PRODUCT PARAMETERS
Overview
HASTELLOY C-22HS alloy is the premier nickel-chromium-molybdenum, corrosion-resistant material for oil and gas industry use. It is s one of the well-known and well-proven nickelchromium-molybdenum materials, the chief attributes of which are resistance to both oxidizing and non-oxidizing chemicals. Hastelloy C22 provides resistance to general corrosion, pitting, crevice corrosion, intergranular attack, and stress corrosion cracking. Hastelloy C22 contains chromium, molybdenum, tungsten, and iron which makes the alloy resistant to corrosion in stagnant or flowing seawater. The alloy is formed by gas tungsten-arc, gas metal-arc, and shielded metal-arc processes.
Like other nickel alloys, HASTELLOY C-22 alloy is very ductile, exhibits excellent weldability, and is easily fabricated into industrial components. It is available in the form of plates,sheets, strips, billets, bars, wires, pipes, tubes, and covered electrodes.

Corrosion Resistance
Hastelloy C 22 alloy suit for many kinds of chemical process industry which contain the oxidizing medium and reductant. High molybdenum and chromium content make it can resist the chloride corrosion, and tungsten make this corrosion resistance better. HY HC22 is one of a few material that can resist the corrosion of moist chlorine, hypochlorite and chlorine dioxide, this alloyhave prominent corrosion resistanceto high concentration chlorate( iron chloride and copper chloride).
Heat Treatment
