ferritic stainless steel by quenching from the intercritical annealing temperature to below the
martensite start temperature of the intercritical austenite prior to the partitioning of interstitials
C and N to the austenite at or above the quenching temperature. Partitioning temperatures
as high as 500° C were associated with austenite enrichment, indicating the suitability of
quenching and partitioning processing for stainless steels.
