Abstract

The critical cooling rate to achieve fully martensitic structures was determined for rimmed and aluminum-killed SAE 1010 steel containing various amounts of carbon and nitrogen. Fine grained aluminum-killed steels required a cooling rate approximately two times higher that rimmed steel for all carbon andnitrogen contents evaluated. Alloying may be required to reduce the critical cooling rate to a rate achievable in oil-quenched carbonitrided components processed from aluminum-killed steel.
