    It sparks a yellow color but they are short which suggests a high speed type steel. I tempered them at 375F for two hours. The other three segments of saw blade were nice and straight after quenching. The blade section warped a little which is typical for blade sections taken down to a finished dimension. Grinding induces some stresses that even out in the heat and quench cycle.
