ASTM A815 / ASTM A790 UNS S31803 Duplex Steel Seamless Pipes & Tubes, Welded Pipes & Tubes & ERW Pipes Supplier in India
Amardeep Steel is a pioneer manufacturer and supplier of high-quality Duplex Steel UNS S31803 Pipes and Tubes, in India. We have ASTM A790 UNS S31803 pipes, A790 S31803 pipes, and Duplex S31803 seamless pipes, produced to the global quality requirements.
These Duplex Steel S31803 pipes are highly corrosive, have great tensile strength and are very durable. Duplex S31803 seamless pipe products boast of excellent resistance to stress corrosion cracking, pitting and crevice corrosion and thus are suitable in the demanding industrial applications.
ASTM A790 UNS S31803 pipes are based on both austenitic and ferritic stainless steel, but have greater strength and resistance than the standard grades of stainless steel. Our Duplex Steel UNS S31803 Pipes and Tubes will be offered in seamless, welded and ERW, in various sizes and specifications.
Duplex Steel UNS S31803 tubes find wide application in oil and gas industries, marine industries, petrochemical industries and chemical processing industries because they are highly mechanically strong and have high resistance to corrosion.
S31803 Duplex Tubes have a two-phase microstructure that includes ferrite and austenite, increasing the strength and durability. These A790 S31803 pipes and tubes are magnetic and provide enhanced resistance to chloride stress corrosion cracking.

FAQs – Duplex Steel UNS S31803 Pipes & Tubes
What is the difference between S31803 and S32205?
S32205 is an enhanced version of S31803 with tighter composition control, particularly higher nitrogen content, which improves corrosion resistance and mechanical strength. Both grades are commonly grouped as Duplex 2205.
Where are Duplex S31803 pipes used?
Duplex Steel S31803 pipes are widely used in oil & gas, marine engineering, chemical processing, pulp & paper, desalination plants, and heat exchanger applications due to their strength and corrosion resistance.
Are ASTM A790 UNS S31803 pipes corrosion resistant?
Yes, ASTM A790 UNS S31803 pipes provide excellent resistance to pitting, crevice corrosion, chloride stress corrosion cracking, and general corrosion in aggressive environments.
What standards apply to Duplex Steel UNS S31803 Pipes & Tubes?
The primary standards for Duplex Steel UNS S31803 pipes and tubes are ASTM A790 and ASME SA790, covering seamless and welded ferritic/austenitic stainless steel pipes for corrosive service.
