@metengr the spectroscopic gun is extremely accurate (and is calibrated) in identifying the chemical composition which I've listed in the first post. If you know the commercial name, feel free to chime in with your gems of knowledge. Thank you! @EdStainless I don't have the hardness of the...

About carbon content, I'm just guessing, it cannot be higher than 0.1% since if you add all the contents it sums to 99.9 Machinability, it has broken the inserts which are specially made for 304 at just 80m/min Vc. Those inserts go at 200m/min in 304. Its gummy but extremely tough. The inserts...

hi Folks, I'm trying to identify this stainless steel alloy. It's extremely tough to machine: The spectroscope says so: Fe: 73.10 Cr: 13.19 Ni: 9.79 Mn: 1.93 Mo: 0.88 V : 0.36 Si: 0.28 Cu: 0.27 Co: 0.10 Any help will be highly appreciated! Thanks, N

Thanks for your feedback. So if I understand correctly, its better to soak the entire mold in hot circulating air, w.r.t. even heating locally? How about flat heating elements with aluminum sheets on them, attached on the mold (conforming to the mold)? I would like to do away with...

Hi All, Just wondering, has anyone tried heating of molds by wiring carbon filaments that are already laid into the mold as structural reinforcements of the mold. If so, what are the gotcha's? What are parameters that one would need? Would this save energy and give me a Greener part ;-) ...
