Key features
- Basic coated austenitic manganese steel MMA electrode for wear resisting hard facing deposits and for joining.
- Used for hardfacing or buttering on carbon steels and high Mn steels, the deposit is only machinable by grinding.
- The weld metal will increase in hardness by cold-working, from~ 200-250 HB to ~400-500 HB, therefore it is particularly suitable for components which are subjected mainly to wear, caused by heavy impact and shock.
- When building up several layers, it is recommended that a buffer layer is deposited with 307 type MMA electrode.
- Flat welding position only.
- Shall be used in DC+ current.
