Abstract: Based on experience practice used PAG for many years, typical problems appearing in production field of heat treatment on using PAG (Poly alkylene glycol) quenchant were analyzed, such as pseudo concentration, big changes of cooling characteristic, corrosion of quenching parts, corruption and smelliness of quenchant, foaming of quenchant, etc. The corresponding solutions and countermeasures were put forward.

Key words: PAG polymer quenchant, common problems, analysis and countermeasures
