Stellite 3 Alloy Is A Cobalt-Based Alloy With Superior Wear, Heat, And Corrosion Resistance.

Stellite 3 Alloy is a cobalt-based alloy known for its outstanding wear resistance, corrosion resistance, and ability to maintain hardness at high temperatures. It is primarily used in environments where extreme conditions such as abrasion, heat, and chemical exposure are prevalent.

Detailed Product Description:

Stellite 3 Alloy has excellent mechanical and thermal properties, making it suitable for various industrial applications. This alloy contains a high proportion of cobalt, chromium, and tungsten, which contribute to its superior performance under harsh conditions.

Chemical Composition:

• Cobalt (Co): 50-60% – Provides high-temperature strength and corrosion resistance.
• Chromium (Cr): 28-32% – Enhances oxidation and corrosion resistance.
• Tungsten (W): 8-10% – Increases hardness and wear resistance.
• Carbon (C): 2.4-3.2% – Improves hardness and strength.
• Nickel (Ni): ≤3% – Further enhances toughness and resistance to corrosion.
• Iron (Fe): ≤3% – Minor presence to control certain properties.

Mechanical Properties:

• Hardness: 53-60 HRC – Offers high wear resistance and surface durability.
• Tensile Strength: Approximately 1,100 MPa – Provides strength to withstand high-stress applications.
• Density: 8.4 g/cm³ – A dense material offering a balance between strength and weight.
• High-Temperature Stability: Maintains hardness and wear resistance up to 500°C.
• Elongation: Low ductility, making it ideal for wear-resistant components but less suitable for deformation or bending.

Corrosion and Wear Resistance:

• Wear Resistance: Stellite 3 Alloy excels in abrasive and sliding wear conditions, making it ideal for cutting, milling, and wear components.
• Corrosion Resistance: Resistant to a wide range of chemicals, including acids, alkalis, and salt solutions, even at elevated temperatures.
• Oxidation Resistance: Maintains its integrity in high-temperature oxidizing environments.

Applications:

• Cutting Tools: Ideal for cutting blades, knives, and wear-resistant components in industrial machinery.
• Valve Seats and Bearings: Used in applications requiring low friction and high wear resistance.
• Aerospace Components: Applied in areas subject to extreme heat and wear, such as turbine blades and engine components.
• Oil and Gas Industry: Suitable for equipment exposed to high-temperature corrosive environments.

Heat Treatment:

Stellite 3 Alloy is typically provided in an as-cast or wrought form, which can be further processed using heat treatments to achieve specific hardness or mechanical properties. The alloy is not designed for large-scale deformation due to its brittleness.

Summary:

Stellite 3 Alloy is a high-performance, cobalt-based alloy that offers outstanding wear resistance, corrosion resistance, and the ability to withstand extreme temperatures. Its robust chemical composition makes it ideal for applications in the aerospace, oil and gas, and industrial machinery sectors, particularly in cutting tools and wear-resistant parts. The alloy’s durability and strength make it a reliable choice for demanding environments.
