Grade Introduction:
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.
 
Grade Application:
H11 alloy steel is often used for highly stressed structural parts such as aircraft landing gear.
Some typical applications: Hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies, and
extrusion tooling.
The tools produced from H11 chromium hot-work steels can be cooled using water without damage as these steels
have low carbon and alloy contents.

Heat treatment:
Tool Steel H11 can be heat treated using various different schemes that give different properties. Heat treatments of this alloy usually consist of annealing, hardening/austenitizing, air and oil quenching, and single or double tempering at temperatures of 840° F (450° C), 930° F (500° C), 1020° F (550° C), 1110° F (600° C), and 1200° F (650° C).
According to some independent studies, the optimum heat treatment for a combination of hardness, toughness, yield strength, ultimate strength, and ductility include oil-quenching and double-tempering at 1020° F (550° C). Higher hardness can be achieved by oil-quenching and double tempering at 1110° F (600° C), but this can also lead to lower lead strength and very low ductility. Also, with the increase of hardness of Tool Steel H11, impact toughness decreases.
 
Hardening:
H11 steel having very high hardenability and should be hardened by cooling in still air. The use of a salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening in spent pitch coke is suggested. The temperature employed is usually 1800°-1850°F, depending on size section.
 
Tempering:
Tempering is carried out on H11 tool steels at temperature ranging from 538 to 649°C (1000 to 1200°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.
