Hardening the steel baskets (or any of the quench & temper steels, including 
tool steels), does not make it any stronger as far as resisting bend.  The 
amount that a piece of steel will deflect or bend under weight is called the 
Modulus or Modulus of Elasticity, or Modulus of Rigidity, and as strange as 
it sounds, is the same for a piece of annealed or fully hardened steel.  A 3 
ft. long bar of 1/2 inch diameter drill rod held on one end in a vice, and a 
5# weight hung on the other end, would bend or deflect the bar the same 
amount if the drill rod was annealed (Rockwell C 24) as you purchased it or 
Rockwell C 62 after hardening.  It will take a "set" with less weight as the 
yield strength is lower on the soft steel.
