| DUPLEX STAINLESS STEEL | |||||||||||||||||
Duplex SS is having high corrosion resistance and the excellent mechanical properties. Firstly, the chemical composition based on high contents of Cr and Mo, improves intergranular and pitting corrosion resistance, respectively. Moreover, additions of nitrogen can promote structural hardening by interstitial solid solution mechanism, which raises the yield strength and ultimate strength values without impairing toughness. Secondly, the two-phase microstructure guarantees higher resistance
to pitting and stress corrosion cracking in comparison with conventional
stainless steels. |
