SLD characteristics of cold die steel, high wear resistance, good hardenability, heat deformation small, easy to process.
SLD uses
Heavy-duty cold or hot stamping die mold repair, should produce a sharp knife, scissors, shape complexity of the cold stamping tools.
SLD heat treatment parameters
Forging :1050-950 ℃
Annealing: Heat to 800-850 ℃, remain at this temperature in 1-3 hours, the furnace is allowed to gradually cool.
Hardening: Heat slowly to 500-750 ℃, and then heated to 1000-1050 ℃ in oil or cool in still air, cooling and decided according to the effective thickness of the workpiece, generally below 10mm air-cooled to room temperature.
Tempering: heating to 150-200 ℃ or 500-550 ℃, to stay at this temperature and then cooled in still air, tempering temperature of 150-200 ℃; and focus on the toughness required after discharge wire cutting or WED EDM machining, the tempering temperature should be 500-530 ℃.
Hardness: 55HRC or more.
Uses:
This steel easy turning, and the system should be sharp knife, scissors, saw, metal stamping dies, forming rolls, a
Like cold or hot for cold mold repair mold, side drum, screw pattern, line mode, cutter, red Lang mold, round roll
Tube, the system power transformers heart dies, cutting the skin rolled steel knives, steel forming roller, special roller forming, fine
Density regulations, complex shapes of cold tools, metallurgy, tin for mold, plastic mold, the screw starts with molds.
