▎Applications and Features

Weld metal is martensite structure with stable hardness but inferior toughness.
It is difficult to be machined and cut.
It provides excellent arc re-start, slag removal and bead appearance.
It is suitable for severe metal-to-earth wear condition, such as repairing valve brackets, pump linings and blades.

▎Welding Position

▎Welding Instruction

Dry the electrodes at 70-100°C for 30-60 minutes before use.
Preheat temperature should be ≥ 200°C and PWHT should be 600°C.
Use high tensile strength low hydrogen electrode for the buffer layer in multi-layer build-up and base metal with high hardenability.

▎Applications

It is suitable for severe metal-to-earth wear condition, such as repairing valve brackets, pump linings and blades.
