It has excellent high temperature strength, good toughness and thermal shock resistance. CHARACTERISTICS OF KMX1 Harder than that of SKD61, SKD62 and SKD7. Excellent high temperature strength 1 Excellent in toughness and thermal shock resistance compared to SKH51 and SKD7 Exceptional toughness and thermal shock resistance 2 Stable n tr dec layer with high softening resistance is obtained excellent in thermal fatigue life. Stable nitriding characteristics 3 KMX1 is suitable for the hot forming mold which needs intensity and toughness at high temperature. APPLICATION OF KMX1 Die, Punch, Insert, Hot extrusion stem, Shear Blades, Tool steel for hot warm forging that needs toughness, Tool steel for hot work that needs heat resistance Example POSITION OF KMX1 HIGH TEMPERATURE STRENGTH 2 times or more of tensile strength than SKDC62 and 1.4 times or more than SKD7 in a temperature O region of 650 C or more. SOFTENING RESISTANCE Higher hardness than that of SKD62 and SKD7 O even after being held at 650 C for 100 hours.
