Now a days there are many investigations on the S curves of steels, and it is generally recognized that mechanical properties of Bainite structure are suitable for spring.
We examined the effect of austempering process for several kinds of spring steels and investigated whether this process is suitable practically or not.
The results obtained are summerized as follows:-
(1) Suitable size of steel for austempering process may be very small, especially for carbon steel.
(2) In carbon steel, Eutectoid composition may be suitable for austempering process.
(3) In Si-Mn steel, the effect of austempering process may be better than in carbon steel.
(4) We recognized that Cr-steel may be unsuitable for this process.
