<DIV id=yui_3_16_0_1_1430342083286_2920 dir=ltr>Super Duplex stainless steel is used widely in the off shore oil and gas industry for corrosion in production tubulars particularly for high H2S levels. It has high chromium and molybdenum content. Excellent resistance to inorganic acids especially those containing chlorides. I don't know of any submersible pressure hulls made of Super Duplex stainless steel. It would be expensive.</DIV>
