Who invented stainless steel!

[Moparfiend]

From bottle washer to the inventor of stainless steel we owe him a lot!

Similarly, chrome vanadium steel was pioneered by Henry Ford in 1908.

The problem I have with "stainless" steel is.....

it stains

...and once it stains, it's HELL to try and remove that stain.

Yeah, my knives are rusting and still need polishing or sanding and polishing. And I believe there’s so many different grades of stainless the super high chromium doesn’t rust as much right?

My mom's house had a stainless "splash panel" in back of the stove.

Just the food splashes stained it...and would not come off.

So maybe not so stainless!

They have that problem with the Gateway Arch in St. Louis.

Study finds Gateway Arch is structurally sound, though stained

All those new "stainless" appliances also fingerprint REAL easy.

...and that ain't no picnic to get off, either.

Maybe should have been named “ rust less steel”

It's corrosion resistant, depending on the mix

Yes many different grades of stainless steel. Depending on the amount of carbon in it, it can rust. The more pure it is the less it will rust or stain. You can check this with a magnet. High grade stainless steel won't hold a magnet.

That’s sort of an oversimplification.
There are a huge number of stainless alloys.
A couple of generalities. I’m going by my self admittedly horrible memory, so don’t take the numbers to seriously.
300 series is non magnetic and has to be roll hardened (work hardens.)
400 series is magnetic and can be heat hardened. These are your cheap knife blades and such.

There are a lot of different types of each that have different properties.

They are always developing new stuff too.

EVERYTHING oxidize. Even gold. Just takes longer.

Rust never sleeps.

An interesting thing I learned when I worked at the steel mill. They would have staff give lectures about technical stuff from time to time. A lot of it was way over my head but it could still be interesting.

My bosses boss was a chemist. I attended one of his lectures, and learned that the reason steel rusts is that iron oxide is the chemical state that uses the least amount of energy at rest, so iron is constantly trying to return to that state.

Or something like that. I flunked HS chemistry lol.
