Stainless steel minimum 10.5% chromium in stainless steels provides resistance to ~, while 26% chromium provides resistance up to ~. Type 304, the most common grade of stainless steel with 18% chromium is resistant to ~. Other gases such as sulfur dioxide, hydrogen sulfide, carbon monoxide, chlorine, etc. also attack stainless steel. Resistance to other gases is dependent on the type of gas, the temperature and the alloying content of the stainless steel. Properties of a few common grades are liste below. For a comprehensive list please go to "Raccolta di Tabelle Techniche', compiled by Centro Inox, Italy Like steel, stainless steels
Stainless steel grades typically EN1.4913 or 1.4923 are used in parts of turbochargers, other heat resisting grades for EGR (Exhaust gas recirculation) and for inlet and exhaust valves. In addition, common rail injection systems and particularly the injectors rely on stainless steels. Stainless steel has proved to be the best choice for miscellaneous applications, such as stiffeners for windshiel wiper blades, balls for seat belt operation device in case of accident, springs, fasteners, etc. The aft body panel of the Porsche Cayman model (2-door coupe hatchback) is made of stainless steel. It was discovered during early body prototyping that conventional steel could
