COMMON TRADE NAMES: 15Cr, Ultra Hyper Chrome, JFE-UHP™-15CR, UHP™
15 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.
Super 15 Chrome, grade 125, is not recommended for sour service.
