High speed steel heat treatment
WebTempering of spring steels (300-500°C): used for spring steels or similar applications. Typically, hardness requirement is around 45 HRC. High temperature (500°C or higher): used for quenched and tempered steels, hot working tool steels and high speed steel. The hardness will vary from 300HB to 65HRC dependent on the material. Process details WebHeat at a rate not exceeding 400°F per period (222°C per hour) to 1150-1250°F (621-677°C) equalize, then heat to 1400-1450°F (760-788°C). For normal tools, use only the second thermal product as a unique preheating treatment. Austenitizing (High Heat): Heat slowly from the warm-up. Furnace oder Salt: 1850-1875°F (1010-1024°C).
