    STEEL - AISI A8Mod (Bohler Chipper, Uddeholm Viking)

    General Uddeholm Viking is a oil-air-vacuum-hardening steel which is characterized by: • good dimensional stability during heat treatment • good machinability and grindability • excellent combination of toughness and wear resistance • normal hardness in the range 52–58 HRC • ideal for surface coating (CVD, PVD) Exaggerated sketch of a typical punch and die in action. The chemical composition of Uddeholm Viking gives a hardness potential of 58 HRC with compressive strength and wear resistance accordingly. The small amount of primary carbides means a high chipping resistance and with 8 % chromium follows a very good hardenability and also a fairly good resistance to corrosion.
