Stainless steel is a durable and low maintenance material and is often the most cost-effective choice that boasts a long life span. It is easy to maintain and to keep clean. Stainless steel is corrosion and oxidation resistant for a specified application or environment. Stainless steels are iron alloys with a minimum of 10.5% chromium. Other alloying elements are added to enhance their structure and properties such as formability, strength and cryogenic toughness. These include metals such as nickel, molybdenum, titanium and copper. Non-metal additions are also included such as carbon and nitrogen. Stainless steel is easily and simply maintained, resulting in a high quality, pleasing appearance.
