CO50 alloy is designed for the most demanding environments, providing the durability your stainless steel pipes and stainless steel pipe fittings need when faced with severe challenges.
What is CO50 Alloy: A Super Alloy with High Performance
CO50 alloy is a special cobalt-based alloy renowned for its exceptional hardness and excellent wear resistance. It is composed of cobalt, chromium and tungsten, which give it high strength and provide excellent thermal stability. When nickel-based alloys and high-quality stainless steel fail to meet requirements, it becomes the material of choice.
Main Advantages of CO50 alloy
CO50 alloy boasts extremely high hardness, effectively preventing galling and seizing. It maintains a long service life even under abrasive and high-friction conditions.
This alloy maintains its mechanical strength under extreme temperatures, reliably withstanding high-temperature environments while resisting creep deformation.
It resists various corrosive media, including strong acids and chloride-rich environments. It performs well in both oxidising and reducing media.
It maintains its performance at high temperatures without a rapid decline in strength. This makes it well-suited for high-temperature applications.

Applications of CO50 Alloy in Pipelines and Related Systems
- Valve Trims: CO50 alloy is wear resistant and available for valve seats and plugs.
- Pump Sleeves and Bearings: CO50 alloy has anti-friction and anti-seizing properties, extending the service life of pumps operating in harsh environments.
- High-temperature Piping: Components in furnaces and kilns require extremely high strength and can be used for critical stainless steel piping components.
- High-Wear Surfaces: It can be applied as a hardfacing layer to protect vulnerable components.
Sourcing and Processing of CO50 Alloy
A complete Material Test Report (MTR) is required. It verifies the precise composition of the alloy and ensures its performance.
Work with specialized suppliers of stainless steel pipe and fittings. They understand these alloy steels and can ensure proper fabrication and quality control,and are ISO 9001 and CE-PED certified.
This alloy is difficult to machine and requires special tools. Specific welding techniques are essential to ensure the integrity of the weld.
This alloy is expensive, so it is important to assess whether the product has a longer service life. This can justify its higher initial cost.
