Brief 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.
H11 alloy steel is often used for highly stressed structural parts such as aircraft landing gear.
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.
Application:
-Hot punches,
-forging dies,
-hot shear blades,
-hot gripper dies,
-extrusion tooling.
