Summary
309s is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance, high temperature strength and creep resistance. The lower nickel content of 309s improves resistance to sulphur attack at high temperatures. . 309s is recommended for applications where sensitisation, and subsequent corrosion by high temperature gases or condensates during shutdown may pose a problem.

Maximum Recommended Service
Temperature
(Oxidising Conditions)
Continuous 1100oC
Intermittent 980oC
Thermal Processing
1. Annealing. Heat between 1 050oC and 1 150oC and water quench. This treatment ensures that all carbides are in solution.
2. Stress Relieving 250-400oC for 1 hour.
3. Hot Working
Initial forging and pressure 1150-1200oC
Finishing temperature 1000oC
