I got in a hurry on a job, and had to run 10-mi to the scrapyard for some
heavy 4" angle, rather than driving the 80-mile round-trip to the only
distributor around. It ended up being some 9.8lb/ft 4x4 angle (so,
pretty heavy angle, 3/8" flanges).

They had only one piece that would suit: It was obviously hot-dip
galvanized (no problem in itself), had cut ends (after galvanizing), and
had sat in the yard, in the weather (wet) for weeks to months before I
rescued it.

It welds perfectly with mild steel MIG wire and CO2. Did some test welds
before comitting to all the cutwork I needed to do on it. It made clean,
smooth, STRONG welds that I could not break even bending the piece at the
weld... it just bent there, being just a line-weld, and thinner than the
flange.

'Funny thing, though, none of the few gouges and dings in it had even a
trace of rust. Neither did the cut ends ??? I did some fresh cuts,
exposed them to overnight dew and 85F temps (just to see), and not a SIGN
of corrosion.

Hmmm... I'm not familiar with the alloy. It's obviously NOT any of the
3xx series stainless I often work with, and although those will braze,
and will weld Eh..OK with mild steel wire, they don't usually produce as
strong a weld as the base metal. It's also as strongly magnetic as A36
would be.

My experience has been that when heavily galvanized members like this
show up in the scrapyard, they've often come from power company pull-
downs.

Has anybody worked with a steel that demonstrates these properties? I
think I'd like to find more of it! G

I have not and I have no clue about what it is, but keep in mind that
A36 is a very loose specification, traditionally based on strength and
weldability, with only slipshod nods to ductility, etc. For years, it
didn't even specify the alloy.

And a piece of rolled angle, unless it's a documented grade, could be
almost anything.

I've heard of smearing when galvanized sheet steel is cut with a shear.
Which I'm sure you have too.... From a little bit of searching I found
this that may explain it some:

http://www.astm.org/SNEWS/APRIL_2006...ide_apr06.html

Should make more sense to you with your background... but the gist I
get is that even though you exposed untreated metal the treatment
still close by is somewhat protecting it (shrug).

But that's the steel used for the majority of non-certified structural
shapes. The point is that you can't tell what the alloy is,
specifically, even if you suspect it's A36. If its galvanized, it's
nothing fancy, and A36 or some other non-grade that's even lower on
the totem pole is likely.

It could contain some nickel, or even some chromium, if it's a random
mess of remelt. It isn't some rust-resistant alloy if it's galvanized.
I'm sure you know that even a broken coating of zinc is somewhat
protective even at 1/8 in. or so from the zinc.

That explains a number of things I know about coatings, but doesn't explain
this. The material is thick enough not to allow smearing, especially when
it's being cut by a saw.

This stuff corrodes (doesn't) like stainless, but welds and cuts like
ordinary structural steel! It's not a problem... but an opportunity to
learn something new. FWIW, even the saw-cuttings don't rust!

Any chance that scrapyard, or any other within whatever your

x-ray fluorescence analyzers that will tell you the composition? Or is
there a 4 year college nearby? If so, call the chemistry department and ask
who teaches the undergraduate instrumental analysis course and when they
have their office hours and pay them a visit with a sample they can use in
the course as an unknown, along with an appropriate beverage :-). If those

If you get serious about finding the contents of a metal (~$60 =
serious), try the yellow pages under, I believe, labortories, for
a company that tests material. The pertinnent test is labeled a
"metals test". This is a spark with some spectrum analysis equipment and
the ability of determining what metals and at what concentration exist
from the various metalic signatures.
It's been about 10 years since I had one of these test made but my

I can assure you it did, Ig. I dug it out of wet dirt; One end was
exposed (which was how I found it), the other end almost 3" below the
surface! The soil was thoroughly-compacted around it. It's been soaking-
wet here for months; rain almost every day, and temps in the mid 90s.

