carburize at 910°C in salt or gas
630-670°C
150-200, cooled in furnace
1st pre-heating °C: up to approx. 400 in an air-circulating furnace
2nd and 3rd : 780 and 805°C
780-820°C
EN353 is re-heated to 780C – 820°C, holding until the temperature is uniform throughout the section, and then quenched in oil,Tempering must be done immediately while ithe component EN353 is still hand warm. Heat to 150C – 200°c , soak it for 1 – 2 hours / 25mm of section, and then cooled in still air.
Hardness after Tempering : 62-64 HRC
