Stainless steel are iron alloys with a minimum of 12% chromium.Other alloying elements are added to enhance their structure and properties such as formability,strength and toughness.
The main requirement for stainless steel is that they should be corrosion resistant for a specified application or environment.The selection of a particular "type" and "grade" of stainless steel must initially meet the corrosion resistance requirements.Additional mechanical or physical properties may also need to be considered to achieve the overall service performance requirements.
