Installed march 06 and already peeling. They are supposed to be stainless but are rusting bad.The bolts were galvanized and instantly rusted,I had to put on black bolts.Does anyone else have these doing the same thing

 

Contact them and ask..rather, Insist on a replacement.[:@]

I got my solid stainless hooks from StallionCustoms..They are real stainless too

 

They are pretty good in replacements
I dealt with them before.

 

Although it does look like you have cheap parts, and a replacement is in order, be aware that stainless steel will rust, epecially if exposed to corrsive elements like salty road grime.

 

I thought the whole point of Stainless Steel was that it doesn't rust. I thought it doesn't oxidize? I had a few stainless steel things before, and they have rusted eventually.

Stainless Steel out, Chrome in ;-)

 

Stainless steel


From Wikipedia,



In metallurgy, stainless steel (inox) is defined as a ferrous alloy with a minimum of 10% chromium content.[1] The name originates from the fact that stainless steel does not stain, corrode or rust as easily as ordinary steel. This material is also called corrosion resistant steel when it is not detailed exactly to its alloy type and grade, particularly in the aviation industry. As such, there are now different and easily accessible grades and surface finishes of stainless steel, to suit the environment to which the material will be subjected to in its lifetime. Most famous uses of stainless steel are the everyday "spoons" or "watch straps".

Stainless steels have higher resistance to oxidation (rust) and corrosion in many natural and man made environments; however, it is important to select the correct type and grade of stainless steel for the particular application.

High oxidation resistance in air at ambient temperature is normally achieved with additions of a minimum of 13% (by weight) chromium, and up to 26% is used for harsh environments.[2] The chromium forms a passivation layer of chromium(III) oxide (Cr2O3) when exposed to oxygen. The layer is too thin to be visible, meaning the metal stays shiny. It is, however, impervious to water and air, protecting the metal beneath. Also, when the surface is scratched this layer quickly reforms. This phenomenon is called passivation by materials scientists, and is seen in other metals, such as aluminium. When stainless steel parts such as nuts and bolts are forced together, the oxide layer can be scraped off causing the parts to weld together. When disassembled, the welded material may be torn and pitted, an effect that is known as galling.

Nickel also contributes to passivation, as do other less commonly used ingredients such as molybdenum and vanadium.

Stainless steel's resistance to corrosion and staining, low maintenance, relative inexpense, and familiar luster make it an ideal base material for a host of commercial applications. There are over 150 grades of stainless steel, of which fifteen are most common. The alloy is milled into sheets, plates, bars, wire, and tubing to be used in cookware, cutlery, hardware, surgical instruments, major appliances, industrial equipment, and building material in skyscrapers and large buildings. See "Use in sculpture and building facades", below, for more.

Stainless steel is 100% recyclable. In fact, over 50% of new stainless steel is made from remelted scrap metal, rendering it a somewhat eco-friendly material[citation needed].


Corrosion

Even a high-quality alloy can corrode under certain conditions. Because these modes of corrosion are more exotic and their immediate results are less visible than rust, they often escape notice and cause problems among those who are not familiar with them.


Pitting corrosion

Passivation relies upon the tough layer of oxide described above. When deprived of oxygen (or when another species such as chloride competes as an ion), stainless steel lacks the ability to re-form a passivating film. In the worst case, almost all of the surface will be protected, but tiny local fluctuations will degrade the oxide film in a few critical points. Corrosion at these points will be greatly amplified, and can cause corrosion pits of several types, depending upon conditions. While the corrosion pits only nucleate under fairly extreme circumstances, they can continue to grow even when conditions return to normal, since the interior of a pit is naturally deprived of oxygen. In extreme cases, the sharp tips of extremely long and narrow pits can cause stress concentration to the point that otherwise tough alloys can shatter, or a thin film pierced by an invisibly small hole can hide a thumb sized pit from view. These problems are especially dangerous because they are difficult to detect before a

 

Depends on the grade of Stainless Steel. Stainless Steel AISI 303 or 304's will eventually rust, that is why they are not meant for corrosive environments specially high salinity conditions. Stainless steel AISI 316 would be best but is also alot more expensive and is harder to machine.

 

All stainless steels can be "seeded" by fileing, cutting, drilling or having them come into contact with non-stainless steels. Where the high carbon, non stainless steels come into contact with the stainless steel is where the stainless steel will start to rust.
