Hello All,

I have a TCC coating applied to carbon steel inside a vessel. The vessel has the heads welded on and has been PWHT at a hold temp. of 600 DegC. The TCC coating has powdered and started delaminating. Particularly in the nozzle transition areas.
Does anyone have feedback for this failure please?
