Abstract:

Austenite transformation characteristics were determined for ASTM a723 steels prepared by various suppliers and refining methods. Standard measurement techniques as well as differential thermal analysis and thermomagnetic analysis were employed. Remarkably large variations in hardenability are found among these steels the variations appear to be due to differences of less than one percent in the nickel content among the samples. These hardenability properties are shown to correlate in a straightforward way with mechanical properties of large size components that were quenched at different rates.
