| 4Cr5MoSiV | 1.2343 | H11 | – |
Mechanical Properties:
Hardness: annealing, ≤235HB; quenching, ≥ 53HRC
Heat Treatment of H11 Steel:
1.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
2.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.
3.Quenching
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
4.Tempering
Tempering temperature / ℃ : 552
After tempering hardness HRC or higher: 52
Application:
1, Application for Hot Extrusion Mold
As Dies, liners, Die holder Backers, Aluminium Extrusion mould, Copper alloy mold, stainless products mold Etc.
2, Application for Plastic Mold Tool
Like Large Injection molds compression, Thick wall plastic molds, Hot work punches Etc.
