Another major advantage of this ASME SA276 duplex S32205 bar is excellent immunity to chloride SCC, plus pitting and crevice corrosion. It handles seawater, brines, and pulp chemicals better than 300 series. Here, the chromium, molybdenum and nitrogen pay off by greatly expanding the passivation layer protecting the surface. This is why duplex often replaces 316 in pipes, tanks, heat exchangers, offshore components, and anywhere seawater rapidly corrodes austenitic.

The higher alloying in S32205 does make it less weldable than primary grades yet easier to join than highly alloyed super duplexes. One needs caution with matching filler metals and controlling heat input and ferrite levels. However, the procedures are intermediate between common and highly corrosion-resistant alloys. Many fabricators readily adopt duplexes to avoid issues once they adjust parameters and qualifications.

The duplex 2205 round bar combines stainless steel’s durability and corrosion resistance with considerably higher strength than the 300 series. This enables designers to downsize parts, allowing smaller equipment and piping systems.

Architectural metals like handrails and structures also benefit from improved strength-to-weight ratios. Across industries from chemical processing to marine applications, S32205 bar is an economical upgrade substituting for 304/316 when you need better performance. It brings longer life and lower lifetime costs in harsh environments.
