Not too many ovens go to 600 deg. Old timers method of annealing springs that are first hardened/quenched is to dunk in motor oil, and just burn off the oil. But a bullet casting thermometer can read to 600 deg, so you can use an electric hotplate, with a 50/50 solder bath to dunk the spring in to bring it to 600, let cool slowly(out of the solder!).

Thats true most newer ovens dont go to 600 .I turn it all the way up and watch the color. I like to work with a chunk of 1980's ford truck leaf spring But I forge my springs into profile on a coal forge using rice coal Turns white-red in 6 seconds melts in 12 so no snoozing

i made some simple springs out of the brownells 1095 for a test heated red hot quenched in oil, tempered in lead bath i varied the time in the lead bath the 1095 required more time than the car spring material i was using.1075 i think.you can heat and draw the temper with a propane torch by reading the color.if you file on the spring to see if it soft enough when you are finished.mc
