what do you think about chromium carbide cladding? can I use it for wear and erosion resistant in FCCU reactor and cyclones and transfer line?
Your regards
Hi sorousheti,
There are many good wear-resistant and corrosion-resistant alloys, also with chromium carbides, that have been developed specifically for cladding: Stellites (eg, Stellite 6, Stellite 12) Tribaloys (eg, T-400, T-700, T-800) and among others. However, the higher the hardness, the difficult is welding. You need for this hard materials preheating sometimes up to 600°C and subsequent annealing > 650°C.
For large containers and pipes have to compromise and choose something softer materials that are easier to cladding. For such objects is often Inconel 625 used.
