1: AISI H11 steel 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 A681standard. 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.
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.

6: Heat treatment
Annealing
Slowly heat to 843 – 898(1550-1650 F) then slowly Cool to 538(1000) in heat treatment furnace. Then frosty in make public. After annealing hardness HBS: 235 Max
Hardening
H11 steel having enormously high hardenability and should be hardened by cooling in yet appearance. The use of a salt bath or controlled mood furnace is desirable to minimize decarburization, and if not user-simple, pack hardening in spent arena coke is suggested. The temperature employed is usually 1800-1850F, depending upon size section.
Quenching
Quenching temperature / ℃ | salt bath furnace: 996
Quenching temperature / ℃ | controlled atmosphere furnace: 1010
The heat preservation time/min: 5 ~ 15
Quenching medium: air cooling .
Tempering
Tempering temperature / : 552
After tempering hardness HRC or future: 52
7: Delivery condition
For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
We are professional manufacturer for many years. we can provide a wide range of steel products.
Usually bundling for large diameter,small diameter bars in bulk or as customer's demand.
The hardness after heat treatment is higher than D2/1.2379/Cr12Mo1V1, and can reach 61-63HRC after high-temperature tempering (525 ± 5 ℃); In terms of strength and wear resistance, it exceeds Cr12Mo1V1, and its toughness is higher than D2/1.2379/Cr12Mo1V1; The manufactured molds rarely have cracks and fissures, greatly improving their service life; The residual stress after wire cutting processing is smaller than that of Cr12Mo1V1; The cutting and grinding performance exceeds Cr12Mo1V1.
Suitable for manufacturing precision punching dies and stamping dies for cold forging, deep drawing, and wire rolling for wire cutting processing.
