PROPRIETARY Carpenter CTS 20HC Alloy Heat Treatments

  • Annealing: Carpenter CTS 20HC alloy should be annealed in a neutral atmosphere. Heat uniformly to 1550/1650F (843/899C), then cool very slowly in the furnace until the furnace is black. The furnace then can be turned off and allowed to cool naturally. Fully annealed hardness is HRB 100 maximum. Intermediate or process annealing can be performed by heating uniformly to 1350F/1450F (732/788C) followed by furnace cooling or air cooling. Slightly higher hardness will result from the lower-temperature annealing process. Hardening: Preheat to 1400/1500F (760/816C) then increase temperature to 1850/1950F (1010/1066C), soak for 15 to 30 minutes, quench in warm oil or cool in air. Do not overheat. Tempering: Carpenter CTS 20HC alloy can be tempered over a range of temperatures from 300F (149C) to 800F (427C), soaked at least one hour then air cooled to room temperature. The specific tempering treatment chosen will depend upon a number of factors including the austenitizing temperature utilized, application of a refrigeration treatment and the desired combination of final hardness, toughness and corrosion resistance (see hardness table). To remove peak stresses yet retain peak hardness, temper at 300F (149C) to 350F (177C). Tempering at temperatures of 800F (427C) and higher will reduce toughness and corrosion resistance. Sub-Zero Cooling: After hardening, the alloy may be refrigerated at -100/-120F (-73/-84C) for at least one hour then warmed to room temperature prior to tempering to minimize retained austenite. Refrigeration is most effective when performed within two hours after the austenitizing treatment.
