its my second male here is specification of tht leaf spring.that u asked me
jis japnese standard sup-9, its composition is carbon .52 to .60%, mn is ..78 
cromium is 0.78% more or less and cu is 0.35 max, so sugges me .

MadSci admin tentative rewrite -

This is a repeat of my earlier question.  As requested, I have added 
specifications for the leaf spring.  The spring is a jis Japanese standard sup-
9.  The composition of the spring is as follows:

    Carbon     0.52 to 0.60 %
    Manganese  0.78 %
    Cromium    0.78 % (more or less ?)
    Copper     0.35 % (maximum)
    Iron       (assume the remainder is iron)

So, how might the fatigue strength of such a leaf spring be increased.
