Most susceptible to the phenomenon of strain-age embrittlement are low-carbon rimmed or capped steels that are severely cold worked during forming processes.Subsequent moderate heating during manufacture (as in galvanizing,enameling,or paint baking) or aging at ambient temperature during service may cause embrittlement.
