[QUOTE="Trickymissfit, post: 957701, member: 25383"] your on the right track, and to go deep I need a good heat treat manual or else hunt up some steel manufacture's data books as they often come with that data. I add a lot of steel normalized thru my years. and 1050f seems a tad light even for good quality hot rolled plate maybe 1200f to start with. I do remember one normalizing furnace that ran close to 1400f, but it was special (owned by TACOM). Was a high speed unit for quick work. A typical prehardened blank at 1050F will start to draw back quickly as the soak gets deeper and time lengthens in duration. I wouldn't, but it's not my piece of steel as well. I would use nothing but plasma or gas injection in the longest process allowed. The 900F is what they had these furnaces setup at, and never questioned the thoughts of the metallurgical engineer that setup those processes. gary [/QUOTE]
