Alloy steels contain different varieties of steels that exceed the composition limits of Mn, C, Mo, Si, Ni, Va, and B set for carbon steels. They are designated by AISI four-digit numbers. They respond more quickly to mechanical and heat treatments than carbon steels.

Forming:
  • AISI 52100 alloy steel can be formed using all conventional techniques such as cold forging or stamping and hot or cold upset forming techniques.

Heat Treatment:
  • AISI 52100 alloy steel is heated at 816°C (1500°F) followed by quenching in oil.
  • Before performing this process, it is subjected to normalizing heat treatment at 872°C (1600°F) followed by slowly cooling in order to reduce the machining stress.

Forging:
  • AISI 52100 alloy steel is forged at 927 to 1205°C (1700 to 2200°F).

Hot Working:
  • AISI 52100 alloy steel can be hot worked at 205 to 538°C (400 to 1000°F).

Cold Working:
  • AISI 52100 alloy steel can be cold worked using conventional techniques in the annealed or normalized conditions.

Annealing:
  • AISI 52100 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling to reduce cold working or machining stress.

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. This article will give an overview of H13 chromium hot-work steels, which contain strengthening agents such as vanadium and molybdenum.


Other designations that are equivalent to H13 tool steels include:

  • AFNOR Z 40 COV 5
  • DIN 1.2344
  • UNI KU
  • JIS SKD61
  • SS 2242
  • B.S. BH 13
  • ASTM A681
  • FED QQ-T-570
  • SAE J437
  • SAE J438
  • SAE J467
  • UNS T20813
  • AMS 6408Machinability

 

Forming:
  • H13 tool steels are formed by using conventional methods.

Welding:
  • H13 tool steels are readily weldable.

Heat Treatment:
  • H13 tool steels are preheated to 816°C (1500°F).
  • 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.

Annealing:
  • H13 tool steels are annealed at 871°C (1600°F) and slowly cooled at 4°C (40°F) in the furnace.
