sc6b125t - Stellite 6 Cobalt Hardfacing TIG Rod 1/8" (3.2mm)

Premium Stellite 6 TIG Rod for Hardfacing Applications

The Stellite #6 TIG Rod (3.2mm / 1/8") is the industry standard for cobalt-based hardfacing alloys, designed to provide exceptional resistance to wear, galling, and corrosion. Widely recognized as the most versatile Stellite alloy, Grade 6 (AWS RCoCr-A) combines excellent mechanical properties with superior chemical stability over a wide temperature range. This rod is specifically engineered for the Gas Tungsten Arc Welding (GTAW) process, ensuring clean, high-quality deposits on critical components.

Stellite 6 retains its hardness at elevated temperatures ("red hardness"), making it the ideal choice for applications involving thermal shock and high-heat abrasion. Its low coefficient of friction allows for effective metal-to-metal sliding wear resistance, preventing seizing and galling in moving parts. Common industrial applications include the surfacing of valve seats, pump shafts, bearings, shear blades, and extrusion screws where durability is paramount.

Key Performance Characteristics:

• Wear Resistance: Outstanding protection against cavitation, erosion, and adhesive wear.


• Corrosion Resistance: Resists oxidation and chemical attack in harsh environments.


• Machinability: Deposits are generally machinable with carbide tools, though grinding is recommended for precision finishes.


• Versatility: Suitable for joining and overlaying on stainless steels, carbon steels, and nickel-based alloys.

By choosing Stellite 6, industries can significantly extend the service life of machinery parts exposed to severe operating conditions, reducing downtime and maintenance costs.
