Stainless steel "full hard" but in a roll? 1

[antknee]

Hi,

I need some stainless steel that is 0.2mm thick that doesn't deform. I have found some stainless 304 that is "full hard" but it comes in a roll so I'm thinking it must bend because it'll come in a can. I just don't know what I'm googling for any more. I thought "full hard" meant stainless would not bend? What do I need to buy? Is there a particular term such as low ductility that I need to look for? I basically need a sheet of 0.2mm stainless that won't deform without a lot of trying, it doesn't necessarily have to be 304. Thanks. Antknee.

AntKnee read the previous posts closer- if you want something less deformable and want 0.2 mm thickness without corrugations then you want something other than standard alloy 304 stainless steel- no matter what hardness condition.

According out of common alloys

Cr-Mo steels Cr 5% - 9%
is the stiffest.

That is an interesting comparison but it has to be 0.2mm stainless steel. I'm going to see if I can get some especially cold rolled for me, I've asked for a hardness of Rockwell C80-100 or 4,000N/mm2 from a couple of companies. I have a feeling I won't get any reply...

Who do you think could roll me some?

Thanks,

Ant.

You are not going to get any steel in those hardness ranges. You are up in the range of ceramics, getting close to diamond.

I was wondering about that, I'll ask for something lower next time or perhaps ask what is the highest hardness they could get to in 0.2mm stainless. I know that 2000N/mm2 or Rockwell C50 are common for full hard, so there must be some more if I ask the right company, maybe i'll ask for 2500 or 3000 N/mm2 i'm not sure. Thanks, Ant.
