PROPRIETARY CarTech S2 Tool Steel 熱処理
- Decarburization: Steel, like all high-carbon tool steels, is subject to decarburization during thermal processing and precautions must be taken to control this condition. Modern furnaces are available which provide environments designed to minimize decarburization.
Normalizing: Forgings are normalized by heating to 899°C (1650°F) and cooling in air.
Annealing: For annealing, steel should either be placed in a controlled atmosphere furnace or packed in a suitable container, using a neutral packing compound. Heat uniformly to 746-774°C (1375-1425°F) and cool very slowly in the furnace at a rate of no more than 11°C (20°F) per hour until the furnace is black. The furnace may then be turned off and allowed to cool naturally.
Hardening: During hardening, suitable protection should be provided to prevent excessive scaling and decarburization. First, heat the salt bath or furnace to 843°C (1550°F). Without preheating, place the tool right in the hot furnace near the thermocouple and let it heat naturally until it uniformly matches the color of the thermocouple. Soak five minutes per inch of thickness, then quench in brine. All water hardening steels should be quenched in 5% to 10% brine and may be quenched right down to bath temperatures. Use flushing fixtures for quenching tools having hollow impressions. Small tools under about 12.7 mm in diameter can be heated to 871°C (1600°F) in controlled atmosphere furnaces or neutral salt baths and quenched in oil. This procedure results in less distortion and size change and less danger of cracking. Control of decarburization can be accomplished by using any one of the several modern heat treating furnaces designed for this purpose. If endothermic atmospheres are used, a dew point between +7-10°C (+45-50°F) is suggested. In older type manually operated exothermic atmosphere furnaces, an oxidizing atmosphere is required. Excess oxygen of about 2 to 4% is preferred. If no atmosphere is available, the tool should be pack hardened or wrapped in stainless steel foil to protect its surface.
Stress Relieving: To relieve machining stresses for greater accuracy in hardening - first, rough machine, then anneal below the critical from 649-677°C (1200-1250°F) and cool slowly - then finish machine.
Tempering: Most tools should be tempered at 149°C (300°F). Shanks of pneumatic chisels should be tempered at 482°C (900°F). When Solar tool steel is oil quenched from 871°C (1600°F), temper at 135-149°C (275-300°F) to relieve hardening strains. Do not temper solar tool steel to color because a straw color begins to appear at 204°C (400°F) - which is too high a temperature for most tools. Solar tool steel may be tempered back and used at lower hardness if evaluation of the application indicates that the sacrifice in wear resistance and gain in ductility warrant the higher tempering temperature.
Forging: Forge from a temperature not over 1149°C (2100°F). Heat rapidly and avoid unnecessary soaking in order to minimize surface decarburization. Cool the forgings in dry air.
