ASTM B474

Hastelloy® C-22

· UNS Number N06022

· Other common names: Alloy C22

This specification covers electric fusion welded pipe suitable for high-temperature or corrosive service. The pipes are designated into five classes namely Class 1, Class 2, Class 3, Class 4 and Class 5, according to how they are to be welded. The joints shall be full penetration double-welded or single-welded butt joints employing fusion welding processes. The furnished pipe shall undergo heat treatment and a chemical analysis shall be employed for both plate and weld. Each pipe shall be subjected to transverse tension test, transverse guided weld bend test and hydrostatic pressure test.

Hastelloy C22, also known as alloy 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.

Fabrication of Hastelloy C-22

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.

6.Hot-Rolling Steel

Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature

over 1700° F), which is above the steel’s recrystallization temperature. When steel is above the

recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger

sizes. Hot rolled steel is typically cheaper than cold rolled steel due to the fact that it is often manufactured

without any delays in the process, and therefore the reheating of the steel is not required (as it is with cold

rolled). When the steel cools off it will shrink slightly thus giving less control on the size and shape of the

finished product when compared to cold rolled.

Uses: Hot rolled products like hot rolled steel bars are used in the welding and construction trades to make

railroad tracks and I-beams, for example. Hot rolled steel is used in situations where precise shapes and

tolerances are not required.
