Stainless steel is a steel alloy with substantial composition of nickel and chromium. Unlike ordinary steel, stainless steel is resistant to corrosion, this characteristic alone makes it a low maintenance material suitable for many applications. Stainless Steel is often used for industrial piping, construction structures, kitchen ware and etc. Another advantage of stainless steel is its fabrication properties, especially with austenitic grade Stainless Steel as it fits easily into standard fabrication methods. Austenitic stainless steels have high ductility, low yield stress and relatively high ultimate tensile strength.
