In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable (inoxidizable), is a steel alloy with a minimum of 10.5% chromium content by mass.
Stainless steel is notable for its corrosion resistance, and it is widely used for food handling and cutlery among many other applications.

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high-salinity, or poor air-circulation environments.
To reduce staining, the surface of stainless steel must be kept clean throughout its aging process when oxygen reacts with the surface to form a protective chromium-oxide layer. Once this process has taken place, the surface becomes much more resistant to staining.
There are various grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required.
Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by making it easier for more iron oxide to form. Since iron oxide has lower density than steel, the film expands and tends to flake and fall away. In comparison, stainless steels contain sufficient chromium to undergo passivation, forming an inert film of chromium oxide on the surface. This layer prevents further corrosion by blocking oxygen diffusion to the steel surface and stops corrosion from spreading into the bulk of the metal. Passivation occurs only if the proportion of chromium is high enough and oxygen is present in it.
Stainless steel’s resistance to corrosion and staining, low maintenance, and familiar lustre make it an ideal material for many applications. The alloy is milled into coils, sheets, plates, bars, wire, and tubing to be used in cookware, cutlery, household hardware, surgical instruments, major appliances, industrial equipment (for example, in sugar refineries) and as an automotive and aerospace structural alloy and construction material in large buildings. Storage tanks and tankers used to transport orange juice and other food are often made of stainless steel, because of its corrosion resistance. This also influences its use in commercial kitchens and food processing plants, as it can be steam-cleaned and sterilized and does not need paint or other surface finishes.

    Scope for large-bore, single-action revolver?

    I've been kicking around the idea of mounting a scope on a Magnum Research BFR, if for no other reason I haven't done so in the past. I don't scope firearms very often, but if I can, stick with Leupold. Though not sure that is an option in this case. Any recommendation? Thanks. :)

    What'cha reading?

    So, I just wrapped up the three novel series, dubbed "The Hot War", by Harry Turtledove. The books in the series are Bombs Away, Fallout, and Armistice. Not a bad summer read. Deathless prose? No, but a real treat for the history nerd, and just a delightfully stimulating set of books in the...

    Marlin 1894 CST Questions

    So, I am finding this one interesting: Stainless steel, .357 Magnum, 8+1 magazine capacity, threaded for a can, and weighing in at 6½ pounds. The point of acquiring one would be to run it suppressed with a 9㎜ silencer that is currently in the battery. Questions: Anyone know what the...

    Stainless Steel Provider

    Sorry for the silly title, amigos, it is from an old Revco song. Now that the little people in this household have stopped interrupting me with the noise and paper airplanes, I can perhaps ruminate on the latest project. On that point, a NIB, stainless steel, .44 Magnum, Winchester 92-based...

    Telling a Walther PPK/S to Can It

    I keep having the urge to suppress our Walther PPK/S (in .380 ACP / 9×17㎜ Corto). This handy little pistol: Two part question: What aftermarket / custom threaded barrel? What super-duper small, micro-can for said? Many thanks friends.

    You're Gonna Need a Bigger Boat ...

    Today's Forgotten Weapons covered the Greener Harpoon Gun. Said was featured in the 1975 classic Jaws. Anyway, I found it a neat video as it covered the specifics of this rather unique weapons system, so I figured I'd pass it along.
