Why are we using molybdenum hafnium carbon(MHC alloy)?
Molybdenum hafnium carbon (MHC alloy) owns high temperature-resistant, has a high level of thermal conductivity, a low coefficient of thermal expansion and a high recrystallization temperature. MHC alloy retains its shape even when used at temperatures of up to 1 550 °C. At temperatures up to 800 °C, MHC is suitable for use in die inserts. A t higher temperatures, we recommend using MHC for full dies. The benefits to you for a long service life:
MHC Alloy Properties:
Outstanding heat resistance
Outstanding creep resistance
Withstands extreme thermal and mechanical loads
Thanks to the uniformly distributed, extremely fine carbides, the material benefits from outstanding heat and creep resistance and, at 1 550 °C, the maximum recommended temperature of use is 150 °C higher than that of TZM.
The advantages of MHC alloy:
Optimum nondeformability and dimensional stability
Low tendency to crack in the case of edged profiles
High thermal stability
High thermal conductivity
Low thermal expansion
No cold brittleness
Good hot ductility
Very high recrystallization temperature
