4130 - bad news...

This message came in today from one of Tailwind gurus.

This is NOT good news, so I'm considering it as bad news.

I just talked to Charllie at Dillsburg concerting 4130 sheet. I now
call weekly for the latest update. According to Charlie (and I agree)
what we are seeing with 4130 is endemic of the entire steel supply.
Over the years, America's ability to manufacture our own steel has
steadily diminished to the point where we are now dependent of CHINA
for 4130. They can charge whatever they want and deliver according to
their own convenience.

Out sourcing of our ability to produce the products we need is a
disaster that threatens everything. Terrorists, who want to see the
end of our country, don't need to do a thing except wait. Our own
stupidity, greed and laziness will do the job for them. Jerry

Having done a bit of work with the steel industry, I have to point out
a couple of common fallacies in the above.

#1, there is absolutely no problem in America's ability to manufacture
4130 sheet (or any other alloy). The limitation is not in the ability
to make it, but rather in the lack of demand. There simply isn't
enough demand to warrant making 4130 sheet, even in the modern, highly
successful and highly profitable mini-mills such as Nucor.

#2, regarding the Chinese, they're neither "charging what they want"
nor "delivering according to their own convenience". That's why you
don't see new stock being delivered at any price. They're not
interested in the 4130 sheet niche either.

Looking on from faraway Europe I can only agree.
Exactly the same thing is happening here
(but also with wheat from the US...)

Some call this the advantages of the worldwide market...

The only thing we have to do to stop the outsourcing is require all
companies to obey the same environmental and workplace safety laws that
companies struggle under here (here being any so called '1st world'
nation). The list of regulations we dump on someone when they seek to
employ another makes the FAA look libertarian. If the Chinese operators
had to provide even half of the safety measures that are required here,
they could not hope to compete. But it's a lot cheaper to produce steel
when you can clog the air as we did in the 50s and 60s, and cheaper to
produce chemicals when you can run the waste out a pipe and into the
stream out back.

Stand up for workers rights and environmental
protection...EVERYWHERE...not just the US/Europe.

I'm just glad I bought all the sheet I will need two years ago. Where
are you and how much do you need?

The Chinese are having a HUGE building boom in the free trade zone. This is
driving the price of all steels sky high and many other materials used in
building. With everyone from Boeing to Intel moving there what can we expect?
(Intel is moving manufacturing AND R&D).

It is a basic supply/demand problem.

Rather than a lack of demand I think it might be more accurate to say
that there is more demand for other kinds of steel products. This is
because the production capacity is pretty well maxed out. If it were
not there would be someone trying to find an unfilled niche.

But no matter the reason - there is no 4130N available - and IMHO
there probably won't be for maybe several years.

So it looks like we need to find a substitute. I've been doing some
looking for the last couple of months but I'm no metallurgist and most
of my time has been spent educating myself in the ways of steel. So
far my local steel store has not been able to get anything I have come
up with unless I want to buy a whole truck load. I don't/can't.

Anyone have some opinions on a suitable substitute?

Well, now that you mention it, this does put the 4130/DOM(?)
argument in a slightly different light.

Anybody wanna say, "I told you so"?

I was under the impression that 4130A (annealed) sheet was still
available, the only difference between that and 4130N (normalized) being
the heat treatment. It should be possible to have parts made from "A"
heat treated to "N" condition, right?

Also, the last time this was discussed there was only a shortage of
4130N sheet. Has that now spread to tubing as well?

One solution is to normalize your own sheet - apparently it IS
possible to get tempered 4130.

But I've been wondering if the solution isn't High Strength Low Alloy
(HSLA) steels. I know nothing about their weldability compared to
4130, but I do know that tons and tons of the stuff are used in cars
and industrial equipment.

That's where I think homebuilding and experimental aviation as a whole
needs to start looking.

Even the annealed stuff is in short supply. Last time I checked with
Dllsburg (about 10 days ago) he sad - maybe - in a month.

This is where my wanderings have lead me. Welding could be different.

I know most auto manufactures prohibit gas welding the stuff. MIG or
TIG is OK and brass should not be a problem as long as the temp stays
low enough. Some of the HSLA's apparantly are highly corrosion
resistant as well.

ASTM A606, A1011, A1008 and ASTM A715 are specs of some steel that
might work. Supply should not be a problem in thicknes between .020"
and .125"

Brazing high strength alloy steel components of automotive bodies is
STRICTLY FORBIDDEN. Mig and tig are acceptable if done to
specifications - spot welding is most common.
