Stainless steel - possible to solder or weld?

As title

[Dave Plowman (News]

You can weld SS using a MIG and SS wire.

[Jim]

Yes.

Google "silver solder stainless steel"

[nightjar]

Generally, yes, but some grades are more difficult than others. For soft soldering 304 stainless steel, I always used a flux comprising 50% concentrated hydrochloric acid, 25% Bakers Fluid and 25% water.

gareth evans explained :

I have had success with a very aggressive flux, as used by plumbers.

Ta.

What it is, I got one of those nifty devices for opening a boiled egg where you throw the weight down onto the steel cup and it severs the shell with a nice circular break.

No more irritating bits of shell in your teaspoon when eating the egg!

But ... after less than a year, the throwing down of the weight has caused the steel cup to detach.

One of these ...

Throw it down? Or just let it drop? Presumably having done that on can insert a knife and effect a horizontal cut?

[PeterC]

I found that mixing a powder that we used for silver solder and brazing into a slurry with water, cleaning off the SS, applying the slurry and leaving for an hour enabled silver soldering or brazing. I made a cage out of SS strip that could hold a 1.5 li water bottle on the bike (I had 3 bosses on the down tube). The cage withstood probably over a

100 kmiles of touring, so the joins are pretty good.

Even by my standards that's a gadget too far :-)

Quick chop with a knife does it here.

[John Walliker]

Concentrated phosphoric acid is a good flux for soldering stainless steel and doesn't leave a nasty residue. John

[Chris Bacon]

Throw it away and buy some more from ChinaChinaChina.

What sort of stainless steel there are many alloys called stainless steel and some are even ferrous but still do not rust or stain. I know cos I have a magnet. Grin. Brian

[John Rumm]

Are there any stainless steels that are non ferrous?

[newshound]

Brian means "ferritic" (as opposed to martensitic or austenitic).

[jon]

Yes, those used in submarines.

[newshound]

Well, perhaps Brian meant non-magnetic. But AFAIK, submarines are still mostly made from good old fashioned carbon steel, as are (most) surface warships. Presumably they still use degaussing, first introduced in WW2, but perhaps magnetic mines are not the threat they once were.

[Chris Bacon]

Is there *any* non-carbon steel?

[newshound]

Well no, but the carbon level is pretty low in mild steel. I should probably have said carbon-manganese steel, because that's typically what is used when you need a bit more strength as in pressure vessels including submarine pressure hulls. The term carbon steel is also used for steels with sufficient carbon to be hardenable, such as knife blades, also everday tools like hammers, chisels, pliers, etc. In the old days, drills, taps, dies, etc. were made from carbon steel, these days "high speed steels" with alloying elements to give them more "hot hardness" are more common.

who is the entity known as peeler? does it post under any other name, it does not seem to serve any purpose other than annoy every one other than you who I imagine gets great enjoyment.
