Aluminum Coupled with Stainless Steel (Atmospheric Exposure) No significant difference was visible between the aluminumstainless steel coupled and uncoupled materials after 1 month and 3 months of exposure. This was expected because both aluminum and stainless steel form strong passive oxide layers in the presence of oxygen in the atmosphere.

The other classes are: ferritic, precipitationhardening, martensitic, and duplex. Ferritic stainless steel contains approximately 12 percent chromium and virtually no nickel. Since nickel is an expensive alloy, sinks made from ferritic steel are less costly, more brittle at lower temperatures and more gray in color.

Stainless steels cannot be passivated unless the steel surface is clean and free from contamination and scale from welding operations. Scale may need to be removed first by ''pickling'' (or mechanical abrasion) and although the surface of freshly pickled stainless steel will normally be immediately passivated once the pickling acid has been washed off, it is important not to regard these two treatments as the same.

Dec 18, 2015· Nickel and molybdenum make stainless steels expensive, and there is a cheaper way to keep steel from rusting: plate it with zinc, a process sometimes called galvanizing. This can be done either by dipping the steel in molten zinc, or, more appropriate for climbinganchor hardware, applying the zinc through an electrical process.

Both solid and hollow bars are shown for the stainless steels. The hollow bars represent actively corroding stainless steel, which has a different potential then passive (not corroding) stainless steel. In most applications, where dissimilar metals are combined, the passive (solid) bar should be used to determine the position of the stainless steel.

Stainless steels which have been brushed with a wire wheel made of ordinary steel will have a surface contaminated by tiny fragments of regular steel, which will rust. The oxide layer on the stainless steel body will be imperfect, and oxidation will progress thru and under the passive oxide until the whole stainless steel is corroded.
