Xuper-6804-XHD

Superior Metal-to-Metal Wear Resistance

Xuper 6804 XHD ®

ELECTRODES • Iron based "Super Alloy" • High creep resistance

DESCRIPTION

TYPICAL ANTI-WEAR APPLICATIONS & INDUSTRIES

Xuper 6804 XHD is an iron-based electrode that produces weld deposits that achieve a beneficial hardness value with only a single pass. Deposit properties are optimized to resist high temperature galling and display a high creep resistance and superior metal-to-metal wear resistance at elevated temperatures (1200°F). Xuper 6804 XHD produces deposits that have a reduced cracking sensitivity compared to iron based electrodes of similar deposit hardness.

WELDING PROCEDURE & TECHNIQUE Preparation: Clean weld area of scale and/or oxide. For tool and die preheats refer to the requirements for the specific grade of tool steel. For all other low carbon steels a nominal preheat of 150°F is advised if the part is below 40°F or over 1" thick. For higher carbon steels higher preheats will be needed.

Technique: Maintain a medium-to-short arc and incline the electrode at a 45° angle in the direction of travel.

Excessive weaving (more than 2 times the electrode diameter) is not advised as wide beads can cause excessive base metal overheating and degrade the weld deposit wear properties. The optimum bead width is a stringer bead.

Back whip craters to reduce crater-cracking tendencies.

Post-Welding: Allow parts to slow cool in still air. High carbon steels, air hardenable steels and all tool steels should be covered with a heat-retardant blanket to control the cool-down rate.
