CR7V-L Steel

CR7V-L Steel

Steel name: CR7V-L
Diagram No.: 2045
Chemical composition in weight %: 0.42% C, 0.50% Si, 0.40% Mn, 6.50% Cr, 1.30% Mo, 0.80% V
Steel group: Hot and cold work tool steels
Properties: CR7V-L is a special high Cr-alloyed steel with Mo and V additives and is characterized by excellent high temperature wear resistance with very high temperature strength and good thermal fatigue resistance. The steel is ideal for use in hot and cold work applications.
Applications: For hot work: Drop forge die and die inserts for forging presses in steel processing, especially with serious wear problems. Hot forming tools (press hardening) of structural automobile parts. Extrusion die for steel processing. Hot pressing die for the processing of copper and copper alloys. Hot shearing blades and flash trimmers. Push bench rollers for the production of seamless steel piping Production tools for seamless steel cylinders (e.g. drawing rollers).
For cold work:Rollers, e.g. Former rolls used for steel rim processing. Punches and shearing blades for sheet thicknesses of approx. 6-12 mm.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 1030-1040°C, interrupt oil or polymer cooling at approx. 250-300°C, or vacuum harden.
Tempering: 500-700°C, as needed, see tempering diagram; temper to increase toughness 2-3 x.
