Also known as, 4140 PH (pre hardened) HRC 27-32
My regional distributor historically sold resulfurized, round bar. Great tool life and surface finish. Distributor has switched to a mill suppling product with no free machining additive. Part quality is suffering. Struck out finding the former product elsewhere. Appealing for a domestic source for 4140HT with sulfur or lead additive. Bar size to 12"
