Jinay Metals, a top-notch manufacturer and supplier located in Dubai, UAE, specializes in high-quality Duplex Steel S31803 Pipe Fittings that are known for their outstanding strength, durability, and resistance to corrosion. These fittings are designed to excel in tough environments, blending the best features of both austenitic and ferritic stainless steels. With a commitment to precision manufacturing, rigorous quality control, and compliance with international standards, Jinay Metals delivers products that promise longevity and reliability. Duplex Steel S31803 Pipe Fittings are perfect for sectors like oil and gas, petrochemical, marine, and power generation, where strength and resistance to corrosion are essential.
These fittings are made up of about 22% chromium, 5–6% nickel, and 3% molybdenum, with added nitrogen to boost their strength and corrosion resistance. This well-balanced composition results in a dual-phase microstructure of ferrite and austenite, giving them twice the yield strength compared to standard austenitic stainless steels. The alloy is highly resistant to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. Plus, it maintains good weldability, toughness, and stability even under high-pressure and high-temperature conditions.
