Roostevabale

Roostevabale, often referred to as stainless steel, is a group of steel alloys that contain a minimum of 10.5% chromium by mass. This chromium content is key to its defining characteristic: resistance to corrosion and rust. When exposed to oxygen, the chromium in the alloy forms a thin, passive, and invisible layer of chromium oxide on the surface. This layer acts as a protective barrier, preventing further oxidation of the underlying metal.

The composition of stainless steel can vary significantly, with different grades offering unique properties. Common alloying elements besides chromium include nickel, molybdenum, titanium, and nitrogen. Nickel enhances ductility and formability, while molybdenum improves resistance to pitting and crevice corrosion, particularly in environments containing chlorides.

Stainless steel is widely used across numerous industries due to its durability, hygiene, and aesthetic appeal. It is prevalent in kitchenware, cutlery, cookware, and appliances, as well as in construction for architectural features, roofing, and structural components. The medical and pharmaceutical industries utilize it for surgical instruments, implants, and processing equipment due to its non-reactive and easy-to-clean nature. Automotive parts, aerospace components, and industrial machinery also frequently employ stainless steel for its strength and corrosion resistance. Its recyclability further contributes to its sustainability profile.
