Core Technical Specifications & Advantages:
- Superior Wear Resistance: Stellite 6's unique carbide structure provides exceptional resistance to abrasion, galling, and erosion, significantly extending component service life in mining, valve, and pump applications.
- Exceptional Corrosion Resistance: Performs reliably in acidic, alkaline, and saline environments, making it ideal for chemical processing, oil & gas, and marine applications.
- High-Temperature Strength: Maintains structural integrity and hardness at temperatures exceeding 1000°F (538°C), perfect for furnace parts, turbine components, and exhaust systems.
- Impact Resistance: Offers good toughness and resistance to impact even at elevated temperatures, reducing cracking and spalling.
- Low Friction Coefficient: Minimizes wear on mating surfaces, enhancing overall system efficiency.
- Excellent Fabricability: Can be machined, formed, and welded (with specialized techniques) to create complex parts, offering design flexibility.

Frequently Asked Questions (FAQ):
Q1: What distinguishes Stellite 6 from other cobalt alloys like Stellite 1 or Stellite 12?
A1: Stellite 6 offers an excellent balance of wear resistance, corrosion resistance, and high-temperature strength. It has higher chromium and carbon content than Stellite 1 (providing better corrosion/oxid. resist.) and lower tungsten/carbon than Stellite 12 (often making it tougher and more impact-resistant). It's generally considered a versatile, high-performance grade.
Q2: Can ZGTE Stellite 6 plates be machined easily?
A2: Stellite 6 is known for being challenging to machine due to its work-hardening tendency and abrasiveness. Successful machining requires specialized carbide tooling, rigid setups, slower speeds, appropriate feeds, and ample coolant. We often recommend near-net shape casting or specialized grinding/post-processing. Consultation on machining strategies is available.
Q3: What thickness and size ranges are typically available?
A3: We specialize in customization. Typical plate thicknesses range from 5mm (0.2") up to 100mm (4") or more. Widths commonly range from 1000mm (39") to 2000mm (78"), and lengths from 2000mm (78") to 6000mm (236"). Specific dimensions outside these ranges can be discussed based on your requirements and feasibility.
Q4: Is welding Stellite 6 plate possible? What methods are recommended?
A4: Yes, Stellite 6 can be welded, but it requires careful procedures to avoid cracking. Common methods include Gas Tungsten Arc Welding (GTAW/TIG) and Plasma Arc Welding (PAW) using Stellite 6 or similar cobalt-based filler metal. Pre-heating (300-500°C) and controlled post-weld cooling (slow cooling in insulation) are critical. We provide basic welding guidelines; complex welding should be done by qualified personnel.
Q5: What surface finishes are offered?
A5: We supply plates in various conditions depending on application needs: Hot Rolled (HR), Cold Rolled (CR), Annealed, or specific surface finishes (e.g., mill finish, ground) can be arranged. The optimal finish depends on whether the plate is for direct use or further fabrication. Discuss your specific needs with us.
Q6: What is the typical lead time for orders?
A6: Lead time depends on the specific size, quantity, and required processing (e.g., cutting, testing). For standard sizes in stock, shipment can be very prompt. For large custom orders, typical production lead times range from 4-8 weeks. We prioritize providing accurate delivery estimates upon order confirmation.
Q7: Does ZGTE provide material test certificates (MTC)?
A7> Yes, absolutely. As an ISO9001 certified supplier, we provide full Material Test Certificates (MTCs) or Mill Test Reports (MTRs) with each shipment, detailing the chemical composition and mechanical properties (as applicable) of the supplied plates, ensuring traceability and quality compliance.
Q8: What packaging is used for export shipments?
A8: We use robust, export-standard packaging to ensure plates arrive undamaged. This typically involves wooden crates or pallets with protective wrapping (e.g., plastic, waterproof paper) and secure strapping. Specific packaging requirements can be accommodated upon request.
