Stellite

Stellite is a high temperature alloy, mainly composed of cobalt (Co) base, with excellent wear resistance, corrosion resistance and high temperature resistance. Stellite alloy is widely used in various industrial fields, especially those that need to work in harsh environments, such as aerospace, petrochemical, power generation and nuclear industries.

Main components:

Cobalt (Co)

The main matrix element of Stellite, providing high temperature strength and oxidation resistance.

Chromium (Cr)

Enhances the corrosion resistance of the alloy.

Tungsten (W)

Improves the hardness and wear resistance of the alloy.

Carbon (C)

Enhances the hardness and wear resistance of the alloy by forming carbides.

Characteristics:

Stellite alloy has extremely high hardness and can maintain excellent wear resistance under high friction and high stress conditions.

Due to the presence of chromium, Stellite alloy can remain stable in acidic, alkaline and oxidizing environments.

Stellite can maintain its mechanical properties and chemical stability at high temperatures, suitable for working under extreme temperature conditions.

The turbine parts manufactured by Stellite can be manufactured by equiaxed crystal casting and machining

For machined Stellite cast turbine products, suitable processing technology and tools are required to cope with their high hardness and wear resistance. Advanced CNC machining technology may be used to ensure the accuracy and efficiency of machining.

In equiaxed crystal casting, this helps to make Stellite cast turbine products have more uniform mechanical properties and good comprehensive performance. The formation of equiaxed crystals is promoted by precisely controlling various parameters in the casting process, such as temperature, cooling rate, etc. This can improve the reliability and stability of the product in use, making it better adapted to various working conditions and environments.

Application areas of Stellite

Aerospace industry: In the aerospace field, Stellite products are often used to manufacture high-temperature and high-pressure parts such as turbine blades, turbine disks, and turbine shafts because they can withstand extreme working conditions and harsh environments.

Energy industry: In the energy industry, Stellite products are often used to manufacture key components such as turbines, gas turbines, and turbine generators, which require wear resistance, corrosion resistance, and high temperature resistance.

Oil and gas industry: Stellite products play an important role in the extraction, processing, and transportation of oil and gas. For example, they are used to manufacture key wear-resistant and corrosion-resistant components such as valves, pumps, and drill bits.

Medical devices: Stellite alloys are also widely used in the field of medical devices, such as artificial heart valves, orthopedic implants, etc., because of their biocompatibility and corrosion resistance.

Automobile and shipbuilding: In automobile and shipbuilding, Stellite products are often used to manufacture high-performance engine parts, turbochargers, etc. to improve the performance and reliability of vehicles or ships.
