13CRM

Modified 13 Chrome

13CRM / HP1

COMMON TRADE NAMES: 13 Chrome Modified, SM13CRM®, 13 Chrome-HP1, HP1-13CR, HP-1, Hyper 1, Hyper I

13CRM / HP1 Applicable EnvironmentsThe 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.

Applications in Upstream Oil & Gas

  • Corrosive environments containing moderate chloride content and low pH
  • High-pressure, high-temperature (HPHT), sweet (CO2) environments
  • Tubing
  • Casing

  • Base Pipe for Sand Screens
  • Expandables
  • Perforating Guns
  • Landing Joints
  • Extensions
  • Shrouds
  • Maker Joints
  • Pipe for VIT
  • Swell Packers
  • Geothermal
  • Carbon Capture and Sequestration (CCS)
