55NiCrMoV 7 /AISI: 6 F 3
Delivery Method : Normalized, annealed 180-230HB
380-420HB (40-44 HRC) as pre-hardened
Uses : It is a hot work tool steel that can harden in oil and air and has a high toughness. It is widely used in hydraulic and mechanical forging dies in which iron and steel products are formed by pounding, as rammers, anvil and hammers, as a support element in the tooling systems of extrusion presses, in various stamps, and in their stamps.
