The Therma range stainless steels are designed for applications with service temperatures above 550 °C/1020 °F. These products give you better oxidation and high temperature corrosion resistance as well as long-term creep resistance.Due to the loading and to the temperature, these devices are submitted to creep under complex atmosphere with low oxygen partial pressure content. Unusual damages and high creep strain rates have been reported on components made of 310S Stainless Steel. Therefore, the mechanical behavior at high temperature of this alloy was investigated. Many dataAlloy 321 stainless steel plate is also advantageous for high temperature service because of its good mechanical properties. Alloy 321 stainless steel plate offers higher creep and stress rupture properties than Alloy 304 and, particularly, Alloy 304L, which might also be considered for exposures where sensitization and intergranular corrosion .
Thermo-mechanical treatments (TMT) at different rolling deformation temperatures were utilized to process a martensitic heat-resistant stainless steel 403Nb containing 12 wt pct Cr and small additions of Nb and V. Microstructures and mechanical properties at room and elevated temperatures were characterized by scanning electron microscopy, transmission . In addition to creep and fatigue, oxidation is unavoidable for alloys exposed to high-temperature oxidizing environments. For heat-resistant stainless steel, which is utilized in the production of reheater tubes, superheaters, turbine blades, and so on, breakaway oxidation is one of the primary causes of component failure at elevated temperatures [11].
During the continuous casting of 430 ferritic stainless steel, the broadening phenomenon and bulging deformation are considered a high-temperature creep. This study investigates 430 ferritic stainless steel by conducting high-temperature uniaxial creep experiments under the temperatures of 0.4-0.5 Tm and stresses of 32.5-85 MPa. After creep .
Since the first introduction of the high-entropy alloys (HEAs) [1, 2], part of characteristics of the alloys that have attracted the most attention has been solid solution strengthening due to lattice distortion and sluggish diffusion both of which would contribute to high temperature creep resistance and, therefore, high temperature structural application was . Secondary-stage creep strain/Δln t from 0.1 to 4 x 10 4 minutes for annealed austenitic stainless steel alloys 304HN, 310, and 316 plotted as a function of normalized applied stress.
