Hastelloy S has good thermal stability, a low thermal expansion coefficient below 1093°C and excellent oxidation resistance. Has good high temperature strength and thermal fatigue resistance. It can still maintain its strength and ductility after aging treatment at 427-871°C. Hastelloy S is particularly suitable for hydronic heating environments.
