When it comes to Duplex Steel Tubing, Russ Nickel Alloys typically boasts a well-balanced chemical composition, featuring around 22% chromium, 5–6% nickel, and 3% molybdenum, with added nitrogen and manganese to boost strength and corrosion resistance. This dual-phase structure provides a remarkable combination of high tensile strength (up to 620 MPa) and impressive yield strength (about 450 MPa), along with outstanding resistance to stress corrosion cracking, pitting, and crevice corrosion. These mechanical and chemical properties make duplex tubing an excellent choice for aggressive and high-pressure environments.
