AISI H11 / DIN EN X37CrMoV5-1 1.2343 Tool Steel Bar / Rod Dia 20-1000 mm
INTRODUCTION
AISI H11 tool steel is a 5% chromium hot work tool steel that is represented by its excellent impact toughness. Chromium hot-work tool steels are designated as group H steels according to the AISI classification system, and specified in ASTM A681 standard. The most commonly used chromium hot-work steels are H11 tool steel, H12 tool steel, and H13 steel, within the series from H1 to H19.
If we compare between H11 and H13, H11 tool steel consists of less vanadium than the commonly used H13 hot work tool steel. This gives H11 steels the higher toughness, with some reduction in wear resistance and temper resistance. H11 tool steel is a deep-hardening, air-hardening steel and H11 alloy steel could be deep hardened by heat treatment and air-quenching. That gives minimal size change during heat treatment. H11 how work steel also has super resistance to thermal fatigue cracking and superb resistance to gross cracking and thermal shock when water cooled in service.
APPLICATIONS
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.

PROCESSING
Forging of AISI H11 Tool Steel
AISI H11 alloy steels are forged at 1121°C (2050°F). For this type of steels, forging below 899°C (1650°F) is not preferable.
AISI H11 Tool Steel Heat Treatment
Annealing of H-11 steel
Anneal at 871°C and slow cool at 4.4°C per hour or less in the furnace.
Tempering of Steel H11
Temper at 537°C to 648°C for Rockwell C hardness of 54 to 38. Double tempering for one hour each time at the selected tempering temperature is recommended.
