Stellite 6 Pipe | UNS R30006 Cobalt Alloy Pipe

Description Of Stellite 6 Pipe

Stellite 6 Pipe is a high-performance pipe manufactured from Stellite 6 (UNS R30006), a cobalt-chromium-tungsten alloy known for its exceptional wear resistance, corrosion resistance, and high-temperature strength. Stellite 6 is one of the most widely used cobalt-based alloys, containing approximately 28% chromium, 4.5% tungsten, and 1.2% carbon.

Stellite 6 offers outstanding resistance to abrasion, erosion, and galling, making it ideal for high-wear pipe applications. The alloy maintains its hardness and mechanical properties at elevated temperatures up to 800°C, making it suitable for high-temperature valve and pump components, chemical processing equipment, and high-wear industrial applications.

Stellite 6 pipes are available in custom outer diameters, wall thicknesses, and lengths, with surface finishes including machined, ground, and polished. Typical applications include valve and pump components, chemical processing piping, and high-wear industrial systems.

Features Of Stellite 6 Pipe

• Excellent Wear Resistance: Stellite 6 offers superior resistance to abrasion, erosion, and galling.

• Outstanding Corrosion Resistance: Resists harsh chemicals, acids, and seawater.

• Superior High-Temperature Strength: Maintains hardness and mechanical properties up to 800°C.

• Good Impact Resistance: Cobalt matrix provides toughness to withstand impact loads.

• Non-Sparking: Suitable for use in hazardous environments.

• Customizable Dimensions: Custom outer diameter, wall thickness, and length available.

• Surface Finishes: Machined, ground, polished.

Precautions Of Stellite 6 Pipe

• Health Hazards: Cobalt alloys contain cobalt and chromium, which may cause allergic reactions or respiratory issues. Use in well-ventilated areas. Wear appropriate personal protective equipment (PPE), including gloves and respirators.

• Machining Guidelines: Use sharp carbide tooling, adequate cooling, and appropriate cutting speeds. Avoid generating fine dust. Collect and dispose of machining chips properly.

• Heat Treatment: Follow recommended annealing and aging procedures to achieve optimal properties. Avoid overheating, which can cause grain growth and reduced properties.

• Handling and Storage: Handle with care to avoid surface contamination or mechanical damage. Store in a dry, clean environment.

• Cleaning: Clean with a soft cloth or mild solvent. Avoid abrasive cleaners that could damage the surface.
