After the Southern Alberta Hammer In, I did some tests on my W2 stock (Aldo's new batch) and found the sweet spot in my shop at 1460f austentize after normalization and grain refinement. As I was experimenting in 10f intervals, at 1470, there was a lot of inconsistency in the readings with a low of Rc66, and a high of Rc70.5. At 1480f, the overall Rc dropped to Rc64.
Averages were:
1440f, Rc63
1450f, Rc66
1460f, Rc68 (Consistent 67-69)
1470f, Rc68 (a lot of variance 66-70.5)
1480f, Rc64
Is there an explanation for the 1470f high reading other than equipment error? I am using a handheld tester, which is pretty accurate, but at the edge of its range it can be a bit less accurate. I have never had a reading that high before.
