BS BA 2
Air hardening cold work steel, good machinability, high wear resistance and improved toughness (reduced occurence of hard carbides with about 5 % chromium compared to 12 % chromium in ledeburites AISI/SAE D2, AISI/SAE D6, AISI/SAE D3). Good dimensional stability during heat treatment and easily repairable through welding. Working hardness: 58-62 HRC.
Blanking tools, stamping tools, dies, punches, trimming tools, cutting tools, thread rolling tools, thread rolling dies, shear knives, circular shear knives, cold pilger mandrels, cold stamping tools, plastic moulds.
