IMPACT-TOUGHNESS INVESTIGATIONS OF DUPLEX

Duplex stainless steels are very attractive constructional materials for use in aggressive environments because of their several advantages over austenitic stainless steels.Duplex steels have excellent pitting and crevice corrosion resistance,are highly resistant to chloride stress-corrosion cracking and are about twice as strong as common austenitic steels. IMPACT-TOUGHNESS INVESTIGATIONS OF DUPLEXThe impact toughness of the commercial 2205 duplex stainless steel and the higher-alloy super-duplex 2507 steel was investigated.Both steels were submitted to the ageing treatment in a temperature range between 500 °C and 900 °C with the exposure times of 6 min,1 h and 10 h; in addition,light microscope examinations,hardness measurements
