Heat treat 410?

[John_Dennis]

I bought some stainless at the scrap yard that they claimed was 410. It cuts like cold rolled steel as long as it does not get hot.

I am trying to harden it a little but heating to orange and quenching in oil anneals instead of hardening.

Am I doing this wrong or is this material likely to be some other stainless alloy?


Thanks

This might give some direction.

Hardening Stainless Steels: A Brief Guide

In this blog post, Masteel will briefly outline some of the challenges and solutions associated with hardening stainless steels.

Is it magnetic? 400 series stainless steels are.

You need to heat to 1800 F. That is above orange heat.

Not magnetic. They were using an XRF gun to test the metal. Not sure if they know much about alloys, probably just looking for nickel content.

This does seem to be a free machining alloy but not magnetic at all

Last time I took stuff for scrap, their XRF said 310 SS was 316, 310 is magnetic.

I Googled it, found the following, it says that it is hardenable, but they do not state the hardness that can be achieved.

"Free machining" sounds more like 303 SS. If it were a 400 series, it would be magnetic.

This project was a oval hole punch for leather belt making. If I was going to purchase material specifically for this, what would be a good choice? Would A1 or A2 work well or would O1 or 02 be better?
