What is Hastelloy?
Hastelloy is a is a type of nickel alloy that is a trademark of Haynes International, Inc.
It is an alloy with improved corrosion resistance and heat resistance, mainly by adding a large amount of molybdenum and chromium to the nickel group.
Since it is a widely used alloy group, it has become a common material in Japan.
There are types such as “Hastelloy B” and “Hastelloy C” depending on the amount of components such as molybdenum, chromium, and iron.
Hastelloys Features, Characteristics, and Properties
The main characteristics of Hastelloy are as follows.
- It is a high-performance material that surpasses titanium.
- Has more corrosion resistance and heat resistance than stainless steel
- Corrosion resistance is not easily impaired even in high temperature, non-oxidizing acid, seawater, and salt environments.
- It has excellent strength and is also used for molds, etc.
Hastelloy has excellent corrosion resistance and high mechanical strength at high temperatures, making it suitable for use in corrosive environments such as sulfuric acid, nitric acid, and chlorine, as well as in high-temperature environments.
Hastelloy also has a side as a difficult-to-cut material
On the other hand, Hastelloy material is also known as a so-called “difficult-to-cut material” that is difficult to process, and it is said that it is not suitable for structural materials because its physical strength is not high.
Hastelloy processing is said to have the following drawbacks.
- Poor machinability due to its high hardness
- Poor thermal conductivity shortens tool life due to heat generation
- It takes time to finish due to intense work hardening.
Steroy is an alloy whose main component is nickel, but it is classified into various types due to the different composition ratios of various components such as molybdenum, chromium, and iron.
The typical types and characteristics of Hastelloy are as follows.
An improved version of Hastelloy B with excellent corrosion resistance at welds.
It has high corrosion resistance, especially strong resistance to local corrosion.
It has high corrosion resistance and is resistant to corrosion even at high temperatures.
It has excellent oxidation resistance, workability, and strength in high temperature environments.
Hastelloy is used in various fields and industries because of its excellent corrosion resistance and heat resistance.
The main uses of Hastelloy are as follows.
- Equipment parts of chemical plant
- Pumps, valves and other chemical equipment parts
- Diaphragm of pressure gauge that requires corrosion resistance
- Pickling equipment
- Aircraft jet engine
- Other parts that require corrosion resistance and heat resistance in the paper industry, chemical refining, waste treatment, nuclear fuel reprocessing facilities, petrochemical industry, semiconductor manufacturing equipment, etc.

Hastelloy processing examples
TDC accepts the production of Hastelloy mirror test. Surface roughness can be guaranteed at Ra 1 nm or less. We will manufacture from 1 piece in quantity to your desired size.
Of course, we can also manufacture parts in various shapes other than test pieces.
Recently, we have received many requests for processing with long foils.
For details, see the page of “TDC Precision Mirror Foil / Long Metal Leaf Precision”.
Please contact TDC for Hastelloy processing.
At TDC, we are able to handle mirror polishing of all materials and accuracy by using the processing know-how according to the material and the polishing processing technology accumulated so far.
If you have a Hastelloy processing project that was rejected by another company, please feel free to contact TDC.
