The CPM blades come in from the vendor at 60/61 but after a couple hundred cycles in and out of the production oven between 500-1000, they measure 43-48 on our rockwell tester.
Yeah we use D2 pretty regularly in our punches and dies and typically temper at 400 to get 59/60 Rc. That's why I want to switch to D2 from CPM 10V. The CPM isn't holding the hardness and cutting edge that I think D2 would give us after basically tempering it over and over again in the...
Thanks EdStainless. I should have said SS and nitinol for that temp range but it doesn't seem like the D2 would pose a problem. With the D2 having already been heated to 1850 for hardening, I would think anything that would happen already did but I just wanted to make sure.
Is there any danger with putting D2 parts in an oven heated to between 500-1000F with medical stainless steel product? I've been told the D2 could outgas chromium but I haven't found anything to confirm that.
