Mechanical properties are not stated in AISI 8620 or SAE 8620 as standard. The mechanical properties information for AISI 8620 / SAE 8620 is provided below as a guida. A test piece of 19mm diameter AISI 8620 / SAE 8620 is blank carburised for at least one hour at a temperature of between 880-930°C and allowed to cool at room temperature. The test piece of AISI 8620 / SAE 8620 is then re hreated to 820-840°C and quenched in oil.
