Abstract: Characteristics of water-soluble PVP polymer quenchant KR9180 was introduced, and the quenching teston spring rod by using KR9180 with 15% concentration was conducted. The results show that the hardness, metallographic structure and fatigue properties of spring rod can meet the technical requirements if the oil quenching is replaced by 15% KR9180 water-soluble quenchant.

Key words: spring rod, water-soluble quenchant of KR9180, process test
