I would like to ask the experts: For thermocouple sleeves made of TP321 and TP347SS, what are the differences between these two materials in terms of operating conditions such as the medium, temperature, and pressure?

Personally, I don’t think there’s much difference!

In high-temperature and strongly oxidizing environments of 427–816°C, 347 is more resistant to uniform corrosion than 321. Moreover, 347 is more resistant to intergranular corrosion than 321.

I’ve learned something new, thank you! Haha. So does 347 have better corrosion resistance than 321 and 316?
