Increased Carbon, Molybdenum and Nickel over basic die steel compositions offer enhanced abrasion resistance and good impact toughness for the following applications.

Aluminum and Titanium Forging
Appropriate for hammer forging of aluminum where strain rates and the formation of abrasive aluminum-oxide exert strong wear forces on the die.

Warm (Ferrous) Forging
Forging steel at lower temperatures offers improved dimensional precision and improved heating efficiency, but subjects the dies to increased cavity pressures and strong abrasion forces. Water quenched DURODI offers excellent performance under these conditions through a balanced combination of enhanced wear resistance and good impact toughness.

Counterblow Hammers
Large counterblow hammer dies are subjected to incredibly high impact forces and flow stresses. The combination of cold-water quenching and the deep hardening capacity of DURODI provide the microstructure and hardness needed for large counterblow hammer dies.

Machinability
Machinability at all hardness levels is enhanced through patented micro-alloying additions, but where maximum machinability is desired, a fully annealed condition (approximately 248 HB) is available.
