Need More Help on 440C Heat Treating ??

[heatride]

Mike thanks for the link but it said 440C hold for 5 minutes. I am sure that has to be a mistake. Also I forgot to say in my last post I make a lot of folders and I need some information on how to Heat Treat the springs & rockers. Any info you folks give I really am thankfull. Have a nice day.

This one says half an hour, but I don't think that is right. It usually means half hour per inch of thickness(at least on 440C).
But I could be wrong. Maybe someone else can chime in here(subliminal message;Paul Bos ).
