Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 10.5% chromium and usually nickel, and may also contain other elements, such as carbon, to obtain the desired properties. The resistance to corrosion in stainless steel results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen. Stainless steel is 100% recyclable, and an average stainless steel object is composed of about 60% recycled material of which approximately 40% originates from end-of-life products, while the remaining 60% comes from.

Stainless steel is used in many everyday objects and plays a prominent role in an array of industries, including energy, transportation, building, research, medicine, food, and logistics. It is aesthetically appealing, extremely hygienic, easy to maintain, highly durable, and offers a wide variety of aspects. The exact components and ratios of stainless steel vary based on the grade requested and the intended use of the steel. Other common additives include nickel, carbon, manganese, molybdenum, nitrogen, sulfur, copper, and silicon.

Stainless steel is manufactured by melting scrap metals and additives in an electric arc furnace (EAF) . The exact temperatures will vary based on the grade of steel created. Stainless steel is a widely employed choice in kitchen equipment of all kinds, as it is durable, long-lasting, and resistant to corrosion. It is also used in the marine sector for small components.
