What is Hastelloy C22?
Hastelloy C22 is a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting， crevice corrosion and stress corrosion cracking. The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media. This nickel steel alloy also has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions. Other corrosives Hastelloy C-22 has resistance to are oxidizing acid chlorides， wet chlorine， formic and acetic acids， ferric and cupric chlorides， sea water， brine and many mixed or contaminated chemical solutions， both organic and inorganic.
This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. This is beneficial in multi- purpose plants where such “upset” conditions occur frequently. This nickel alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone， thus making it suitable for most chemical process applications in the as-welded condition. 哈氏合金 C22 can't be used in service temperatures above 1250° F due to the formation of detrimental phases which form above this temperature.
Characteristics of Hastelloy C22:
- 抗点蚀、缝隙腐蚀和应力腐蚀开裂
- 对还原性和氧化性介质都有出色的耐受性
- 对氧化性水介质具有出色的耐受性
- 具有出色的耐各种化学加工环境的能力，包括铁酸、醋酸酐等强氧化剂以及海水和盐水溶液
- 防止在焊接热影响区形成晶界析出物
- 出色的焊接性
