Manufacturing Process Of Duplex S32205 Flanges

Raw Material

The system controls inspect the raw material quality at the first stage in accordance with the test certificate as well as dimensions and appearance.

Material Cutting

This method of making flanges involves cutting stripes from the center plate and rolling them into a circle.


Compared to cast flanges, forged flanges typically contain less carbon and are less likely to corrode. Temperature control, weight measurement, and material grade checking are used in forgings.

Heat Treatment

The total forging cooling speed is the slowest throughout this heat treatment procedure; the standardizing and decreasing cooling speeds are faster.

Final Inspection

Measure and check the flange's dimensions and size using this procedure.

Advantages of Duplex Steel UNS S32205 Flanges

Corrosion Resistance: UNS S32205 Duplex Steel Flanges have an outstanding corrosion resistance in various environments, from chloride-rich environments such as chemical processing plants or marine platforms, through acidic environments to chloride-rich ones like those present at chemical plants or acidic environments offshore oil platforms. Their superior resistance has made these steels popular choices among professionals involved with chemical processing or offshore oil and gas platforms.

High Strength: Duplex steel UNS S32205 offers greater strength compared to austenitic stainless steels, enabling thinner sections and lighter components without compromising structural integrity - ideal in applications where weight reduction without compromise of performance is desirable.

Superior Toughness and Ductility: Duplex stainless steels exhibit good toughness and ductility at lower temperatures, making them suitable for cryogenic applications where materials must withstand extremely cold conditions without becoming brittle or becoming crackable. This feature makes them particularly suitable for cryogenic use applications where materials must endure extreme low temperature environments without becoming brittle over time.

Resistance to Stress Corrosion Cracking (SCC): UNS S32205 duplex steel has shown good stress corrosion cracking resistance when exposed to chloride-containing environments - something typically experienced with austenitic stainless steels. As such, its resilience makes this material attractive for seawater piping systems and chemical processing equipment applications.

Cost-Effectiveness: Although duplex stainless steels have higher initial costs compared to some alternative materials, their superior corrosion resistance and mechanical properties often translate to cost savings over the long-term - particularly beneficial in environments with significant maintenance/replacement expenses.

Versatility: Duplex steel UNS S32205 is an extremely flexible material suitable for applications across numerous industries, such as chemical processing, oil and gas extraction, desalination processes, pulp & paper mills and many others. Due to its corrosion-resistance strength-toughness balance it makes an appealing option for engineering projects of various sorts.
