Yup same here. D2 and a M0sT coating. But think about it. Now many hits does it need to last? A 30yr tool will get at the most a couple thousand hits unless the price of the entire system comes down to bpipe range. Hard to justify unless your're robotic welding and cant afford the variability in spring back form the rolled edge.Any reason why you don't use heat treated D2 or similar tool steel, besides material cost? You could try coating them too. We use a company called Eifeler to coat die sections for around $13 a pound I think. Their Duplex Variantic PVD coating is top notch, we've seen 500,000+ hits on deep draw dies before having to recoat.
Also curious what the material was selected. Alot of pro's to aluminum but its also a d1ck to deepdraw w/o wrinkling. Thankfully we have simulation software to figure clamping pressures
