Low carbon supermartensitic 13%Cr steels with 4-6%Ni and 0-2.5%Mo additions have been developed from type AISI 420 steels for applications in the oil industry. They offer significantly better weldability, improved general corrosion resistance, particularly in carbon dioxide environments, and some grades exhibit improved resistance to sulphide stress corrosion cracking. In this paper results of detailed investigations on a 13Cr-6Ni-2.5Mo-Ti steel after quenching and double tempering are presented. Microstructural studies were carried out using optical microscopy, transmission electron microscopy and X-ray diffractometry. The results prove that formation of austenite during tempering at both 690 and 620 degrees centigrade is accompanied by intensive precipitation of Fe-Mo Laves phase particles.
