repairing
cutting and shearing tools
|
| APPLICATIONS |
| Highest metal-to-metal wear resistance in upto 500°C
along with good impact resistance. To be used where
cutting, shaving, and piercing proprieties are required to
be maintained. |
| |
| Typical applications are shear blades, roll face repairs,
tools for hot trimming and cold punching, lifting tongs for
billets, high-speed steel dies and tools. |
