Weldability of High Strength Martensitic Stainles Steels
Journal of the Japan Welding Society, 1981 Influences of the conditions of weld thermal cycle and postweld heat treatment on the notch toughness, tensile properties and crack sensitivity in the HAZ of two high strength (80 kg/mm2 type and 100 kg/ mm2 type) martensitic stainless steels containing Ni, Mo, Nb and Cu were investigated by means of welding thermal cycle simulating method and the slit

Analysis of the Degradation in the Creep Strength of High-Cr Martensitic Steels
Journal of Materials Science Research, 2021 To investigate the formation process of the Z-phase, which lowers the long-term rupture strength of high-Cr martensitic steel, the creep curves of Grades T91, T92, and P92 were analyzed along with the experimental steels of 9Cr-1W and 9Cr-4W by applying an exponential law to the temperature, stress, and time parameters.
