5. ASTM AISI H13 Tool Steel Material Mechanical Properties

Tensile strength, ultimate (@20°C/68°F, varies with heat treatment): 1590 MPa

Tensile strength, yield (@20°C/68°F, varies with heat treatment): 1380 MPa

Reduction of area (@20°C/68°F): 50%

Modulus of elasticity (@20°C/68°F): 215 GPa

6. Forged of hot work H13 Steel material metal

Pre-Heating to 750℃，Then heat to forged temperature. Soak at 1050-1100 °C , ensure heat thorough. After forging, cool slowly .

7. Heat Treatment of SAE/AISI H11 Steel

  • H11 Steel Annealing

Slowly heat to 843℃ – 898℃(1550-1650°F)，then slowly Cool to 538℃(1000℉) in heat treatment furnace. Then cool in air. After annealing hardness HBS: 235 Max

  • H11 tool Steel 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.

  • Quenching of H11 Steel material

ASTM H11 steel Quenching temperature / ℃ | salt bath furnace: 996

AISI H11 steel 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 higher: 52

8. Application of Sae AISI H11 tool Steel
