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

Master Hardfacing with Stellite 6 TIG Rods

When you need to armor-plate a part against extreme wear and heat, Stellite 6 is the rod you reach for. This 2.5mm (3/32") TIG rod is the legendary cobalt-chrome-tungsten alloy that welders trust for critical hardfacing jobs. Whether you are rebuilding a worn valve seat, resurfacing a pump shaft, or protecting a shear blade, Stellite 6 lays down a bead that is tough, smooth, and incredibly durable.

As a welder, you will appreciate the puddle control this rod offers. It flows cleanly under the TIG torch, allowing you to minimize dilution with the base metal—which is crucial for maintaining the alloy's wear-resistant properties. The 2.5mm diameter gives you the versatility to handle both intricate build-ups and general surfacing passes. It bonds well with stainless steel and standard carbon steel, making it a versatile addition to your rod oven or storage tube.

The resulting deposit is resistant to "galling" (where metals stick and tear against each other) and holds its hardness even when the part gets red-hot. This makes it perfect for engine valves, hot shear blades, and chemical handling equipment. Note that because the deposit is hard (around 42 HRC), you won't be filing this down by hand; plan on finishing your work with a grinder or carbide tools. Upgrade your repair capabilities with Stellite 6 and stop replacing parts that you could be fixing.

Application Tips

• Cleanliness: Ensure the base metal is completely free of oil, grease, and oxides before welding.
• Preheat: Preheating the workpiece (typically 200°C - 400°C) is often recommended to prevent cracking, especially on heavier sections.
• Cooling: Slow cooling is essential to avoid stress cracks in the hardfacing layer.
• Gas: Use 100% Argon for the best arc stability and puddle protection.
