D2. Wysokowęglowa, wysokostopowa stal narzędziowa, która ze względu na swą odporność na korozję zaliczana jest do klasy pół-nierdzewnych (semi-stainless). Dzięki stosunkowo wysokiej domieszce wanadu i dużej ilości chromu, jest ona bardzo odporna na ścieranie i tnie agresywnie.

Nice work Chris and like the runout is zero, pretty amazing. It looks like the marks are the result from hard jaws or the part was dropped. Could the deep indent be filled out by hard silver solder and then machined by CBN insert as you said they are very brittle.
