MALLEABLE STAINLESS STEEL

I am looking for a stainless steel that can be worked by hand.... thickness of a foil product.... any help?

Worked by hand is subject to a lot of interpretations. One is get a bigger hammer.
Typical would be a 410 or similar SS that has been annealed and then hardened after final forming.

I suggest bright annealed 304 SS at or slightly thicker than the desired final thickness. 304 SS foil is available in thicknesses down to 0.006 mm (0.0000236 inch).

Consider 316L & 317L for better corrosion resistance, or 309 for high temperature.

SS alloys available in foil, ranked by malleability (from elongation data for annealed sheet*):
301 [60% elongation] > 205 > 304, 304L, 317L > 302, 305, 316, 316L [50%] > 309, 310, 317, 321, 347 > 201, 202 [40%] > 430 [25%] > 442 [20%].
*Ductility is somewhat lower for foil than sheet.
