Martensitic Stainless: 17CR

17 Chrome is a quenched and tempered martensitic-ferritic stainless steel intended for high pressure, high temperature (HPHT) wells where high strength OCTG is required. In addition to extending the temperature range, 17 Chrome provides improved performance compared to the 13 Chrome Alloys in chloride and sweet (CO2) environments. 17Cr-125 is not recommended for sour service.
