Characteristics
  • These are austenitic chromium-nickel stainless steels with excellent oxidation resistance and capable of resisting temperatures up to 1150˚C in continuous service. They also provide good resistance to carburizing environments. T-310S is simply a low carbon modification which is to be preferred in welded construction.
Typical Applications
  • Furnace parts, carburizing boxes, heat treating trays, oven linings, heat exchangers, gas turbine parts, jet engine rings.
Corrosion and Heat Resistance
  • Primarily designed for heat resistance, T-310/T-310S are good to 1150℃ for continuous service and offer resistance to 1038℃ for intermittent service. They provide good resistance to thermal fatigue and cyclic heating. Excellent corrosion resistance at normal temperatures, with good resistance to carburizing and reducing environments at high temperatures.
