Stainless Steel Cold Rolling
I need strip or foil in a gauge and flatness a mill coil will not hold. Who rerolls it, and how thin can they go?
What it is
Reducing sheet or strip below recrystallization temperature to achieve tighter gauge control, better surface finish and higher strength, followed by annealing.

ATI Inc. Reportedspecialty coil below 0.0005 in thick; slit width below 0.075 in
Stainless across austenitic, ferritic, martensitic, duplex, precipitation-hardening, superaustenitic and superferritic classes rolled to fine gauge. Cold rolling is recorded from published gauge rather than a named process: ATI states specialty coil below 0.0005 in thickness, and no hot mill produces gauge that fine. Held at medium on that reasoning.

Cold rolling of stainless flat product. Recorded from the product range rather than a named process step: flat-rolled steel is by definition rolled, and this is an integrated producer rather than a distributor. Held at medium for that reason.
