The chemical composition of S32750 emphasizes high chromium (≈24–26%), molybdenum (≈3.0–5.0%) and nitrogen (≈0.24–0.32%) plus moderate nickel (≈6–8%) — this alloy chemistry yields a combination of very high strength and excellent localized corrosion resistance. The material’s mechanical properties in the annealed condition commonly specify a minimum ultimate tensile strength ≈ 795–800 MPa (≈116 ksi) and 0.2% offset yield strength ≈ 550 MPa (≈80 ksi), with elongation typically ≥15% depending on form and test method.
