Project Description
API 17 Chrome Corrosion Resistance Steel Pipe For Oilfield
17 Chrome is a quenched and tempered martensitic-ferritic stainless steel intended for corrosion resistance in sweet (CO2) environments with moderate chloride content, requiring high strength up to 400°F. 17 Chrome offers improved mechanical properties and increased resistance to the effects of CO2 , chlorides, pH, and temperatures when compared with standard 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.
17 Chrome may be considered as a cost-effective alternative to duplex stainless steels such as 22 Chrome for higher pressure and temperature HPHT conditions. However, all environmental factors, including H2S, CO2 , temperature, pH, and chloride concentration, should be considered before final material selection. 17 Chrome is not recommended for sour service.
