Duplex Stainless Steel consists of about 22–25% chromium, 4–7% nickel, 3% molybdenum, and balanced levels of nitrogen and manganese, ensuring superior corrosion resistance and strength. Its two-phase microstructure of ferritic and austenitic steels gives it almost twice the strength of regular austenitic stainless steels. With its yield strength of approximately 450 MPa, tensile strength of 620–850 MPa, and elongation of up to 25%, it is best suited for applications involving high pressure. Duplex stainless steel contains better pitting, crevice corrosion, and stress corrosion cracking resistance, which makes it extremely fit to be used in aggressive industrial conditions.

Duplex Stainless Steel Air Manifolds Uses
Duplex Stainless Steel Air Manifolds have extensive application in industries that demand high mechanical strength and better corrosion resistance. They find application in oil and gas platforms, chemical plants, marine ships, and offshore platforms. The manifolds provide compressed air supply to various points efficiently without compromising pressure stability. Their superior resistance against chloride-induced corrosion makes them suitable for coastal and saltwater applications. They are also used in fire suppression systems, instrumentation equipment, and hydraulic control networks. Their long life and low maintenance requirements ensure they are a reliable choice for critical operations in harsh working environments.
