Stainless steel, also known as inox or inox steel, comprises a range of iron-based alloys with a sizeable chromium content as well as varying quantities of nickel and carbon. Stainless steel is strong and resistant to corrosion. Well-known uses include machinery, pipes and tubes, kitchen counters and ventilation systems that become available during renovation and demolition projects. An alloy will only be considered stainless steel if it contains a minimum of 11-12% chromium content by mass and a maximum of 1.2% carbon. In addition, many stainless steel types contain varying quantities of the elements molybdenum, titanium, manganese, nitrogen and silicon. Thanks to its corrosion-resistant properties, stainless steel is frequently used in the petrochemical and food industries.
