1045 Steel JIS S45C DIN CK45 EN8 - OTAI Special Steel

1045 steel heat treatment:Annealing of 1045 steel. Slowly heat to 680-750 °C, Cool in the furnace. 1045 steel Hardening. Heat to 820-860°C, quenching in oil or water. 1045 steel Tempering. After quenching, Re-heat to 550-660°C for Tempering, keep about 2 hours. 4140 Tempering Curve - Metal and Metallurgy engineering Sep 11, 2012 · 4140 Tempering Curve 4140 Tempering Curve paras99 (Automotive) (OP) 11 Sep 12 10:18. Hi, does anyone know if there is data available for a hardness vs temperature curve for 4140 steel at a certain time. I have been looking everywhere and cant seem to find it. Your help would be much appreciated. thank you

Machine Steel Hardenability and the Jominy Test

properly quenched 1045 and a 6140 steel bars of increasingly larger diameters. The hardenability curves for five different steel alloys all having 0.40 wt% C, yet differing amounts of other alloying elements, are shown in Figure 5. One specimen is a plain carbon steel (1040); the other four (4140, 4340, 5140, and 8640) are low alloy machine steels. Quenching and tempering of steel - tec-science

To obtain the desired mechanical properties it is necessary to cool steel from the proper temperature at the proper rates and temper them at the proper temperature and time. Isothermal transformation diagrams for SAE 1045 steel are shown in Figure 6-4. Heat Treatment of Steels Tempering Temperature - an overview ScienceDirect TopicsTypically, tempering times are a minimum of approximately 1 h. Thelning has reported a rule of thumb of 12 h in. 1 of section thickness after the load has reached a preset temperature (60) After heating, the steel is cooled to room temperature in still air. The recommended tempering conditions, in addition to recommended heat treating cycles, for a wide range of carbon and alloy


    Isothermal transformation diagrams for SAE 1045 steel are shown in Figure 6-4. Heat Treatment of Steels Common steels, which are really solid solutions of carbon in iron, are body-centered-cubic. However, the carbon has a low solubility in bcc iron and precipitates as iron carbide when steel is cooled from 1600 ºF (870C). The processes of precipitation can be altered by adjusting
