You can use stainless bolts and nuts, but there are good practices
when doing so, just as everything else in life.
PeterD was saying the stainless rusts when there's no oxygen, and
that's what I was addressing, that you addressed, that I just
addressed. Okay, I'm going to go up on a ladder now, I'm getting
dizzy down here. ;)
SS has a huge tendency to gall......I once screwed together, by hand,
a dry SS short nipple (2" pipe) into a fitting. Only a couple turns
and the assembly almost seized up on me!
The pipe thread was a pipe rough, I didn't us any tape, lube or
dope.....I was just doing a dry fit up.
Stainless on stainless is used VERY frequently........why else would
there be a vast selection of SS bolts & nuts?
galling is a potential problem with SS on SS but the use of proper
plating or lubes will help a lot
PS stop using TV as an uncorroborated source of technical information
........ Oxygen is inseparable from oxidation (rusting).
..... I think it's more likely that moisture was getting into those
hidden areas and staying
first of all the term "stainless steel" though popular & widely used
is not the "correct" term for the material under discussion
the more correct terminology is "corrosion resistant"
btw all "stainless steels" will rust / corrode under the "right"
another little know fact, so called "non-magnetic", 18-8 stainless
steels (typically 300 series) can, when "worked" by certain processes,
in fact, exhibit magnetic properties
I'm late to the party but if they are really concerned about corrosion in
the rebar maybe they should look into getting some of the (fairly) new stuff
called MMFX rebar. It is five times as corrosion-resistant and up to three
times as strong as conventional steel. He could use less steel and it would
last longer than just about any other comparable product. Ameristeel is
advertising a product called "Z-Bar" that is better (per their claim, not
mine) than just plain epoxy coated bars, but I have not been involved with
any project that used this material, so I can't say anything one way or the
other about it.
The main culprits in attacking the rebar, salt and water, don't have
nearly as much effect on concrete. Protecting the concrete would
require protecting large areas, and periodic reapplication of whatever
it was you were using to protect it. The epoxy coated rebar has a
much smaller area (in general) and it's a one shot deal.
Your bones are encased in meat, but you can still break your bones
even through the meat. That's why Wolverine has an admantium skeleton
- I'm amazed I have to tell you this!!!! ;)
My son has been a Logan fan since day 1 and has 100 copies of
Wolverine#1 in Wizard archival bags with boards.
(I only have 1 copy)
Just yesterday he emailed me a picture of a razor he purchased -
Wolverine version, Gillette brand, for keeping nice crisp corners on
those 50's style sideburns Logan sports that the ladies find so
I have a comic collection from my ute. It was interesting to see the
spike in the value of X-Men comics about 12 years ago. It was less
interesting to discover that somewhere along the line a few hundred
comics of mine went missing.
I know guys who's mother/sister/wife/insane female human
threw away the guy's comic book collection when he was
away at work/war/contract job overseas. The guy comes
home and finds his stuff gone and the insane female human
is so puzzled by the often violent reaction. Guys have to
hide their stuff in a locked warehouse or safety deposit
I've have (6) 1/2 boxes of bagged and boarded comics, mainly #1
issues, sitting out in the garage I'd like to get rid of but a cursory
review of the market shows they are worth next to nothing. Maybe
they'll burn well.
And I have thousands of comic cards, complete sets with chase cards,
in archival sheets and binders too.
I sure wasted alot of $$$ in my later ute.
What were you reading/collecting that #1 issues are almost worthless?
I just read what I liked. I actually had a non-lending comic book
library in college to help support my habit. Collected dues and a had
a punch card catalog system and everything. Some of them are worth a
fair amount. I was a little brought down when I started looking into
the values that the ones that disappeared had most of the value. And
also disappointed to see that what should be the most valuable comic I
have in the collection is missing it's cover and worth a tiny fraction
of an intact comic. No surprise there, still disappointing.
I think that is the epoxy (or some sort of plastic) coated stuff. As
they lay it out, somebody has to go spot-treat all the spots where they
weld it or cut it, lest that provide an entry point for water to get
under the protective layer. The spot repairs I see are red, probably to
make it quick to check and see that none got missed. A color like green
would also make any damaged rusty spots jump out at you.
The green stuff is all I ever see anymore used on bridge or parking
garage work around here in salt country. Even see it used on vertical
work, like for exposed concrete on buildings.
Yes, it is epoxy coated rebar, Out in the west they also have an epoxy
coating that is purple. They have different properties in the coating and
are used in different applications.
The "Z" bar I mentioned above is in a Yellow coating.
I "heard" (so it may/may not be true) that a job one time was supposed to
use epoxy coated rebar, but the shop sent black (that is the term we use for
uncoated plain old rebar)) bar instead. The contractor didn't want to wait
for it to be refabbed, so he told the guys to go to paint store, get a can
of green paint, bring it back and coat the bars with that instead...
I'd like to see that, as I've never seen one bent-and then break
because of it.
It would have had to have been bent back and forth quite a bit to have
stressed to the breaking point.
I installed 64 HU28's and 8 HU28-2's yesterday and the only thing that
broke was the skin on the middle finger of my left hand as it crushed
between the edge of an HU28 and a 28oz Estwing waffle face. It made
for a really nifty red splash pattern on the ledger board.
(6) 16d's per hanger - do the math x 28oz.....yes my arm is warped
