FAQ

Q: How do you ensure material traceability?

Q: What packaging methods do you use for international shipments?

A: We use packaging solutions based on product type, dimensions, and shipping method:
• Anti-rust wrapping or VCI paper to prevent corrosion during sea freight.
• Wooden cases or steel frames for heavy or large-dimension items such as bars and plates.
• Reinforced packaging with cushioning materials for machined components.
• Shrink wrap and protective film for strip and coil products.
• Moisture barrier bags and desiccant for products requiring extra protection.
• All wooden packaging complies with ISPM 15 standards for international shipping.

Q: What is the difference between Stellite 1 and Stellite 6? When should I use each?

A: Stellite 1 has higher carbon content (2.0-2.5%) and tungsten (12-14%) than Stellite 6, making it significantly harder (HRC 50-56 vs. HRC 38-44) but more brittle. Use Stellite 1 for extreme wear applications with minimal impact, such as valve trim, pump impellers, and cutting tools. Use Stellite 6 for applications requiring a balance of wear resistance and impact toughness, such as valve seats, pump sleeves, and general hardfacing.

Q: What is the maximum operating temperature for Stellite alloys?

A: Stellite alloys maintain their hardness and wear resistance at elevated temperatures. Most cobalt-based alloys can operate continuously up to 750-800°C, with short-term exposure up to 850-870°C. At 760°C, Stellite 6 maintains approximately 30 HRC, while Stellite 21 maintains approximately 18 HRC. For applications above 800°C, we recommend consulting our technical team for specific grade selection.

Q: What is the difference between Stellite 6 and Stellite 21? When should I use each?

A: Stellite 6 and Stellite 21 serve different application needs:
Stellite 6:
• Nominal composition: 28-32% Cr, 4-6% W, 1.0-1.4% C, Co balance.
• Hardness: HRC 38-44.
• Offers the best balance of wear resistance, corrosion resistance, and toughness.
• Provides good resistance to galling and seizing.
• Widely used for valve seats, pump sleeves, bearing surfaces, and general hardfacing.
• Good weldability and machinability among cobalt alloys.
• Preferred choice for applications requiring a combination of wear resistance and impact resistance.
Stellite 21:
• Nominal composition: 26-30% Cr, 5-6% W, 0.2-0.3% C, Co balance.
• Hardness: HRC 28-38.
• Lower carbon content provides better toughness and thermal shock resistance.
• Superior resistance to thermal fatigue and thermal cycling.
• Excellent welding performance with low preheat requirements.
• Used for applications involving rapid temperature changes, such as nuclear valve sealing surfaces, gas turbine components, and thermal shock environments.
• Better machinability compared to high-carbon Stellite grades.
Selection guidance: Choose Stellite 6 for general wear applications requiring good wear resistance and toughness. Choose Stellite 21 for applications with severe thermal cycling where thermal shock resistance is more critical than maximum hardness.
