McKay Tube-Alloy 255-O Hard Facing Self Shielded Tubular Wire - 7/64" Wire - 60 lb Coil - S605539-062

Tube-Alloy 255-O is a self-shielded, flux-cored wire that deposits an extra high chromium carbide alloy steel. It can be used to overlay surfaces subjected to extremely severe abrasion. It can also be used where high temperature (up to 1250°F) wear resistance is required. Tube-Alloy 255-O is designed for overlay on carbon, low alloy, or austenitic manganese base metals or can be used over a weld metal base of Tube-Alloy Build-Up O, 218-O or AP-O.

Stress-relief 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:

Tube-Alloy 255-O has a steady arc with a globular transfer. Spatter and noise levels are minimal. The minimal slag coverage allows it to operate well in automatic applications without slagging between passes.  Out-of-position welding is limited to a horizontal shelf technique. Tube-Alloy 255-O can be run submerged arc by using with a neutral flux.

APPLICATIONS:
Similar to Tube-Alloy 240-O where additional abrasion resistance is required.
