Sprayed, welded or cast alloys for high heat
I have an application for thermowells which need to withstand temperatures of 1400 Deg Celsius. Which alloys would perform here?

I need an alloy which can be PTA welded or HVOF sprayed. Alternatively, something that can be investment cast would also be useful.

What do you mean the coating has to withstand 1400C? Are you trying to prevent corrosion, erosion, etc at that temperature? What is the atmosphere where the thermocouple will work? That will make a difference in the coating you can use.

Hi,
I had same problem but my thermowell worked at 800 C. I tried to coat inconnel 625, and stellite 6 with HVOF. BUT we can't get good results. And we welded stellite. The results grown up
