316 Stainless Steel for Heat Exchangers

1. What is 316's fatigue strength? Approximately 190 MPa at 10⁷ cycles (room temperature).

2. Does temperature affect 316's fatigue resistance? Strength decreases above 500°C but remains stable for cyclic service.

3. Can 316 withstand thermal cycling fatigue? Yes, it resists crack formation from repeated heating and cooling.

4. Is 316 suitable for high-stress rotating components? Yes, for moderate-speed shafts and gears in corrosive environments.

5. How to improve 316's fatigue resistance? Polishing surfaces to remove defects and reduce stress concentrations.
