    Cr12Mo1V1 is a high carbon, high chromium, and high vanadium tool steel that is commonly used in the manufacturing of cutting tools, molds, and dies. Its high hardness, wear resistance, and toughness make it suitable for applications that require high levels of abrasion resistance and cutting performance.   Cr12Mo1V1 steel is an air hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion resistant properties. It is heat treatable and will offer a hardness in the range 55-62 HRC, and is machinable in the annealed condition.   Cr12Mo1V1 steel shows little distortion on correct hardening.   Cr12Mo1V1 steel’s high chromium content gives it mild corrosion resisting properties in the hardened condition.

    If customer need better machinability, we recommend A2, because A2 has a chromium content of 5% and is more readily machinable.

2:   Cr12Mo1V1 steel application

   Cr12Mo1V1  tool steels are used for long run tooling applications, where wear resistance is important, such as blanking or forming dies, punches, forming rolls, knives, slitters, shear blades, tools, scrap choppers, tyre shredders and so on.

5:   Cr12Mo1V1 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.

7:   Cr12Mo1V1 steel heating treatment

     Cr12Mo1V1 steels alloy should be preheated very slowly to 815℃ (1500°F) and then temperature can be increased to 1010oC (1850°F). They are then held at 1010oC (1850°F) for 20 to 45 minutes and air cooled (air quenched).

Annealing

    Annealing of  Cr12Mo1V1 tool steels material should be done at 871 to 898°C (1600 to 1650°F) followed by slow furnace cooling at 4.4°C (40°F) per hour or less.after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.

Stress Relieving

    When desirable to relieve the strains of machining, heat   Cr12Mo1V1 grade steel slowly to 1050°-1250°F, allow to equalize, and then cool in still air (Strain Relieving).

    Preheat Prior To Hardening

    Preheat slowly to 1350°-1450°F and hold at this temperature until grade steel   Cr12Mo1V1 material is uniformly heated.

Hardening

    After thorough preheating, heat to 1800°-1850°F. Hold the work piece at the hardening temperature until it is completely and uniformly heated.

Quenching

    AISI D2 steel tool material is an air hardening steel and will develop hardness on cooling in still air. To avoid scaling and prevent decarburization of the work piece surface, controlled atmosphere or vacuum furnaces are recommended. If these furnaces are not available, pack hardening, salt baths or wrapping the piece in stainless steel foil will provide some degree of surface protection in the hardening process. Parts should be allowed to cool to 150F, or to where they can be held in the bare hand, and then temper immediately.

Tempering

    The tempering temperature on material   Cr12Mo1V1 steel may be varied according to the desired hardness.  Cr12Mo1V1 steels can be tempered at 204°C (400°F) for achieving Rockwell C hardness of 61 and at 537°C (1000°F) for a Rockwell C hardness of 54.

8: 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.
