Cold-work tool steels which include D2, D3, D4, D5, and D7 steels are high-carbon, high-chromium steels. Apart from D3 steel all group D steels have 1% Mo and are air hardened. Type D3 steel is oil-quenched; though small sections can be gas quenched after austenitization using vacuum. As a result, tools made with type D3 steel tend to be brittle during hardening. Type D2 steel is the most commonly used steel among the group D steels. The D3 steels contain 1.5 to 2.35% of carbon and 12% of chromium. The D3 tool steel should be cooled to room temperature and should be tempered immediately.


Equivalent metals of D3 steel are:

  • • AFNOR Z 200 C 12
  • • DIN 1.2080
  • • UNI X 21O Cr 13 KU
  • • JIS SKD1
  • • B.S. BD 3
  • • ASTM A681
  • • FED QQ-T-570
  • • SAE J437
  • • SAE J438
  • • UNS T30403Annealing


Product Details:

  • Annealing of D3 tool steel needs to be done in a controlled atmosphere furnace.
  • D3 tool steels should be heated thoroughly to 871°C (1600°F) and cooled slowly at a rate of not more than -6°C (20°F) per hour, until the furnace is black.
  • Then the material should be removed and air cooled.

Heat Treatment:
  • D3 tool steel requires hardening and tempering to achieve maximum properties.
  • For maximum accuracy, the parts of D3 tool steel should be stress relieved after roughing operations.
  • Stress should be relieved at 648°C (1200°F) for one hour and cooled slowly.

Stress-relieving:
  • After rough machining the tool should be heated through to 650°C (1200°F), holding time 2 hours.
  • Cool slowly to 500°C (930°F), then freely in air.

Hardening:
  • D3 tool steel should be heated properly since it is very sensitive to overheating and if not heated maximum hardness cannot be achieved.
  • The work should be directly placed in a furnace preheated to 954°C (1750°F) and soaked for 20-25 minutes, plus 5 minutes per inch of thickness, and then oil-quenched to harden it.

Oil Hardening Non Shrinking Die SteelBlanking and stamping dies, Punches, Rotary shear blades, Thread cutting tools, Milling cutters, Reamers, Measuring tools, Gauging tools, Wood working tools, Broaches, Chasers. An ideal type oil-hardened steel which is economical and dependable for gauging, cutting and blanking tools as well as can be relied for hardness and good cutting performance. O1 Tool Steel is an electric-furnace melted, oil-hardened, non-shrinking, general-purpose tool steel. It is chemically composed of approximately 0.95 percent carbon, 1.1 percent manganese, 0.6 percent chromium, 0.6 percent tungsten and 0.1 percent vanadium. The hardening temperature of O1 tool steel is between 790 degrees Celsius and 820 degrees Celsius.UsesO1 Tool Steel is not easily abraded, has high surface hardness post tempering, does not deform during hardening and can be machined well. Further, it also has a low hardening temperature (and, therefore, can be heat treated in homes and shops), and does not lose shape during quenching. It is inexpensive and readily available. O1 Tool Steel is ideal for making tools and knives, as it can be easily sharpened. Strength and HardnessStrength of a metal determines the extent to which it may deform when load is applied on it. Strength can be measured based on various parameters, such as the maximum ability to take strain, resistance to wear and tear, impact handling, or how the material performs when subjected to frequently changing load conditions. Strength generally increases as the carbon and manganese content increases. Given the high percentage of both of those, O1 Tool Steel is strong. Hardness of a material indicates its resistance to get indented that is not temporary (i.e.; it persists even after the load conditions are removed, as opposed to the strength that is an indication of its performance only when the load is applied), and carbon is also the primary hardening element in steel. The Rockwell method measures the hardness of O1 Tool Steel to be in the range of 64 RC to 58 RC (this is the most commonly used measurement technique).ApplicationAll press cutting tools & punching tools for thinner materials. Small tools of complicated design for reforming, bending & drawing. Small plastic & rubber moulds.

Toughness and Brittleness:
  • Toughness of a material determines whether it can be subjected to shock conditions, and the extent to which it may undergo deformity in shape but still not snap.
  • If subjected to a proper treatment process, O1 Tool Steel tends to be very tough.
  • As opposed to toughness, brittleness measures whether a material will snap instead of getting deformed, when load is applied.
  • Alloy steels like O1 Tool Steel are less brittle than cast or pig iron because of the presence of magnesium.

Chromium hot-work tool steels are designated as group H steels according to the AISI classification system. This series of steels start from H1 to H19. The most commonly used chromium hot-work steels are H11, H12, and H13, which can be air hardened in 150 mm thick sections. The steels are subjected to minimal distortion during hardening due to their balanced alloy content. The tools produced from chromium hot-work steels can be cooled using water without damage as these steels have low carbon and alloy contents.

  • Then the steels are directly heated by increasing the temperature to 1010°C (1850°F) followed by holding for 15 to 40 mins. The steels are then air-quenched.

Forging:
  • H13 tool steels are forged at 1079°C (1975°F).
  • For this type of steels, forging below 898°C (1650°F) is not preferable.

Cold Working:
  • Cold working may be carried out on H13 tool steels using conventional methods.

Soft Annealing:
  • Protect the steel and heat through to 890°C (1630°F).
  • Then cool in the furnace at 20°C (40°F) per hour to 850°C (1560°f), then at 10°C (20°F) per hour to 700°C (1290°F), then freely in air.

Stress-relieving:
  • After rough machining the tool should be heated through to 650°C (1200°F), holding time 2 hours.
  • Cool slowly to 500°C (930°F), then freely in air.

Hardening:
  • Preheating temperature: 600-850°C (1110-1560°F)
  • Austenitizing temperature: 1020-1050°C (1870-920°F), but usually 1020°C-1030°C (1870-1885°F).

Tensile strength at room temperature:
  • The tensile strength values are to be considered as approximate only.
  • All samples were taken from a bar (in the rolling direction) 25 mm (1″) diameter.
  • Hardened in oil from 1025 ±10°C (1880 ±20°F) and tempered twice to the hardness indicated.

Welding:
  • Good results when welding tool steel can be achieved if proper precautions are taken to elevated working temperature, joint preparation, choice of consumables and welding procedure.
  • For best result after polishing and photo-etching use consumables with the same composition as in the mould.

Tempering:
  • Choose the tempering temperature according to the hardness required by reference to the tempering graph.
  • Temper minimum twice with intermediate cooling to room temperature.
  • Lowest tempering temperature 250 °C(480 °F). Holding time at temperature minimum 2 hours

GradeDB2
ApplicationIndustrial

DB-2There are three prime requirements for a Die Block
1. That is readily machineable.2. That it will resist stresses imposed in service without fracture.3. That it will produce the required number of forgings without losing shape and at the lowest cost. Most dies used by the drop forging industry are supplied in the pre-hardened condition and must be readily machineable at high hardness levels. Very low sulphur contents make machining extremely difficult. Those steels normally supplied hardened are therefore manufactured with controlled sulphur content of .010 to .030%. Die blocks are subjected to triaxial stresses and uniformity of mechanical properties is a desirable condition. Press forging demands a die steel with good wear resistance that can withstand the massive compressive stresses and produce forgings to close tolerances. Hammer forging on the other hand requires a predominantly tough die steel, with wear resistance usually the secondary consideration.
