MARTENSITIC CREEP RESISTANT STEEL STRENGTHENED BY Z-PHASE FIELD OF THE INVENTION The present invention relates to martensitic or martensitic-ferritic steel alloys and in particular to creepThe creep resistance of the ferritic steels with large The creep resistance of the ferritic steels with large amounts of vanadium and chromium is significantly larger than that of simpler steels because vanadium and chrome carbides have a better temperature stability.Due to their close-packed face-centred cubic structure,the creep resistance of austenitic steels is larger.The Heat-Resistant Chromium-Molybdenum Alloy SteelsSep 13,2020 Creep resistant steels#0183;The three general types of heat resistant (creep resistant) Cr-Mo alloy steels common Cr-Mo steels,Cr-Mo-V steels,and modified Cr-Mo steels.Common Cr-Mo steels are used primarily for tube,pipe,and pressure vessels,where the allowable stresses may permit creep deformation up to about 5% over the life of the component.

Testing of Microalloyed Steel Quality under Creep
