Heating For Oil Quench #blade #knife #blacksmith #diy #knifemaking #metalworking #forged #vikings -

: Using a magnet is a standard DIY tool; once the steel stops being attracted to the magnet, it is at roughly 1,414°F. You should then heat it slightly further to reach the required quenching temperature for your specific steel.

For oil quenching a knife blade, the steel must typically be heated to its , which generally falls between 1,400°F and 1,650°F depending on the specific alloy. A common practical method is to heat the blade until it becomes non-magnetic and then continue heating it for a brief period—often just a few shades brighter in color—to ensure it has fully transitioned to the austenite phase before rapidly plunging it into the oil. Heating the Steel (Austenitizing) : Using a magnet is a standard DIY

The oil itself must be preheated to work effectively. Cold oil is more viscous and may cool the metal too slowly or unevenly. Heat Treating Knives : 7 Steps - Instructables A common practical method is to heat the
