超冷處理 Cryogenic Treatment
可將刀把內部殘留之沃斯田鐵 (AUSTENITE) 變成麻田散鐵 (MARTENSITE)，其可變態之組織可 經過超冷處理後金相圖
達97~98%。右圖為兩片同材質，但不同熱處理之金相圖。 Constitution diagram after
cryogenic treatment
刀把如經深冷處理, 其壽命及穩定度遠超過未處理之材質。
本公司產品經深冷處理之產品有 HY,CR,PFC 等。
To eliminate the stress after quenching and machining,and also prevent thermal shock. The
austenite almost fully transforms into martensite ( around 97％~98％ ).Cryogenic treatment 未經過超冷處理之金相圖
makes tool holders better wear resistance,no deformation,and no change in hardness over time Constitution diagram without
cryogenic treatment
to further improve the stability and life of tool holders.
Tool holders with cryogenic treatment are HY, CR, PFC etc.
