... precipitating at the grain boundary, penetrating cracking was observed at the "T" shaped welded resulted in a narrow belt lack of chromium nearby known as joint between the cylinder and right head of the vessel. After sensitization. The corrosion resistance of the austenite getting rid of the penetrating crack...

...Abstract Abstract Austenitic materials with high sensitization resistance and high temperature strength are required for furnace and reaction tower of desulfurizing plants in the petroleum refinery industry. For these requirements, a new steel (LowC-18Cr-11Ni-3Cu-Mo-Nb-B-N) has been developed...

... were investigated. The research results show that the corrosion rate markedly increases and pitting potential rapidly decreases with increasing temperature and Br − ion concentration. The pitting resistance of SAF2205 stainless steels is superior to AISI316L. For sensitized AISI316L and SAF2205...
