Outline
K460 as chromium, manganese and vanadium-based alloys of the oil quenched steel, have the ability and depth of hardening of good anti-wear deformation, can be used for electrical erosion operation. For all cutting mold, such as Die, notches mode, printing mold, plastic mold, wire tapping and screw formwork, wood cutting tools and so on.
Feature
K460 is Bailu micro deformation cold-working die steel, chromium, manganese and vanadium-based alloys of the oil quenched steel. Micro-deformation heat treatment, high hardness, toughness, resistance to cracking; have the ability and depth of hardening good, wear no deformation, can be used for electrical erosion operation. Easy processing, good sharp edge to maintain, heat treatment is easy. Requires smaller die life of the steel is recommended. Factory state: annealing, the maximum hardness of 225HB



Steel properties: this is chrome-manganese steel, vanadium alloy steel of high carbon, high wear resistance and toughness, deformation hardening [1] small.
Use
All cutting tools, Die, die notches, printing mold, cover mold, plastic mold, wire tapping and screw formwork, wood cutting tools and so on. Forging: 1050 ℃ to 850 ℃ began forging stop, melted down with the furnace cooling. :710-750 ℃ ​​annealing furnace slowly to protect the cold gas. Stress Relief: 650 ℃ heat for 1-2 hours followed by slow furnace cooling. Quenching :780-820 ℃ after quenching oil and heat through insulation or 200-250 ℃ nitrate monitoring solution hardening, tempering the cold to 50-70 ℃ immediately. Tempering: tempering temperature and tempering time can refer to the chart.
