Thermocouple Sheath Comparison
316SS (stainless steel): This is the most common sheath material. It is relatively corrosion resistant and is cost effective.
304SS: This sheath is not as corrosion resistant as 316SS. The cost difference between 316SS and 304SS is nominal.
Inconel (registered trademark) 600: This material is recommended for highly corrosive environments.
