【摘要】 介绍了28MnSiB,60Si2Mn两种弹簧钢应用水溶性聚乙二醇(PAG)类淬火介质进行淬火的情况。适当调整水溶液的浓度,可以获得不同的冷却速度。对于28MnSiB和60Si2Mn钢,淬火最佳浓度分别为10%和12%,并有较小的变形、开裂倾向。更多还原

【Abstract】 The quenching of Spring steel 28MnSiB and 60Si2Mn used PAG Solution has been investigated. The cooling rate can be altered by controlling concentration of PAG. The optimum concentration for 28MnSiB and 60Si2Mn steel which were determined experimentally were 10% and 12% respectively. The tendency to distortion and cracking were decreased.更多还原
