Uses:
Shear blades, Veneer knife, punches, dies, pneumatic tools, chisels, beading tools, caulking tools.
Forging/Rolling:
Heat slowly to 1850° F - 1950° F and hold for uniformity. Do not forge or roll below 1650° F, cool slowly from the forging or rolling temperature. Do not normalize.
Annealing:
Heat slowly to 1400° F, and hold for 1 hour per inch of thickness. Cool slowly to 1000° F; air cool to room temperature. Expect Brinell hardness 229 max.
Hardening:
Heat to 1600° F and hold for uniformity, not to exceed 1/2 hour per inch of thickness. Quench into 150° F oil.
Tempering:
Temper immediately after quenching, before part has cooled to below 150° F. Parts should be held a minimum of 2 hours per inch of greatest thickness. A single temper is sufficient. Tempering temperatures should be between 400° F - 650° F. The above tempering table may be used as a guide. However, since 1/2" dia. specimens were used for this test, it may be found that heavier sections are several points lower.
