Abstract
AISI 441 stainless quality steel is a material with high thermal conductivity and suitable for hot working conditions. Due to these properties, it is widely used in the automotive industry, exhaust systems and heat exchangers. AISI 441 is an alloy specially produced for these applications. Titanium and niobium additions prevent grain growth and segregation at high temperatures while increasing pitting corrosion resistance. The relatively high niobium content provides oxidation resistance at high temperatures. Due to its high chromium, titanium and niobium content, it can show faster secondary hardening than other ferritic grades. Therefore, thermomechanical process parameters require more precise adjustment. In this study, the parameters of cold rolling, continuous heat treatment and pickling processes of AISI 441 were investigated. The mechanical properties and corrosion resistance of the produced alloy were investigated.
