Maybe either he or I is not communicating correctly. Hard to say. He was pretty short about the subject when we last spoke. Q: how do you achieve a particular/desired hardness when cold working (i.e.- measurable between 1/4, 1/2, etc.)
As for the calculations, I have none as yet but really...
Wow, I just spoke to my potential spring guy who will make this in production and he freaked out at the concept of going with 17-7. He believes 301 spring tempered 1/4 to 1/2 hard will work fine. He mentioned if it doesn't, he'll but annealed 301 and trat as required when done to accomplish the...
Thanks to the both of you for your speedy response. It appears that my best course is to go with 17-7PH, laser cut-it to size/add features, form (.008 inside Bend radii) and heat treat accordingly. My only and last concern is how to determine the actual hardness required to become "springy" and...
Good Morning---
I'm in need of some advice about material selection for a small sheet metal latch I'm defining for fabrication. This is a smal latch with 3 bends, one bend past 90°. I need to define a S/S material that allows this item to be formed, w/o cracking and still remain as a spring...
