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.

Re: Removing rust from stainless fridge

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?

Why are autos better...??? Revolvers can be shot fast too..:banger

says who?

As for the cleaning question, there is only one person qualified to answer that question and he is unfortunately dead

Re: Removing rust from stainless fridge

Good reading - test with magnet.

Stainless steels are a very broad group of metals. The name was adopted as a generic term for steel alloys with a minimum of 10.5% chromium. The chromium gives the steel its 'stainless' properties - essentially corrosion resistance. On the surface of the metal, a very thin chromium-rich oxide layer is formed which is inert - i.e. it prevents the steel from rusting. The advantage of stainless steels over plated steels is that, if scratched or damaged, the steel will 'self-repair' as a new oxide layer is formed. In plated steels, scratches in the plate will often lead to corrosion of the steel underneath.

Stainless steel wrenchIn general, the higher the proportion of chromium, the stronger the corrosion resistance of the steel. In addition to chromium, other metals are added to give the steel particular properties such as strength and malleability. Specifically nickel is used to strengthen the oxide layer.

As for whether they are magnetic, the answer is that it depends. There are several families of stainless steels with different physical properties. A basic stainless steel has a 'ferritic' structure and is magnetic. These are formed from the addition of chromium and can be hardened through the addition of carbon (making them 'martensitic') and are often used in cutlery. However, the most common stainless steels are 'austenitic' - these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it non-magnetic.

So the answer is yes, the magnetic properties of stainless steel are very dependent on the elements added into the alloy, and specifically the addition of nickel can change the structure from magnetic to non-magnetic.

Re: Removing rust from stainless fridge

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.

Re: Removing rust from stainless fridge

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.
