TUNGSTEN CARBIDE TUBULAR ELECTRODE FOR HIGH PRESSURE ABRASION.
Flux coated tubular electrode containing carbides, which gives low heat input and infinite shelf life. The electrode deposits fine tungsten carbide embedded in a hard and tough martensitic-austenitic matrix. Suitable for extreme abrasion with low to moderate impact. It resists all forms of abrasion and wear.
• Exceptional resistance to severe abrasion and moderate to heavy impact at low to medium temperatures.
• Low spatter level.
• Unmatched deposition rates-high integrity deposits.
• Compared to solid cored electrodes, the current requirement is low so the dilution by parent metal is a minimum.
• Non-hygroscopic coating needs no storage precaution–infinite shelf life.
