ASTM AISI H11 Tool Steel Material Mechanical Properti
Tensile strength, ultimate (@20C/68F, varies as soon as heat treatment): 1590 MPa
Tensile strength, go along in addition to than (@20C/68F, varies gone heat treatment): 1380 MPa
Reduction of place (@20C/68F): 50%
Modulus of elasticity (@20C/68F)： 215 GPa
Forged of hot work H11 Steel material metal
Pre-Heating to 750 Then heat to forged temperature. Soak at 1050-1100 C , ensure heat
thorough. After forging, cold slowly.
Heat Treatment of SAE/AISI H11 Steel
- H11 Tool Steel 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
- H11 tool Steel 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 of H11 Steel material
Quenching temperature / ℃ | salt bath furnace: 996
Quenching temperature / ℃ | controlled atmosphere furnace: 1010
The heat preservation time/min: 5 ~ 15
Quenching medium: air cooling .
- Tempering Of H11 Steel
Tempering temperature / : 552
After tempering hardness HRC or future: 52
Application of Sae AISI H11 tool Steel
1, Application in Hot Extrusion Mould
Like Dies, liners, Die holder Backers, Aluminium Extrusion mold, Copper alloy mold, stainless
products mold Etc.
2, Application for Plastic Mould Tool
As Large Injection moulds compression, Thick wall plastic moulds, Etc.
Assured Quality of Sae H11 Steel
Quality assured by Our ISO 9001:2008 feel dealing out system. Our all H11 tool steel all had
