1. H11 Hot Work Steels

1 1. Introduction:

1. Chromium hot work tool steels are designated as group H steels according to the AISI classification system. This series of steels start from H1 to H19. The most commonly used chromium hot work steels are H11, H12, and H13, which can be air hardened in 150 mm thick sections. The steels are subjected to minimal distortion during hardening due to their balanced alloy content. The tools produced from chromium hot work steels can be cooled using water without damage as these steels have low carbon and alloy contents.
This article will give an overview of H11 chromium hot work steels, which have low carbon content and good toughness. These hot work steels can be deep hardened by heat treatment and air-quenching.

6 HEAT TREATMENT:

FORGING: H11 hot work steels are forged at °C (°F). For this type of steels, forging below 899°C (°F) is not preferable.

ANNEALING: H11 hot work steels are annealed at 871°C (°F) and slowly cooled at 4°C (40°F) in the furnace.

HARDENING: Preheat to F and then heat to F and hold for 15 to 40 minutes. Air cool (air quench).

TEMPERING: Tempering is carried out on H11 tool steels at temperature ranging from 538 to 649°C ( to °F) to obtain Rockwell C hardness of 54 to 38. Double tempering can also be performed in these steels every one hour at the preferred tempering temperature.
