hardening and annealing 0-1 tool steel.
Howdy folks,
Anybody familiar with annealing 0-1 ?. Lately the flat stock I've been getting is harder than normal , so to test my theory about that being caused at least significantly by the condition of the steel as opposed to alloying variances, I annealed a batch of die plates the other day . I was right about that and my guess is that the mill is cutting mfg costs by not fully annealing the stock that the flat-grinders are being supplied with. According to data from Diehl Steel, the slow cooling should take place at 35 deg F max . per hour from 1475 deg to 1110 deg, which takes roughly... a whole freakin day !. Regardless of why the steel is harder than normal, my concern is about degradation that may occur from the steel spending so much time at elevated temps. I wrapped my parts in ss foil and that did keep them clean, and I am assuming that since these are the directions given for annealing, that it's safe to actually do it; that the steel does maintain it's "hardenability integrity " through the process of annealing and subsequent hardening after cold working. Input?. Thanks, DS |
