Name Tube-Alloy® 255-O
Brand HOBART®
Category Overlay Flux-Cored Open-Arc Wires
Description Leaves an extra high chromium carbide alloy steel intended for overlay on surfaces subjected to extremely severe abrasion. It maintains its hot hardness to 1250 degrees F.
Applications 3 layers maximum, DCEP
Industries Ammonia Knives, Augers, Bucket Teeth and Lips, Bulldozer Blades, Cement Chutes, Crusher jaws and cones, Crusher Rolls, Cultivator Chisels and Sweeps
AWS No AWS Classification
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. Faster cooling
rates result in a finer, more uniform stress relief cracking pattern.
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.
TYPICAL MECHANICAL PROPERTIES* (As Welded):
Number of As Deposited on
Layers 1020 Steel Mn Steel
Hardness 1 54 Rc 48 Rc
2 56 Rc 50 Rc
3 58 Rc 53 Rc
