22 Chrome (UNS S31803), also referred to as 2205 Duplex or 22Cr, is a cold hardened duplex stainless steel intended for corrosion resistance in sweet (CO2) and mildly sour (H2S) environments with moderate chloride content, requiring high strength up to 400°F.
22Cr offers improved mechanical properties and increased resistance to the effects of CO2 , chlorides, pH, and temperatures when compared with Super 13 Chrome. The higher strength and temperature resistance, relative to Super 13 Chrome, allow it to be used in deeper wells with high-pressure and high-temperature (HPHT) conditions, as downhole tubular components, packers, and other subsurface equipment. All environmental factors, including H2S, CO2 , temperature, pH, and chloride concentration, should be considered before final material selection.
This alloy is classified in MR0175/ISO15156 as a duplex stainless steel having a Pitting Resistance Equivalent Number (PREN) ≤40 and is suitable for H2S partial pressure ≤0.3 psi.
