A Simplified Guide to Heat Treating Tool Steels

Obviously, vacuum heat treating furnaces do not allow quenching outside of the furnace unless the vacuum furnace has been equipped with an attendant oil quenching zone. Small and medium sections of air hardening steel will devel-op full hardness when quenched by the inert gas backfill. However, larger sections will not develop full hardness unless

A Simplified Guide to Heat Treating Tool Steels

Unlike hardening which requires a quench after soaking at the hardening temperature, the essence of annealing is very slow cooling from the annealing temperature. By way of example, A2 tool steel is annealed by heating to 1550 degrees A2 Tool Steel (UNS T30102) - Air-Hardening, Medium-Alloy 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). A2 tool steels are further held at 954°C (1750°F) for 30 to 45 minutes and finally removed from the furnace and cooled.
