where to get 41xx bar stock

**dnepro-mike** · 06-17-2012, 10:25 AM

i'm conceiving my own receiver but having hard time finding properly sized hunk of steel
i would need a piece of plate or flat bar that is at least 35mm thick and 75 mm wide.
i checked out most usual online metal re-sellers i.e. onlinemetalsupply, speedymetals, onlinemetals
they either don't have what i need or don't have right sizes

i'm willing to travel if I can get source locally. especially if that place can band-saw few pieces to my specs.
any ideas?

Try general supply in New Bedford, MA.

Mcmaster-Carr has a bunch of stuff. Not sure exactly what you need, but here's a link:

They're in Boston. We buy steel and aluminum plates from them

Are you sure you want 4000 series, it's generally very soft in terms of metal? If I were making a receiver from scratch I think I would go with 6000 or even better 7000 series.

ETA; I used to buy my stock from Peirce in Franklin

Hear treated 4140 and 4340 are commonly used in the industry for carbon steel receivers, and can be heat treated to an appropriate hardness for both 1911 frames and slides.

I've never produced my own receiver, but is it worth buying 4000 series just to have to heat treat it after you machine it? What are the benefits? Is it just easier to work with in its raw state?

benefits: machining is easier to do on softer steel. If you were to go with a harder steel, you'd chew through tooling faster.

you start with the 41xx and then heat treat it after you're done forming it.

How fast do you need it?

And how long do you need it to be?

I don't know what kind of receiver you are building, or how complicated it is, but what kind of machining capabilities do you have? If you have access to a full machine shop and can use carbide tools then you can get a piece of pre-hardened 4140. If you are doing it without a milling machine and good tooling than you best get an annealed piece of 4140 that may or may not need to be heat treated when you are done. I say 4140 because it is an all around good quality steel that is readily available and can be heat treated if necessary.

I would first call 3 or 4 local machine shops and ask them for a block of 4140. They probably have a scrap piece in the cast offs that they would sell cheap. If that failed, I would consider the sources below:
