STL6-332 - Stellite 6 Cobalt Hardfacing TIG Rod 2.5mm (3/32")

Premium Stellite 6 TIG Rods for Industrial Hardfacing

The Stellite #6 TIG Rod (2.5mm) is a premier cobalt-based hardfacing alloy designed for the most demanding industrial environments. Known technically as RCoCr-A under AWS specifications, Stellite 6 is the most widely used cobalt alloy in the world due to its exceptional versatility. It is composed primarily of cobalt, chromium, and tungsten, a formulation that provides outstanding resistance to many forms of mechanical and chemical degradation over a wide temperature range.

This rod is specifically engineered for the Gas Tungsten Arc Welding (GTAW/TIG) process, allowing for precise control over heat input and dilution. The 2.5mm (approximately 3/32 inch) diameter is ideal for fine detail work on smaller components or for building up edges where precision is paramount. Stellite 6 is characterized by its ability to retain hardness at elevated temperatures—a property known as "red hardness"—making it superior to martensitic steels in high-heat applications.

Industrially, this alloy is the go-to solution for protecting parts against cavitation, erosion, galling, and metal-to-metal sliding wear. It is commonly used to overlay carbon steels, stainless steels, and nickel-based alloys. Josef Gas supplies these rods to ensure your maintenance and repair operations have access to high-quality consumables that extend the service life of critical machinery components.

Key Technical Properties

• Wear Resistance: Excellent resistance to low-stress abrasion and adhesive wear.


• Corrosion Resistance: Good resistance to oxidation and corrosion in various chemical media.


• Hardness: Typically achieves 38-45 HRC depending on dilution and cooling rate.


• Machinability: Generally requires grinding for finishing due to its high hardness.
