If you are trying to cut bolts made out of Type 316 (or 304) stainless, it work hardens, which is why it's tough to do.

gettin close. All austenitic stainless steels (ie 300 series) work harden if subjected to cold working whether it be grinding, cold forming or cutting. So the secret to cutting them is to have a sharp cutting tool, to cut steadily under pressure and above all to avoid any rubbing type contact. Worst possible tool is a blunt drill or hacksaw which will harden up the workpiece rather than cut it.

If the material is already hard because it has been (say ) cold extruded, then the only practical way is to anneal it at up to 1050 deg C but you risk subsequent corrosion problems if you try this with a typical domestic blow lamp.

the 400 series stainless steels (knife blades and razor blades) are completely different but unlikely to find their way onto your bike.

Lucky enough to have access to carbide tooling, handy where stainless is concerned !
