AISI 329 (S32900) stainless steel is a duplex stainless steel with high yield strength, up to twice that of austenitic stainless steel.

329 duplex stainless steel has good pitting corrosion resistance, crevice corrosion resistance, oxidation resistance and stress corrosion resistance in chlorine containing water. It is a heat-resistant steel alloy.

329 stainless steel is a kind of high alloy duplex stainless steel. It is often used in heat exchanger and chemical industry in chlorine environment.
