摘　　要：本文简述了淬火剂SST201的基本特性,并对其冷却特性进行了探讨。结果表明:SST201的冷却能力随其浓度增大,温度升高,重复使用次数增多而降低,并揭示了该介质在冷却金属时能在金属表面形成一层聚合物隔离膜,此膜能避免因零件的几何形态的差异造成的冷却不均匀现象,有效地防止开裂与变形。This paper describde the basic chracteristics of a new quenchant SST201 ,and the cooling chracteristics of the quenchant was inrestigated the resnlts shou that the cooling ability of the quenchant will dessend as the increase of It's concentration temperature and service frequency and a film of bdgmev will form on the surfale of metal in the cooling process. Which can avoid the heterogeneous bhenomenon. rcalated to difference from the geometric shape of workpieces thus the quenching distortion and craccs can be prevented.
