Hi,
I've got a project where mild steel is not springy enough; Ideally I'd like to get a steel that has a yield point 2~3 times as high.
two q's;
1) Is there a cheap steel that meets this spec ? 2) I'm having trouble reconciling hardness specs like rockwell with yield point and elastic modulus - (all I care about). Can someone cite a reference that explains how hardness and temper (yield point) relate. 3) In fact I only need a fraction of the part to have this higher yield point. Is there a home DIY process for heat treating steel for this characteristic?Thanks,
