I have some "experience" with tempering and hardening steels using water or oil as the quenching medium in my home shop. Have never tried air hardening steels; what is the method of quenching? Leave it in air to cool after the piece has been heated to hardening temperature, or use an air blast for quicker cooling? What method is used for tempering temperature control (as in water quenching, using the colour as temperature indication)? Would there be any benefit to using air hardening steel over oil hardening steel for wood cutting blades 3/4 inch wide by 3/16 inch thick, used for (commercial) shaving of reed blades (oboe, sax, bagpipe)? All helpful comments appreciated. Ray
