Product Description

D717 Tungsten carbide surfacing electrode
D717Tungsten carbide surfacing electrode with H08A steel rolling, carved into a O shape, the content of cast tungsten carbide cores is above 60% by weight of as cores; coated with basic low hydrogen electrode coating, rely on tungsten carbide transition C and W. arc stability, welding current to DC, and use less.
Applications:
suitable for welding machine parts wear resistant rocks, such as tooth claw back, three roller bit fan blades, strong coal drum, sugar mill, concrete mixer blade.
