Steel Mills?
Existential Angst
Who? Where?
Tryna find a few for a hard-to-find product, sheets of 304 SS half-hard (no
substitutions), on the order of .075, for a punch press job.
My buddy thinks he has to find a mill for this, but maybe a really good
sheet or roll supplier would have this in stock.
The poundage is considerable, about 40,000 lbs.
I found a couple of bonafide mills on Thomasnet.com, but there has to be
more than this. Unfortunately, Thomas does not do the best job of filtering
out types of companies, at least not for me.
I figgered steel mills, being the lynchpin of Merkin industry, wouldn't be
so elusive.
But a stock supplier would be even better.
Any links, clues, directories?

Thanks, will check them out. We are in/around the oh-ficial Center of the
Universe: NYC.
Did a little more digging/talking, and Thomasnet.com has a substantial
listing of "Stainless steel sheet" suppliers, and someone there has to know
whazzup.
Here's the problem:
301 halfhard is readily available. So far no good on 304 HH, with some
telling me they've never heard of it, and others saying they *might* have
heard of it. But, it's on the spec.
Makes me wonder if what is currently being delivered is 304!!
What would the diff be between the two, anyway? Anything really
consequential?

Oh, I don't expect to find anything esp. close to NYC -- at this point, ANY
supplier would do.
I suspect there's a place on/near the east coast, and NJ/PA would be great,
but I'm not holding my breath.
This is going to be a punched product.
Instead of starting with 304 HH, how bout punching regular 304 and
then tempering the punched pieces at a local heat treater? My buddy sez the
two are not equivalent and inspectors would be able to tell the difference.
He thinks the half-hard has more to do with the rolling process than
subsequent heat treating.

I hope you get an answer from someone who's really familiar with stamping
stock, but you know that I covered materials for _American Machinist_ for
years and I never heard of half-hard stainless. Half-hard aluminum, yes.
Half-hard brass, too. But not stainless.
However, it may be a common term in stamping. Those people live in a world
apart from machinists, for the most part. I can imagine what it is (probably
given a heat treatment after rolling to partially anneal it -- something
like normalizing), but, once again, I never heard the term applied to
stainless of any kind.
If you found it in 301, why don't you track down the mill that's making it
and ask them? If they use the term for 301, and if you can find the original
source for it, they ought to be able to tell you what the story is with 304.

301 is easier to work harden than 304, which is why is it's the most
commonly used material for SS springs, and presumably why it's easier
to find in the work hardened condition than 304. I think it's somewhat
less corrosion resistant than 304.

He's right. I'd check with Ryerson, Yarde, or other large distributor
first. You may have to have heavier sheet re-rolled to get 1/2 hard
304.

If you want to cut out the distributor there are custom rolling mills
and converters around. (One of my customers has several rolling mills,
but they run more exotic stuff and probably wouldn't be good fit.) A
quick google search turned up too much extraneous junk to be helpful
-- I'm sure Thomas Register would work better.

Excellent! 304 halfhard right on the page!
But how did you get this?
I just now searched on "Stainless Steel" on Thomas, and then refined the
many results with "304", and no CADA!

I don't remember exactly, some combination of jargon like:
stainless steel converting rolling slitting
I may have got to Thomasnet by searching that string on google.

304 is the "18-8" stainless S30400
there is a 304HN (non standard)...
HH is High strength; oxidation resistant to 1090C (2000F) most widely used
mostly used with cast stainless steels.

Try Penn Stainless Products
All they do is stainless, biggest supplier around here and not too far
from NYC.
Thank You,

One of the first places we tried, no go.
Ned found one, hopefully they have the item at hand.
Thomasnet.com yields about 250 SS sheet companies, and strangely, altho CADA
was not among them, altho they do pop up for plain SS.
Apparently, Thomas' tag file or whatever is not as complete as what google
will find, as Ned alluded to, so altho it is certainly a more
concise/concentrated directory, it does not appear to be so hot for finding
specific items, which google will find. Inneresting.....
