McKay Tube-Alloy 258-O Hard Facing Self Shielded Tubular Wire - 1/16" Wire - 25 lb Spool - S605819-029

Tube-Alloy 258-O is a self-shielded, flux-cored wire that deposits a premium martensitic alloy steel of the H-12 tool steel composition. It has excellent resistance to adhesive (metal-to-metal) wear. It also has good resistance to abrasion and impact, and maintains its hardness up to 1000°F. It is designed for use as an overlay on carbon and low alloy steels, or can be used over a base of Tube-Alloy Build Up-O. Because of its high hardenability, proper preheat may be required for crack-free deposits. Tube-Alloy 258-O should never be used for joining.

OPERATIONAL CHARACTERISTICS:

Tube-Alloy 258-O has a steady arc with a globular transfer. Spatter and noise levels are minimal, with a complete, easily removed slag cover. Out-of-position welding is limited to a horizontal shelf technique.

APPLICATIONS:
• Coupling Boxes
• Dragline Chains
• Kiln Trunnions
