Annealed hardness range is normally 235 to 245 Brinell. The hardening temperature range for A6 is from 1500'-1600°F. Tools with simple shapes may be heated directly to the hardening temperature from room temperature.
What are the 6 types of tool steels?
Tool Steel is divided into these six groups: water-hardening, cold-work, shock-resisting, high-speed, hot-work, and special purpose. The determination of a choice from the group will depend on; the cost effectiveness, working temperature, required surface hardness, strength, shock resistance, and toughness requirement.Mar 23, 2015
