    APPLICATIONS:

    It is used for cladding shafts and valves of carbon steel or alloy steel whose surfacing temperature is below 450  °C.

    CHARACTERISTICS:

    D507 is a surfacing electrode with low hydrogen sodium coating.

    The surfacing metal is 1Cr13 semi ferrite high chromium steel.

    The hardfacing layer has the characteristics of air quenching, generally does not need heat treatment,

    and its hardness is uniform, and it can also be annealing-softing in the range of 750°C -800°C .

    Dual purpose, good welding process. Heated to 900-1000°C, it can be re hardened after air cooling or oil quenching.  

    DC reverse connection is available.
