I see lots of discussion on heat treating but just short notes on the draw. I have done searches on the net for 15n20 draw specs for spring temper and cannot find charts for 1084, L6. I am doing some blades for a machine made for a very specific purpose, removing floor tile. I invented a machine 10 yrs. ago to do this and we used just blue spring but have made a few for a client and we are now trying to better the blade. Anyone know where I can find some good charts. Thanks.
