MHC is a particle-strengthened Mo-based alloy with an excellent high-temperature strength. The addition of Hf and C leads to the formation of fine-distributed Hf-carbides, which are very stable leading to high particle hardening - even in the high-temperature area (up to 1550°C). The average nominal chemical composition in weight%: 1.2 Hf, 0.1 C, remainder Mo.

Advantages compared to pure Mo:

• higher high-temperature strength
• higher recrystallization temperature
• better creep resistance

Advantages compared to TZM:

• higher high-temperature strength and therefore higher application temperatures of 100-150 °C

Typical areas of application:

• extrusion dies
• billets for the isothermal forging
