Hi Steve. The process for the forging of the new bought stock 5160 was as follows. Forged and then allowed to cool. The Normalizing was done above non magnetic. Normalised again at just on non magnetic and then again at just below non magnetic. All of the above in a Temp congrolled Kiln. The quenching was done once the blade was heated to 843°C and then quenched in oil. The shadows had all gone and the transformation phase had occured before the quench. The time from Kiln to oil was less than 1.5 seconds. I don't know what oil it was but I do know it was a fast quench oil as I did ask. The blade was then annealed after hardening at 600, 400 and 250°C in the Kiln. I have been making knives now for about 2 months and therefore don' know all the terminology and I did get the normalising and annealing mixed up. My error. The blade was file tested and it was extremely soft. I had enough steel to remove a piece with a grinder and then snap it which allowed me to look at the grain through a HP Loop. The grain was visibly minute but yet still soft. Is there any further information you need.
