Stainless, acid- and heat-resistant steels have an excellent resistance  to corrosive media, provide high strength and elongation, and high  thermal stability. Stainless steels are commonly divided into five  groups: martensitic stainless steels, ferritic stainless steels,  austenitic stainless steels, Duplex (ferritic-austenitic) stainless  steels, and precipitation-hardening stainless steels. Because of their  outstanding properties, they are used in chemical industry, in  mechanical engineering, in food industry, and in the energy, medicine,  traffic and transport industries.
