Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an alloy of iron that is resistant to rusting and corrosion. It contains iron with chromium and other elements such as molybdenum, carbon, nickel and nitrogen depending on its specific use and cost.

Stainless steel is a popular material because it doesn’t corrode and break down easily like other metals. But stainless can develop rust spots, especially if your sink: Is close to heat sources such as the stovetop or dishwasher. Is frequently used for hot water or acidic cleaning products. Has scratches on its surface that trap moisture under the ...
Yes. The black color on stainless steel is typically the result of a discoloration process called “passivation” – an oxidation reaction that occurs between metal and oxygen in water or air to create compounds such as magnetite, FeO(OH). Other factors can contribute to this phenomenon such as heat treating and chemical composition.
The blackening of steel is a result of the formation of an oxide layer on the surface of the metal. This oxide layer can be colored from light brown to black, and it forms as a protective barrier against further corrosion. In some cases, this oxide layer can be so thick that it obscures the underlying metal entirely.
When oxidized, the oxide that forms on stainless steel is black. The color can vary depending upon how long it has been exposed to air and/or water and at what temperature. There are a variety of other factors which impact this oxidation process as well.
Black oxide is a safe and effective finish for stainless steel, as long as it is performed by a reputable black oxide supplier. The process involves submerging the parts in a vat of hot black oxide solution, which creates a hard and durable finish.
No, black oxide is not rust proof. It does, however, offer some protection against corrosion. The black oxide layer will slowly corrode over time, but it will protect the underlying steel from more severe corrosion.
Iron oxide, the main component of rust, is black. When rust forms on steel, it’s because oxygen has combined with the steel to create iron oxide. The rate at which rust forms depends on a number of factors, including the presence of moisture, the type of steel, and the air quality.
The black oxide coating is very durable and strong. It can be a suitable replacement for paint as it resists scratching, chipping, rusting. The black fade will not chip or peel off like other coatings such as paints which make it resistant to wear and tear from daily use.
This is a common question many people ask when they first see this phenomenon. The answer to the question, “why do some screws turn black” is simple: corrosion. Corrosion happens when metal reacts with oxygen or moisture in the air and causes all kinds of damage to material surfaces. This can be seen on stainless steel as it turns black when it oxi...
The black oxide process is a passivation treatment that can be applied to steel made from chromium and nickel. This process oxidizes the surface of the metal, producing a layer that will prevent corrosion if properly maintained. It also gives stainless steel its distinctive matte gray appearance.
