What is Hastelloy C22 alloy strip?
Hastelloy C22 alloy (UNS N06022) strip is a nickel-chromium-molybdenum alloy material.
Its primary properties are resistance to oxidizing and non-oxidizing chemicals, and protection against pitting corrosion, crevice attack, and stress corrosion cracking.
Its high chromium content provides higher oxidation resistance than standard household media C276 alloy strip.
Like other nickel alloy strips, Hastelloy C22 alloy is highly ductile, exhibits excellent weldability, and is easily fabricated into industrial parts.
What are the characteristics of Hastelloy C276 strip?
The characteristics of Hastelloy C276 strip are as follows:
It has good oxidation resistance and can be used at temperatures up to 677 degrees Celsius.
It is resistant to seawater, steam and other corrosive environments.
Excellent performance in stress corrosion cracking tests, making it suitable for use in marine environments.
What is Hastelloy C22 strip used for?
Pharmaceutical industry accessories and welded pipes
Cellophane manufacturing industry
Chlorination system
Pesticide production line
Incineration scrubber system
Chemical processing industry in equipment such as flue gas scrubbers
Chlorination system
Pulp and paper bleaching plant
Acid washing systems and nuclear fuel reprocessing
Wastewater treatment industry
How to produce a roll of Hastelloy C22 strip?
The production process of Hastelloy C22 strip is as follows:
1. Hot rolling: The slab is evenly heated to the appropriate temperature by an electric furnace, and then it is rolled into strips.
2. Cold rolling: After hot rolling, the steel strip is cooled at room temperature and then rolled into cold-rolled steel strip. Cold rolling can improve the strength, hardness and surface finish of the strip.
3. Annealing: Annealing is a heat treatment process used to make metal more ductile and tough by heating it above the recrystallization temperature, maintaining it for a certain period of time, and then cooling it with water or oil to below the recrystallization temperature.
4. Packaging: After annealing, the strips are packed into small rolls or rolls, large rolls or coils and straight rods according to different products to prevent rust during transportation.
How to choose the right Hastelloy C22 strip supplier from China?
If you want to buy Hastelloy C22 alloy strip for industrial use, you should know that there are many suppliers and manufacturers that produce alloy C22 strip and supply it to many industries such as heat exchangers or chemical industry.
But in fact, not all suppliers have the ability to produce high-quality products, and some just choose cheap materials but with high prices, which is not a good choice for users.
Here is a quick guide on how to choose a good Hastelloy C22 strip supplier.
First, you should ask the manufacturer if they can do the inspection themselves before delivery. Most large factories have their own inspection team, and they will strictly inspect all goods before delivery.
Second, you should ask if they use 100% pure raw materials to produce your goods, because some suppliers use recycled raw materials or mixed raw materials that may cause problems during use.
Third, it is best to visit their factory and check the production line and warehouse yourself. It would be great if you could check their production process and production equipment. Because it is very important for you to understand how they control the quality from process to delivery.
