Removing rust from stainless fridge

What was that I said in my original post??

Still LMAO here.

C ya.
Ok its not rust, lets call it corrosion.

Let's not confuse it with Oxidation.

I think I need a rusty nail after all this!

While you're at it make one for me too, but leave out the Drambuie please.

Do you still want a twist of lemon?

It's true. If stainless steel didn't rust, it'd be nifty for use inside the body (pins, artificial joints, etc.) Unfortunately, it will oxidize inside the human body.

Oh no.
Say it ain't so.
You did not use the word Oxidize, did you?
Let's get off on another one (debate).
Oxidation and Corrosion are not one and the same, although often confused.

I'm not picking on this post in particular, but it is a good starting place for trying to summarize the correct info that is sprinkled throughout this thread.

The discussion here is being hampered because "rust" is a laymen's term for one particular form of corrosion. Steels (not stainless) are susceptible to a general surface corrosion which forms iron oxide. That's the reddish-brown stuff we call "rust."

Stainless steel forms a very thin oxidation layer on surface which "passivates" or protects the metal from further general corrosion. The layer is kinda fragile, so it can get disrupted by fingerprints, water drops, etc. These can be removed with common stainless cleaners.

Stainless can corrode in other ways. It is susceptible to pitting corrosion caused by chlorides like the salt in your sweat. See the photo of the pistol trigger guard in a previous post.

I'm an appliance engineer and I can tell you stainless appliances sell well, at a premium price. But, I wouldn't recommend them to a friend unless they were prepared to constantly polish and polish them. They aren't practical in a kitchen environment.

I am sorry, but this is not an accurate statement. Surgical stainless steel is used internally. I have had stainless steel Harrington rods in my back for 25 years.
Stainless steel plates, screws and wire are also used. Surgical stainless steel is used in joint implants and heart valves as well.

Stainless or not?

Rust never sleeps.

There are many kinds of stainless steels. The cheapest ones are not very corrosion resistant. The ones that are are also expensive. Which do you think are used in appliances vs. implants?

Depending on the Hardness of the SS will depend on how corrosion resistant it is. It all depends on the combination of metal alloys used in the particular product.

It is non-magnetic.

oh for crying out loud.

300 series Stainless is non-magnetic.

400 series Stainless is MAGNETIC.

Bobarian -

Research martensitic steel vs austenitic steel.

Your rods would have been 316LVM Steel.

The nickel/chrome/molybdenum alloys are also used for orthopaedic implants as aids in bone repair, as a structural part of artificial heart valves, and other implants. Immune system reaction to nickel is a potential complication. In some cases today titanium is used instead in procedures that require a metal implant which will be permanent. Titanium is a reactive metal, the surface of which quickly oxidizes on exposure to air, creating a microstructured stable oxide surface. This provides a surface into which bone can grow and adhere in orthopaedic implants but which is incorrodible after implant. Thus steel may be used for temporary implants and the more expensive titanium for permanent ones.

Did you see the part about ""INCORRODIBLE AFTER IMPLANT""?????

You wanna compare implants, let's go. I have titanium in my jaw, my shoulder, my hip and my foot. They are PERMANENT.

Martensitic Steel (Surgical) is used as a healing AID...not as a PERMANENT solution.

One of many reasons why the Harrington rods became obsolete in the 90's - Slight problem with people's reaction to the nickel content of the steel and all.....

This “implant grade steel” as John calls it, is not impervious to degeneration and it would be best called “stain less” steel. Mixtures of these metals are used for short term medical implants but are not considered for longer term (20 to 30 years). In cases where the implants are to be “permanent”, titanium alloys are preferred.
