Correct Stainless Steel to use

Correct Stainless Steel to use

Correct Stainless Steel to use

(OP)
Guys,

I have a part that I'm trying to make out of 304 stainless steel.  The problem I'm having is I need to obtain a flatness and parallelism of .0008 of an inch.  Everytime I cut this material it tends to warp.  My question is, Is there a stress relief process that will enable me to hold this close tolerence on 304 stainless, or what is a more stable stainless that would be easier to keep flat?

Thanks,

Doyle

RE: Correct Stainless Steel to use

I don't know if you ever solved your problem-I just came across your request. I would get the stainless blank stretcher leveled to eliminate residual stress and get initial flatness and then laser cut the shape you want. This gives high precision without cutting distortion.