Besides, the 'dew test' I gave it would have rusted any common structural
steel overnight. Even when bare steel things stay 'dry' here, they rust
overnight if not in an AC'd environment! It's Florida. G

My guess is that it is one of the structural steels and the fact that it does not rust is because it is hot dipped galvanized. After all why would they have galvanized it , if it would not rust without the galvanizing. My wild guess is that it is something like A709-HPS70W or A852.

If you can not get an analysis at your local college, let me know. The local scrap yard has a XRF analyser and I think I could get them to test a sample. The sample would have to have the galvanizing removed.

Good story. My wife, who was raised in central Illinois and who spent
summers on her grandparents' farm, said that she was never afraid of
the pigs. She was afraid of the chickens. It was their beady little
eyes and the aggressive roosters that scared her.

If you saw a comparison with Bonkers, the difference is that
clobbering him with a 2x4 wouldn't stop him. He has no sense in that
regard. You just have to keep whacking him.

But he makes himself such an easy target that it's not very
challenging. It's just a pain in the neck.

Which goes show that I am some what smarter than a rooster and jon is
somewhat dumber, as he keeps coming back for more :-)

What is shows is...

That you invoke comparisons with annoying and biting little animals.

Don... freshly-cut ends and ground areas do not rust, either! That was in

So if the fresh cut ends do not rust, why did they bother to galvanize it?

I'm interested to see what Lloyd's analysts say, but a couple of
points: First, galvanizing prevents rust not, primarily, by forming a
barrier, but by creating a galvanic cell with the ferrous metal, and
the galvanic protection can extend for 1/8" or more into cut areas.
You can really see this on marine hardware that's been nicked up. Even
exposed to salt water, those bare spots and edges of steel don't rust
much.

Second, your point is the one that prompted me to write that
(unwelcome) post to Lloyd. They don't galvanize rust-resistant alloys.

I'm betting that it's some plain-carbon alloy -- either a clean piece
of mild steel, as Iggy suggested, or, much more likely just based on
what simple structural shapes are usually made of, some loosely
specified structural alloy (A36, etc.). It could also be Chinese or
American re-melt junque -- one of the non-grades of scrap re-melt,
like the railroad rails used for bedframe steel, or the dregs used to
make coat hangers.

Most structural steel is pretty much crap, to a machinist or a
fabricator.

Umm.... If I knew that, then I'd not have asked!

I'm going to do another 'wet' experiment, this time with salt in the wound.
It could be this stuff was prepared for a marine environment, although I
don't recall the use of gavanizing from when I was in the Navy.

Work boats often have galvanized fittings. Yachts are stainless and
bronze. Small pleasure boats have a lot of aluminum.

The navy goes its own way. g

Well... got out to the shop this a.m. to find something different.

Last night, I sparked out a piece, and it looked for all the world like
just ordinary structural steel. A piece of A36 next to it made the same
sparks... BUT... for a long time (a couple of seconds of grinding...) no
sparks.

So today, I took it back in the shop, mic'd a flange, then ground lightly
just until I saw the first sparks, and mic'd it again. There's darned-
near 15 mils of zinc on this stuff!

Further, I had treated a cut end last night with potassium nitrate/water
slurry. This a.m. there WAS some visible rust on the cut surface. The
untreated cutoffs I left out in the dew, now, for two nights are still
pristine.

So, even though these flanges are about 3/8" thick, I guess I'll have to
go with Ed's surmise that the 'galvanic cell' process is keeping the cut
edges from rusting, unless otherwise accelerated to do so.

Huh! I guess I just got a lesson in how good at its job GOOD galvanizing
can be!

Maybe the soil contained some rust inhibitor that came from the scrap.
Were other cut ends rusty?

Everything in the yard but this one piece and a piece of 300-series were
rusted all to hell. And my cut-ends that were not abused with the nitrate
have still not shown a trace of corrosion.

I found some references to using an aluminum zinc alloy for coating as well as a reference to a iron zinc alloy for coating. But did not find anything that compared those alloys to plain old galvanizing.
