Removing rust from stainless fridge

oh for crying out loud.

300 series Stainless is non-magnetic.

400 series Stainless is MAGNETIC.

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.
