Temper time

percy

When I draw my blades after heat treat to temper them, I was wondering if I left them in the oven over the specified time on the draw would it have an ill effect on them.
I heat treat 154-cpm at 1950 and then draw at 900 for two hours two times. What I am asking is if on the second draw if I left them in the oven for say three hours would that effect them.
Kindly a round about way to ask.
After over 20 years of doing this I should already have the answer, but not so.
Thanks for all the response I will get.
You Knifedogs are great with answers.

I don't see why it would, even at those temperatures. It's not hot enough to austinize the steel and grow grain and it's not long enough to cause grafitization. Some people who regularly handle stainless might have other ideas but nothing that I've read would indicate that this should be a problem.
