HASTELLOY® C22 Nickel Alloy
A nickel-based superalloy designed to provide high corrosion resistance in aggressive chemical environments, chlorides, strong acids and critical industrial processes.
A nickel alloy for environments where corrosion does not forgive
HASTELLOY® C22 is used in applications where chemical resistance, material stability and component durability are decisive factors.
HASTELLOY® C22 is a high-performance nickel alloy designed to operate in extremely corrosive industrial environments. Its composition with chromium, molybdenum and tungsten improves resistance to oxidizing media, reducing environments and chloride solutions.
This alloy is used when conventional stainless steels do not provide sufficient protection and when corrosion-related downtime can generate high costs, safety risks or loss of production continuity.
In machining, HASTELLOY® C22 requires experience, rigidity, proper cooling and high-performance tools to maintain dimensional accuracy and a good surface finish.

Increases the service life of parts exposed to corrosive media, salts, acids and critical processes.
Reduced maintenance
Helps minimize replacements, repairs and downtime associated with premature corrosion.
Technical traceability
Ideal for projects requiring certification, quality control and material documentation.
A demanding alloy that requires process control
HASTELLOY® C22 machining should be carried out with stable parameters, suitable tools, efficient cooling and a strategy designed to avoid surface work-hardening, vibration and accelerated tool wear.
Recommended to maintain stability, precision and tool life during cutting.
Help limit work-hardening and improve surface finish quality.
Essential to control temperature, chip evacuation and tool wear.
Key in the machine, clamping and workpiece to avoid vibration and dimensional deviation.
The strategy must be adapted to the drawing, geometry, tolerances, batch size and final application.
