Special steel| 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. |
