What Is Duplex Stainless Steel Flange ?

ASTM S31803 Duplex Slip On Flanges can be used in the aerospace industry, heat exchangers and oil refineries. Duplex UNS F32205 Orifice flange are produced to ATSM A182 or ASME SA182 standards. Duplex Steel RTJ Flange is also tough at low temperatures. ANSI S31803 Duplex Steel Blind flanges are not suitable for use above 300°C as they may precipitate brittle micronutrients.

Is duplex stainless steel better than stainless steel?

Determining between duplex stainless steel and traditional stainless steel depends entirely upon your project requirements. Duplex stainless steel, known for its two-phase structure, excels in environments demanding corrosion resistance and robust strength simultaneously – such as oil and gas industries. Although alloy-rich products come at a higher cost, their investment proves worthwhile in harsh corrosive environments. However, traditional stainless steel grades 304 and 316 offer strong corrosion resistance at a more reasonable cost, making it suitable for widespread applications like construction and food processing. Your decision on the material depends upon a range of considerations such as corrosion resilience, strength requirements and budget limitations to ensure it perfectly aligns with your unique project needs.

What is the difference between duplex SS and SS 316?

Duplex stainless steel and SS 316 differ primarily in their microstructures and performance characteristics. Duplex features a dual-phase microstructure consisting of austenitic and ferritic phases that work in harmony for an excellent combination of corrosion resistance and strength, whereas austenitic stainless steels such as SS 316 feature single phase austenitic microstructures offering great corrosion resistance yet lower strength compared to duplex. When selecting either option depending on a given application’s specific requirements; generally duplex stainless steel is preferred where higher strength-to-corrosion resistance ratios are desired.
