Hastelloy C22 Seamless Nickel Alloy Tube ASTM B622 Seamless Round Tube

 

 

Description:

 

Alloy C22 is an improved alloy for use in a range of aggressive industrial environments. Alloy C22 has excellent resistance to pitting and crevice corrosion in oxidizing and acid chloride environments, and is practically immune to chloride stress corrosion cracking (SCC). Alloy C22 has superior weldability, and alloy C22 weld fillers are used to join other corrosion resistant alloys such as Alloy C-276 and AL-6XN® alloy.

 

Alloy 22 is nickel-base and typically contains 22% chromium, 14% molybdenum, and 3% tungsten. Iron is normally limited to less than 3%. The alloy’s high content of chromium gives it good resistance to wet corrosion by oxidizing media (e.g., nitric acid and ferric and cupric salts). Its contents of molybdenum and tungsten give the alloy resistance to wet reducing media (e.g., sulfuric and hydrochloric acids). Alloy 22 exhibits excellent resistance to corrosive attack by seawater under stagnant and flowing conditions.

 

Advantages:

 

1. Better overall corrosion resistance than Alloy C-276

 

2. Outstanding resistance to chloride pitting, crevice corrosion and stress corrosion cracking

 

3. Excellent resistance to oxidizing aqueous environments (wet chlorine and mixtures containing nitric acid and chloride ions)

 

Fabrications:

 

Although ductile enough to be formed by cold working, intermediate annealing may be necessary due to work hardening. Forging should be performed between 1750-2050° F followed by rapid cooling. Annealing can be performed at a temperature range between 2020-2150° F followed by a rapid quench. Cooling at an accelerated rate avoids the formation of detrimental phases which form between 1400-1800° F. Welding can be done by gas tungsten-arc, gas metal-arc and shielded metal-arc processes.
