1 Introduction K460 die steel is chromium, manganese and vanadium-based Oil quenched alloy steel, hardened and depth of capability, excellent resistance to wear no deformation, can be used for electrical erosion operation. All cutting dies used, such as Die, die notches, printing mold, plastic mold, wire-tapping and screw formwork, wood cutting tool. Detailed parameters Factory state: annealing, the maximum hardness of 225HB Steel Features: This steel is high carbon chromium manganese vanadium alloy steel, high wear resistance and toughness, quenching deformation. Uses: All cutting tools, Die, die notches, printing mold, plastic mold, wire-tapping and screw formwork, wood cutting tool. 2 Chemical composition of elements C Cr Mn WV Si content (%) 0.95 0.50 1.20 0.55 0.12 0.30 3 Heat Treatment Forged: 1050 ℃ to 850 ℃ began forging stop, melted down with furnace cooling. Annealing: 710-750 ℃ ??protective gas furnace slow cooling. Strain Reliefs: 650 ℃ heat 1-2 hours after slow cooling in the furnace. Quenching: 780-820 ℃ heat through heat after quench oil or 200-250 ℃ monitor nitrate solution hardening, tempering immediate cooling to 50-70 ℃. Tempering: tempering temperature and time may refer to the tempering chart. 4 Typical applications? Examples (1) appropriate? Rail scraping?, ?? Cut?, ?? Cut? And saw? (2)? To Die, scissors?
