14 Common Defects of Heat Treatment and Their Remedies

14 Common Defects of Heat Treatment and Their Remedies

Apr 03, 2020 In the case of the salt bath or muffle furnace, preheating is not necessarily due to uniform heating of steel. Quenching Media; The purpose of hardening treatment is to generate such severe cooling that Pearlitic transformation gets avoided and all austenite converts into a martensitic structure.

Porcelain filters are cleaned by placing them in a muffle furnace and raising the temperatures to a red heat. This burns the organic matter in the pores and restores the filters to their original condition. Filters of the Berkefeld and Mandler types are cleaned by placing the cylinders in a special metal holder connected to a faucet.
