Aerospace: Used for manufacturing or repairing aircraft engine blades, turbine components, etc., providing reliable protection under high-temperature and high-pressure environments.
Energy and Chemical Industries: Suitable for surface strengthening of critical components such as valves, pump bodies, and drill bits, significantly improving their lifespan under corrosive and abrasive conditions.
Automotive Manufacturing: Used in hot-end components such as engine exhaust valves and turbochargers, enhancing their high-temperature resistance and wear resistance.
Tooling and Wear-Resistant Components: Used for repairing and strengthening various molds, rolls, screws, etc., effectively resisting abrasive wear and impact.
Q1: What are the main advantages of Stellite 6 powder?
A1: Its core advantages lie in its “three highs”: extremely high wear resistance (especially against abrasive and adhesive wear), excellent corrosion resistance, and outstanding performance in maintaining high hardness at high temperatures (up to 500°C and above).
Q2: Why is powder sphericity important?
A2: High sphericity ensures good powder flowability, which is crucial in 3D printing powder spreading or powder-feed cladding processes, and is the basis for obtaining dense, uniform molded parts or coatings.
Q3: How does it differ from stainless steel or other alloy powders?
A3: Stellite 6 is a cobalt-based hard alloy. Its overall performance in high-temperature wear resistance and corrosion resistance is far superior to ordinary stainless steel, and it also has better impact toughness than tungsten carbide.
Q4: What precautions should be taken before use?
A4: The powder should be stored in a sealed container in a dry environment. For some processes (such as welding), to avoid cracking, appropriate preheating is required depending on the workpiece material, and interpass temperature and cooling rate should be controlled.
