A11’s composition of high carbon plus high vanadium gives it an exceptional rating for wear resistance, toughness, and strength for cold working tooling applications. It boasts better wear resistance than die steels such as D2 and D7. Machinists choose this metal for its ease of grinding, improved response to heat treatments, and cost-effectiveness. It’s often used in punches, extrusion tooling, slitter knives, and cold work tooling projects.
- Production cutting
Forging: Heat A11 slowly to 2000°-2100°F. Cool slowly and anneal immediately after cooling
Annealing: A11 must be annealed after hot working and before rehardening. Heat slowly to 1600°-1650°F at a rate of not more than 400°F per hour. Hold at this temperature for 1 hour per inch of maximum thickness or 2 hours minimum. Cool to 1000°F at a rate of no more than 30°F per hour. Air or furnace cool to ambient temperature.
Quenching: For A11 sections less than 3” thick, air cool to maximum hardness. Cool sections thicker than 3” at a faster rate. For pressurized gas, the furnace should have a minimum quench pressure of 4 bars. The quench rate to below 1000°F is critical to obtain the desired properties. For oil, quench until black, about 900°F then air cool to 150°-125°F. For salt, maintain the temperature at 1000°-1100°F, equalize in the salt, then air cool to 150°-125°F.
Tempering: Temper immediately after quenching. Temper A11 tool steels between 1000°-1100°F. Do not temper below 1000°F. Hold at this temperature for 2 hours then air cool. A11 requires double tempering. Triple temper when austenitized at 2100°F.
