I have a heat treating question. I am new to this steel cpm s90v) and heat treating in general. I ground a couple of fairly thin 9" fillet blanks. I am thinking that something went wrong during my normalizing cycle. Perhaps brining it up to temp, holding, and then letting it cool in the furnace may allow it to cool too quickly. (instructions says ramp down 25 degrees per hour to 1000) At any rate, I got a bad bend upon quench. (Oil) I figured I could fix it during a tempering cycle but ended up snapping it. Any suggestions would be appreciated.
Thanks
Jim
