Duplex Steel & Alloys are consistent in
manufacturing Duplex
Steel S31803 Flanges, significantly by following all
national and international standards. The material of UNS S31803 is
characterized as duplex stainless steel having a 50:50 austenite &
ferrite microstructure. The alloy blends exceptional mechanical toughness
(up to 480 MPA yield strength) and flexibility with medium to excellent
oxidation resistance in a wide range of conditions. By consent, the steel
can be furnished with a PREN (Pitting Resistance Equivalent) of >34,
offering the optimum attainable hardness and wear resist corrosion for this
metal grade.
Furthermore, the Duplex Steel S31803
Flanges are resistant to stress corrosion cracking.
The notched rigidity is excellent at both moderate & sub-zero
temperatures. These Flanges have less molybdenum and nickel than their
austenitic counterparts with equivalent resistance to corrosion.
The Chemical Composition of these Duplex Steel Flanges
• Carbon 0 to 0.03
• Chromium 21.00 to 23.00
• Manganese ≤2.00
• Silicon ≤1.00
• Phosphorous 0 to 0.03
• Sulphur 0 to 0.02
• Nickel 4.50 to 6.50
• Nitrogen 0.08 to 0.20
• Molybdenum 2.50 to 3.50
• Iron Balance

These Duplex Steel S31803
Flanges have an outstanding use in protection against corrosion;
for most situations, comparable to Stainless Steel. Superb localized weathering
resistant, including intergranular, cracking, and crevice corrosion; these flanges are
usually used at a minimum of 35 Degree C. At temps of up to 150 Degree C, the grade also
is robust to chloride stress corrosion cracking (SCC). Grade S31803 frequently performs
well in conditions that abruptly lead austenitic grades to fail. It is more resilient to
saltwater than other steel grades. Some of the common applications of these Duplex
Flanges are Chemical engineering parts, Oil & Gas sectors, manifolds, and Pumps some
of their industrial uses.
Testing and Packaging:
As a test certificate, Duplex Steel & Alloys offer the product according to various
standards. Another product examination involves a radiography test report, a raw
materials certification, and a third-party report. The products are packed according to
the materials required.
