Chanathip Nickel Alloys & Plates of Bangkok also manufactures Duplex Stainless Steel S32205 bars, often considered equivalent to S31803/2205 but with tighter control on certain elements. These bars are available in similar shapes: round, square, and flat, with diameters up to approximately 200 mm. They come with a high finish, certified heat treatment, and comply with ASTM, EN, and ASME standards. We focus on producing bars that provide slightly better corrosion resistance and material consistency for customers needing improved performance in more aggressive chemical and marine environments.
The chemical composition of S32205 is similar to S31803, with around 21-23% chromium, 4.5-6.5% nickel, 2.5-3.5% molybdenum, and nitrogen ranging from 0.14-0.20%. It has the same limits on carbon, phosphorus, sulfur, silicon, and manganese, with slight adjustments for better control of nitrogen and possibly iron content. Mechanical properties include a tensile strength of approximately 620-660 MPa minimum, yield strength around 450 MPa, and minimum elongation of 25%. The hardness does not exceed 290 HB. This alloy shows good ductility and toughness, with strong resistance to stress corrosion cracking, pitting, and general corrosion, especially in chloride-containing environments.

S32205 bars are used in situations requiring slightly greater corrosion resistance compared to standard S31803. They are suitable for exposed marine structures, environments with higher chloride stress, and chemical processing equipment that handles aggressive media. These bars are also used in components for desalination plants and offshore or subsea structural parts. Other suitable applications include shafts, fastener blanks, valve bodies, pump shafts, pipe connectors, welded assemblies, and other fabricated pieces. The balance of strength and corrosion resistance makes this alloy appealing for industries like oil and gas, chemical, water treatment, marine engineering, and pulp and paper.
