Product information

Grade: UNS N08926
Manufactured in: USA

UNS N08926 is a 6-moly ultra-low carbon super-austenitic corrosion-resistant steel. It has a multi-element composition of high chromium, nickel, molybdenum, nitrogen, and copper. Its PREN (pitting resistance equivalent number) is over 45, making it resistant to seawater chloride, pitting, crevice corrosion, hydrogen sulfide, and mixed media like dilute sulfuric, phosphoric, and nitric acids. Its resistance to chloride stress corrosion cracking is much better than 904L and 316L. The ultra-low carbon design ensures welds are free from intergranular corrosion, and the nitrogen content simultaneously boosts the base strength. Overall, its corrosion resistance is close to nickel-based alloys but at a lower cost. Because of this, it’s been widely used over the years in areas with severe corrosion, such as seawater desalination, FGD flue gas desulfurization, chemical acid cleaning equipment, phosphoric acid evaporators, offshore platform pipelines, pulp bleaching equipment, and chlorinated oil & gas well components.

Product parameter

Chemical Composition

Iron (Fe) is present in balance and forms the base of UNS N08926 alloy, stabilizing the austenitic structure and reducing raw material costs. 
Nickel (Ni) content is between 24.00% and 26.00%, greatly improving resistance to chloride stress corrosion cracking. 
Chromium (Cr) content is between 19.00% and 21.00%, forming a dense chromium oxide film to resist oxidizing acid corrosion. 
Molybdenum (Mo) content is between 6.00% and 7.00%, acting as a key element to strengthen pitting and crevice corrosion resistance. 
Nitrogen (N) content is between 0.15% and 0.25%, enhancing strength through solid solution strengthening and inhibiting the precipitation of brittle intermetallic phases. 
Copper (Cu) content is between 0.50% and 1.50%, synergistically with molybdenum improving corrosion resistance in reducing media like sulfuric and phosphoric acids. 
Carbon (C) content does not exceed 0.020%, ultra-low carbon prevents welding-related intergranular carbide corrosion. 
Manganese (Mn), Silicon (Si), Phosphorus (P), and Sulfur (S) are limited to 1.00%, 0.50%, 0.030%, and 0.010% respectively, strictly limiting impurities to ensure long-term corrosion stability.

Mechanical Properties

Tensile Strength: ≥650 MPa, indicating the maximum tensile force the material can withstand. 
Yield Strength: ≥295 MPa, the force at which the material begins to deform permanently. 
Elongation: ≥35%, showing the material's ability to undergo large plastic deformation before breaking; sheets bend well and pipes form easily. 
Hardness: ≤220 HB, the material’s resistance to indentation by hard objects; easy to cut in annealed state. 
Fatigue Strength: stable fatigue life under alternating seawater, sulfur-chloride, and acid-alkali corrosion environments; low risk of stress corrosion cracking. 
Elastic Modulus: 195 GPa, reflecting the material's stiffness; low deformation under medium to low temperatures, excellent dimensional stability for heat exchangers and pipelines.
