Super Duplex S32750 Vs. Austenitic Steel
S32750 super duplex stainless steel plate is supplied in hot-worked and solution annealed state. The pitting resistance equivalent number (PREN) is >40, providing better pitting and crevice corrosion resistance than austenitic steel in almost all aggressive media. It also has a lower thermal expansion coefficient and higher thermal conductivity and strength than austenitic steel.
