Product Overview
Stellite 12 Alloy is a cobalt-based alloy known for its excellent wear resistance, high hardness, and corrosion resistance, particularly in applications involving high temperatures and abrasive conditions. This alloy combines the beneficial properties of cobalt, chromium, and tungsten to offer outstanding performance in harsh environments.
Chemical Composition
- Cobalt (Co): 50-60% - Base metal, offering high-temperature strength and corrosion resistance.
- Chromium (Cr): 26-32% - Improves oxidation resistance and provides excellent corrosion resistance.
- Tungsten (W): 8-14% - Increases hardness and wear resistance.
- Carbon (C): 1.8-2.4% - Contributes to carbide formation, enhancing hardness.
- Nickel (Ni): ≤3% - Adds to corrosion resistance and toughness.
- Iron (Fe): ≤3% - Minor presence for adjusting mechanical properties.
- Silicon (Si): ≤1% - Aids in deoxidation during production.
- Manganese (Mn): ≤1% - Improves strength and wear properties.
Mechanical Properties
Stellite 12 Alloy offers a balance of hardness and toughness, suitable for challenging environments:
- Hardness: 45-60 HRC - Provides high wear resistance, depending on heat treatment.
- Tensile Strength: Approximately 1,100-1,200 MPa - Ensures strength under mechanical stress.
- Density: 8.5 g/cm³ - Ensures robustness in demanding applications.
- Ductility: Low - Suitable for wear parts with minimal deformation.
- High-Temperature Performance: Retains hardness and wear resistance up to 700°C.
Corrosion and Wear Resistance
Stellite 12 Alloy is highly resistant to various forms of wear and corrosion:
- Wear Resistance: Excellent resistance to both sliding and abrasive wear, especially in metal-to-metal applications.
- Corrosion Resistance: High resistance to corrosion in acidic and alkaline environments, making it suitable for chemical processing.
- Oxidation Resistance: Withstands oxidation at elevated temperatures, maintaining surface integrity in hot, corrosive environments.
Applications
Due to its excellent wear, corrosion resistance, and temperature stability, Stellite 12 Alloy is widely used in:
- Cutting Tools: Ideal for saw blades, knives, and other cutting edges where abrasion resistance is critical.
- Valve Seats and Stems: Used in industrial valves exposed to corrosive or abrasive media.
- Wear Plates and Bearings: Applied in machinery and tools requiring long-lasting wear parts.
- Oil and Gas Industry: Suitable for downhole tools and drilling equipment exposed to harsh conditions.
- Aerospace: Used in components exposed to extreme heat and wear.
Heat Treatment
Stellite 12 Alloy can be heat treated to optimize its hardness and wear resistance:
- Solution Annealing: Reduces internal stresses and enhances corrosion resistance.
- Aging: Increases hardness and wear resistance through controlled carbide precipitation.
- Hardening: Can be further hardened through heat treatments, depending on the application.
Summary
Stellite 12 Alloy is a versatile cobalt-based alloy offering excellent wear and corrosion resistance, particularly in high-temperature, abrasive environments. Its ability to retain hardness and strength at elevated temperatures makes it ideal for industrial, aerospace, and oil and gas applications where extreme conditions are present. The alloy's superior properties ensure durability and reliability in critical wear parts, cutting tools, and valve components.
