Project Description
API L80 Modified 13 Chrome Corrosion Resistant Steel Pipe for Oilfield
The Modified 13 Chrome alloys, 13CRM & HP-1, are quenched and tempered martensitic stainless steels intended for corrosion resistance in sweet (CO2) environments containing chlorides up to 350°F. Relative to 13 Chrome, the Modified 13 Chromes provide increased strength and corrosion resistance at higher temperatures and chloride concentrations. Their higher strength and temperature resistance allow for use in deeper wells with higher pressure and temperatures, as downhole tubular components, packers, and other subsurface equipment.
While Modified 13 Chrome grades provide improved resistance to pitting corrosion relative to 13Cr L80, they are vulnerable to localized corrosion, SCC (stress corrosion cracking), and SSC (Sulfide Stress Cracking), so higher grades should be utilized for sour service or high chloride environments.
