Labh Steel is one of the leading producers and suppliers of F51 Duplex Stainless Steel coils and strips. F51 Duplex Stainless Steel is a two-phase, ferritic-austenitic alloy containing 22% chromium, 3% molybdenum, and 5–6% nickel. Known for its excellent mechanical strength and high yield strength—double that of standard austenitic stainless steel grades—it also offers outstanding resistance to stress-corrosion cracking, crevice corrosion, pitting, erosion, and general corrosion, making it ideal for harsh environments.
F51 Duplex Stainless Steel Coils & Strips (UNS S31803 / UNS S32205) are widely used in industries such as chemical processing, transportation, and storage; marine and land freight tanks; biofuel production; food processing; pulp and paper manufacturing; oil and gas exploration and processing; waste management; and high chloride environments. A significant advantage of F51 Duplex Stainless Steel is its cost-effectiveness—its enhanced yield strength often allows for reduced material thickness, making it more economical than comparable austenitic stainless steel grades.
