Quick Details
1: D7 steel introduction
D7 tool steel is a high carbon, high chromium air hardened tool steel with excellent wear resistance. The high carbon and vanadium content results in the presence of a large number of hard vanadium carbide particles in the steel, which have a hardness of about 80 to 85 Rockwell C. Resists wear in sliding contact with other steels and in contact with dry and wet slurries of hard abrasive particles.

4: D7 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

6: Heat Treatment
Heat treatment temperatures, rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, the quenching medium and work piece transfer facilities. Please consult a heat treatment specialist for full guidance on heat treatment.
7: Delivery condition
For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
