Hardening and brazing 316L stainless??

[jawnn]

Is it possible to harden 316 stainless tubing by tapping it with a small hammer? or sand blasting?


How does it Braze?

It can be "work hardened", but I've only done quite by accident while trying to trash cutting tools.

I've never tried to deliberately harden it, but one clue about whether or not it's done in any way is....knives.

You rarely if ever see 316SS used as knife blades because it's either too expensive to harden it or just not doable. If there's a material out there that can be hardened, look pretty (316 shines up nice) and resist corrosion, the knifemakers are all over it.

As for brazing, I defer to others. I imagine it will braze fine though I know TIG welding 316 comes out AWESOME if done right.

300 series stainless can't be hardened using heat. It can be surface hardened by shot peening, but the effect won't go very deep.

It can be readily silver soldered.
