McKay Hardalloy 32 Hard Facing Stick Electrode - 1/4" X 14" - 50 lb Can - S540181-035

Hardalloy 32 deposits a heat-treatable steel alloy designed for build-up of carbon and low alloy steels.  High compressive strength makes it an excellent base for harder or more abrasion-resistant overlay alloys.  It has good resistance to cracking, even in multiple-pass deposits. Hardalloy 32 is not limited to a maximum number of layers of build-up. The deposit hardness is well within the machinable range, making it well-suitable for overlay of shafts, gears, and other components which require machining. Hardalloy 32 should never be used for joining.

OPERATIONAL CHARACTERISTICS:

Hardalloy 32 operates well at the high end of its amperage range. The coating provides a smooth, stable arc with low spatter loss. Weaving up to four times the electrode diameter is satisfactory.  Diameters 1/8” and 5/32” can be used out-of-position using reduced amperage, building a series of horizontal beads on a “shelf”, and by using a weave technique.
