Due to its excellent toughness and resistance to softening under high temperatures, this steel is used in hot work/warm work forging, die casting, and more recently, in hot stamping molds.
AUD61 is a high toughness hot work tool steel with improved toughness, heat strength, and hardenability compared to SKD61.
Optimal for improving life of dies with problems of cracking, chipping and heat checks.
(1) Favorable toughness (2) favorable heat check resistance (3) favorable hardenability
Hot work forging press dies, hot work extrusion dies, casting dies, cutting blades
AUD72 is a high strength hot work tool steel with improved toughness, hot temperature strength and hardenability over SKD7.
Using in place of SKD61, optimal for improving life of dies with problems of heat checks and wear.
(1) Favorable resistance to softening at high temperatures (2) favorable heat strength and resistance to wear
Hot work forging press dies (rapid hot work forging die, hot work closed forging die, hot work extrusion die) casting dies, etc.
AUD91 is a prehardened steel tempered before secondary hardening in advance.
During forging process, the forged material heat is utilized for precipitation hardening of the die surface to improve wear resistance.
(1) Favorable wear resistance (2) favorable hot work strength
Hot work forging press dies (upsetter die, hot work extrusion die)
SKD61 is a type of steel with high toughness preventing cracking or chipping due to the consistent fine annealed microstructure.
(1) Favorable toughness
Hot work forging press dies, hot work extrusion dies, casting dies, etc.
