Designed to retain hardness at elevated temperatures, and to withstand the effects of alternate heating and cooling, H13 is used extensively in aluminum extrusion, aluminum die casting, and forging die applications. Its exceptional toughness and inherent resiliency have also made this a popular material for die-castings in the cold heading field. H13 is recommended in a wide range of hot work applications.

Preheat slowly to 1300° F - 1500° F and soak thoroughly. Then raise to 2050° F – 2150° F. Do not forge or roll below 1650° F. Cool slowly from the forging or rolling temperature. Do not normalize.
Heat slowly to 1600° F, and hold for uniformity, cool at a rate of 30° F per hour to 900° F, then air cool. Expected Brinell hardness 207 max.
Preheat to 1300° F - 1400° F, soak until uniformly heated, and either transfer or raise furnace temperature to 1850° F, and hold one hour per inch of greatest thickness. Quench in still air and temper without delay.
Temper immediately after quenching, before the part has cooled to below 150° F. Parts should be held a minimum of 2 hours per inch of thickness. Double tempering is recommended for the H-13 grade. For hot work applications, H-13 should be tempered in the 1100° F – 1150 ° F range. The following tempering table may be used as a guide. However, since ½” diametric specimens were used for this test, it may be found that heavier sections are several points lower.
