U.S. Highway transportation of liquid chemicals has depended upon austenitic stainless steels (316 and 304) since the 1940`s. This paper will compare these austenitics to the duplex stainless steels (UNS S31803 and S32205 both commonly known as 2205 and UNS S32304 commonly known as 2304) from various aspects such as: composition, mechanical and physical properties; corrosion resistance; design, manufacturing and welding of vessel; heating panel application on the bottom of the vessel; surface finish; DOT Regulations; and cost. Some actual experience with 2205 will be explained.
