Stellite-Type Cobalt Alloy Powder [-270+400]

About Stellite-Type Cobalt Alloy Powder [-270+400]

Stellite-type cobalt-based alloys are known for their exceptional resistance to wear, galling, and corrosion at elevated temperatures. In powder form, these alloys are applied via thermal spray processes to protect critical surfaces in demanding industrial environments. The -270+400 mesh cut (nominally 53 µm to 38 µm) is a common particle size range for high-velocity oxy-fuel (HVOF) and plasma spray systems, where consistent powder flow and controlled melting are essential for coating quality.

This powder is suitable for rebuilding worn shafts, sealing surfaces, valve seats, and other components that require a hard, durable overlay. The cobalt-chromium matrix retains hardness at high temperatures and resists oxidation, making it a practical choice for power generation, oil and gas, and steel mill applications. Because exact chemistry and hardness depend on the specific Stellite grade (e.g., Stellite 6, Stellite 12, Stellite 21), buyers should confirm the alloy composition with their coating specification before ordering.

Thermal Spray Process Compatibility

The -270+400 mesh size is typically optimized for HVOF spraying, where fine particle size and narrow distribution promote dense, low-porosity coatings. It can also be used in plasma spray and, in some cases, flame spray setups. Process fit should always be confirmed on enquiry, as gun type, gas flow, and spray parameters influence deposit efficiency and final coating properties.

Packaging and Handling

Standard pack options include 5 kg tins, 10 kg tins, and 25 kg pails. Packaging is designed to protect powder from moisture and contamination during storage and transit. For bulk requirements or alternative packaging, buyers can specify their needs when requesting a quotation.
