Nital etch testing
Webb28 feb. 2011 · If your mixing it with ethanol for the etching process, don't, anything above 5% can explode unless cooled or just from the heat generated by reacting with the metal... If you have to make your own use methanol, it can't form explosive compounds with metals , and has a much greater long term stability.... WebbNital Etch, also known as Surface Temper Etch and Temper Etch, is a non-destructive test that is used to determine if overheating has occurred in a part (after final heat treat) by abusive machining or grinding that will adversely affect the required properties of the part in question. It is used specifically to look for: Overtempering
