Stellite is a cobalt-chromium superalloy family that’s non-magnetic and corrosion-resistant. It can be used in various applications, including manufacturing and engineering.
However, this material has a shallow machinability index, which makes it difficult to cut. To address this, researchers conducted an experimental study on economically rational cutting parameters for machining Stellite using coated carbide inserts.
Know Your Material
The first step in machining Stellite is to know your material. This includes understanding the chemical composition of the alloy, its machinability characteristics, and how it will react to your environment.
Satellites are a family of cobalt-chromium alloys that also contain tungsten and molybdenum. They are known for their high resistance to corrosion and oxidation, as well as their durability at elevated temperatures.
Stellite 6 manufactures parts for industrial applications, including the locking lugs and shoulders of Voere Titan II rifle barrels. It is also used in artificial hip joints and dental prosthetics. In addition, the material is more resistant to the abrasive acids found in some woods than swaged saw steel. This knowledge of your materials will allow you to optimize machining conditions, resulting in higher-quality products.
Know Your Tool
Stellite is a family of entirely non-magnetic, corrosion-resistant cobalt alloys. Each alloy has specific characteristics and combinations of other metals to maximize wear resistance, oxidation resistance, or ability to withstand extreme temperatures.
Stellites can be joined together using stellite welding, where the surfaces of the two pieces of metal are cleaned and pre-heated before an arc or laser is used to melt them together. The weld is then cooled and hardened before it can be used.
When cutting Stellite, knowing your machining tool and setting it up for success is essential. Using proper feed rate, radial engagement, and cutting force will help reduce heat generation, which can cause work-hardening and surface roughness. An analysis of the variance model was also created to forecast surface roughness based on the different cutting parameters.
Know Your Environment
Stellite alloys are non-magnetic, resistant to corrosion and oxidation, and highly wear-resistant. They are also used in medical devices such as surgical tools, artificial hip and bone replacements, and dental prostheses.
They are not easily machined because of their high melting point and hardness. Often, they are welded instead. This can be done manually or by using a welding robot.
This study evaluated the machinability of cladded Stellite 6 on steel substrate using different process parameters. The results show that process variables significantly affect surface roughness and that these factors should be considered to avoid surface damage during stellite machining. This could increase the life of the equipment. This is especially important for the petrochemical and oil industries to maximize productivity and reduce maintenance costs.
Know Your Part
Stellite alloys have exceptional resistance to corrosion, oxidation, and wear and can be used in highly corrosive environments. They also have good resistance to high temperatures. Stellite is a cobalt-chromium superalloy with complex carbides that makes it very strong. It is commonly found in saw teeth, hard-facing, and acid-resistant machine parts.
Stellite welding is a process that allows two different metals to be joined together in a permanent, solid weld without the use of filler materials. The resulting weld is reliable and can withstand high temperatures and stress without compromising its integrity.

Stellites are cobalt (Co)-based superalloys capable of withstanding extreme temperatures, forces, and stresses. These properties make them incredibly useful for critical components operating in harsh environments. However, they are difficult to machine, which increases lead times and costs.
Knowing the machining parameters that will result in the best surface quality is essential. One method of achieving this is by using HVOF. This process sprays high-velocity, low-pressure cobalt stellite alloy powder jets onto steel substrates. This provides the desired material characteristics without the high cost of a solid satellite.
