McKay Hardalloy 155 Hard Facing Stick Electrode - 3/16" X 14" - 10 lb Can - S542258-033

Hardalloy 155 deposits on extra high chromium carbide alloy steel intended for overlay on surfaces subjected to extremely severe abrasion. It maintains its hot hardness to 1250°F and has an excellent edgebuilding capability. Hardalloy 155 is designed for overlay on carbon, low alloy, or manganese steel base metals or over a welded build-up base of Hardalloy 32, Hardalloy 118, or Chrome-Mang. Relief check cracking will readily occur with this product. This cracking is not detrimental to the wear properties of the deposit and provides some degree of stress relief for the weld metal.

OPERATIONAL CHARACTERISTICS:

Hardalloy 155 operates with a globular transfer and has minimal slag coverage. It has an excellent edgebuilding capability. A 1/4 inch arc length should be maintained when welding vertical surfaces; the smaller diameters have better operating characteristics. Vertical surfaces may be overlayed by building a series of horizontal beads on a “shelf” using a weave technique.
