low quantity heat treating?

[Chilidaugz]

I got some parts (replicated from broken gun parts) that need to be heat treated, but nobody I have found in the Inland empire will quote for such low quantity (and is ISO certified).

Any ideas?

Try Pacific metallurgy. they are not local but they will do small part runs for a flat fee.

Now it also depends on what the part were made from. if the proper material wasn't used to begin with no amount of heat treat will help.

May I ask what parts you had made and from what material grade did you use??

Some S7, some durabar, 17-4 precipitated, and 4140.

Some choke tubes, some screws, and a charging handle

Thanks for the lead fellows I will see who quotes best.

What about having then cryo'ed?

That's going to suck as the will probably be different lot charges for each type of material.
Also, you probably want them tempered to different hardnesses too...

I have a programmable kiln and it would still be a bunch of work doing each type of material as its own batch.

cryo don't heat treat, it is a stress relief

17-4 is going to be the difficult one as it is a time consuming operation to age harden.

The other stuff is basic but will require separate runs to do it.

A lot of heat treaters will do one or two items you just got to pay for it. If you aren't willing to spend a couple hundred no one is going to do it.

17-4 SS is precipitation hardened and is usually cheaper than through hardened low carbon steels. It also is treated at a much lower temperature minimizing any movement of the material. It also leaves that awesome color on the part.
