We are one of the preeminent manufacturers and suppliers of  Duplex Stainless Steel 329 Round Bars. Immensely useful for construction industries, these bars are offered by us in various sizes and finishes to choose from. Complying the industrial norms, our round bars last for long duration and available in bulk quantities at most reasonable rates.

Duplex Stainless Steel 329 was one of the earliest duplex steel which is reflected in its higher permitted carbon content. Its resistance to pitting (PREN about 32) and to crevice corrosion is below that of super duplex steels, therefore use in seawater is limited. Exposure to moderate and high temperature and less rapid cooling may cause embrittlement. Accordingly, design stress values in ASME II do not extend above 260°C for S32900. Impact values are high at room temperature. However, the proportion and orientation of ferrite in welds and base material may significantly affect toughness at subzero temperatures.

Duplex Stainless Steel 329 also conforms, or is similar to EN/DIN 1.4460 and 00Cr25Ni5Mo2  /  SUS 329J1  /  AISI 329  /  UNS S32900  /  Brands SS44  /  SS 2324  /  Din X8CrNiMo27-5  /  ASME SA268  /  ASTM A268  /  ASTM A511  /  SS 14 2324  /  SIS 14 2324  /  453S

Duplex Stainless steel 329 can be used for heat exchangers, chemical tanks, refineries, shafts (marine, etc) pressure vessel parts, flanges, fittings & pipes for the oil and gas industries and offshore technology, paper industry, compressor parts and seawater desalination plants amongst many other applications.
