Hanyoyin maganin zafi na simintin ƙarfe na carbon yawanci suna daɗaɗawa, daidaitawa ko daidaitawa + tempering. Don wasu manyan simintin ƙarfe na carbon karfe, ana iya amfani da quenching da tempering, wato, quenching + high zafin jiki tempering, don inganta ingantattun kayan aikin injiniya na simintin ƙarfe na carbon karfe. Kananan simintin gyare-gyare na carbon karfe ana iya kashe shi kai tsaye kuma a huce shi daga yanayin simintin.
