    A2 Steel Application

    The application is decided by A2 steel chemical composition and properties.

    It has high hardness and toughness.

    The application as below: 1 - Precision stamping die.

    2 - Precision blanking dies for wire cutting and stamping die for various purposes.

    3 - Cold forging, deep drawing and boring molds.

    4 - High-speed punching punch, stainless steel plate punch.

    5 - shear and slitter blades.

    A2 Steel Round Bar Sheet Plate Heat Treatment

    Stress Relieving

    After heavy grinding or machine, it is advisable to stress relieve tool steel 1.2363 to reduce the danger of cracking or distortion during subsequent heat treatments.

    Heat slowly to 670-700°C, soak for a minimum of two hours per 25mm of the section then cool down in the furnace.

    Annealing

    1.2363 tool steels are annealed at 857°C (1575°F) and then cooled slowly in the furnace at a rate of 4°C (40°F) per hour or less.

    Hardening

    Preheating temperature: 1200–1380°F (650–750°C).

    Austenitizing temperature: 1700 –1780°F (925–970°C) but usually 1720–1760°F (940–960°C).

    Tempering

    1.2363 tool steels are heat treated at temperatures ranging from 177°C (350°F) for Rockwell C 62 to 538°C (1000°F) for Rockwell C 56 and then tempered.

    Quenching

    Martempering bath or fluidized bed at 360–430°F (180–220°C) or 840–1020°F (450–550°C) then cool in the air.

    Circulating air or atmosphere.

    Vacuum furnace with an overpressure of gas at cooling.

    Oil (only for small and uncomplicated tools).

    Nitriding

    Nitriding will give a hard diffused surface layer which is very resistant to wear and erosion, and also increases corrosion resistance.

    Nitriding Din 1.2363 steels in ammonia gas at a temperature of 975°F (525°C) gives an A2 steel surface hardness of approx.

    Welding

    DIN 1.2363 tool steels are alloy steels and hence they are capable of being welded.

    However, welding of 1.2363 tool steels is not much preferred due to the risk of crack formation.

    The following guidelines can be followed during the welding of 1.2363 steels: A.

    Welding in order to harden the soft annealed 1.2363 tool steel 1 - Heat to austenitizing temperature

    2 - Cool to approx.

    500°C (932°F)

    3 - Weld at approx.

    500°C (932°F)

    4 - Cool to approx.

    100°C (212°F)

    5 - Hard facing electrode B.

    Repair welding of 1.2363 tool steels in hardened and tempered condition 1 - Preheat to the tempering temperature (min.

    200°C) (392°F)

    2 - Weld at the tempering temperature

    3 - Heat immediately to tempering temperature, but max.

    300°C (572°F).

    Soak the steels for 3 hours

    4 - Cool in the air to approx.

    80°C (176°F)

    5 - Heat to tempering temperature.

    Soak for 2 hours

    6 - Hard facing electrode C.

    Welding of soft annealed A2 tool steel 1 - Preheat to 300-500°C (572-932°F)

    2 - Weld at 300-500°C (572-932°F)

    3 - Stress relieve immediately.

    4 - Cr-Mo alloy electrode for welding structural steel Heat Treatment

    A2 tool steels are heated slowly to 788°C (1450°F) and this is followed by increasing the temperature to 954°C (1750°F).

    1.2363 tool steels are further held at 954°C (1750°F) for 30 to 45 minutes and finally removed from the furnace and cooled.

    Machinability

    1.2363 tool steels have medium machinability, about 85% that of the W group of tool steels which are rated at 100% for a baseline.
