These applications can include food handling/processing (i.e., kitchen sinks, cutlery), medical instruments (i.e., thermostats), hardware, appliances, and structural/architectural uses (i.e., bridges, airport roofs).
Unlike ordinary steel, stainless isn’t prone to corrosion, rusting or staining from water exposure – giving it many versatile applications. The most common of these steps include hot rolling, cold rolling, annealing, descaling/ pickling, cutting and finishing. You can have everything from stainless steel tubing and stainless steel pipes to a stainless steel bar and stainless steel sheet.ĭepending on which grade or shape is being produced, a piece of stainless steel may go through some processing steps multiple times before reaching the desired appearance or characteristics. Stainless steel also comes in many different shapes and dimensions. There are more than 100 grades of stainless steel – most are classified into five groups in the family of stainless steels: The exact composition is strictly measured and assessed throughout the alloying process to ensure the steel demonstrates the required qualities. Other elements can be added to increase corrosion resistance (nickel) and formability (molybdenum). This type of steel also contains varied amounts of other elements such as carbon, silicon and manganese. Once stainless steel is put into service, it does not need to be treated, coated or painted.īesides resistance to corrosion, stainless steel is known for its: This layer prevents corrosion from occurring on the steel surface the greater the amount of chromium in the steel, the greater the corrosion resistance. The chromium content produces a thin chromium oxide film on the steel’s surface called a passivation layer. Stainless steel is an iron alloy that has a minimum chromium content of 10.5%.
