An Ultimate Guide to Duplex Steel S32205 Slip on Flange
The high yield strength of duplex 2205 stainless steel slip on flanges, which is double that of normal austenitic stainless steels like 304 and 316 stainless steel slip on flanges, distinguishes them from similar products. Due to this, Duplex Steel S32205 Slip on Flange is one of the most widely used grades of duplex for slip on flanges, being the more corrosion resistant grade of the two.
Applications vulnerable to stress-corrosion cracking, crevice corrosion, pitting, erosion, and general corrosion benefit from the higher corrosion resistance of Duplex S32205 slip on flanges. Slip on flanges are frequently used in equipment for chemical processing, petrochemicals, the power sector, and seawater because of the characteristics of duplex stainless steel.
Use of both Duplex stainless steel should be restricted to temperatures under 570° F since prolonged exposure to high temperatures can cause this material to become brittle. Duplex 32205 is one of the most popular grades of Duplex flanges. By consulting our Duplex 32205 overviews or contacting our engineering experts, you can learn more about these two grades.
Duplex Slip on Flange Grades Chemistry & Specification
The name "Duplex" comes from the mixed microstructure of the stainless steel substance known as Duplex 2205, UNS S32205, which has about equal amounts of ferrite and austenite. The most widely used type, this grade offers significant improvements over 316 stainless steel in terms of yield strength and corrosion resistance.
Duplex 2205 Technical Details: ASTM A 240, ASTM A 276 Condition A, ASTM A 276 Condition S, ASTM A 479, ASTM A 790, NACE MR0175/ISO 15156, NORSOK MDS D45 Grade F51, UNS S31803, UNS S32205, W. NR./EN 1.4462, Worst-off 1.4462 Duplex, ASME SA 182, ASME SA 240, ASME SA 479, ASME SA 789
Due to its strong resistance to corrosion in chloride-containing conditions, including saltwater, duplex steel slip on raise face flanges are perfect for use in deep-water umbilicals and a variety of other oil and gas applications. Duplex Steel Blind Raised Face Flanges have double the mechanical strength and greater corrosion resistance in most media as compared to austenitic stainless steel standard.
