Technical Specifications
Specifications
- Carbon (C): ≤ 0.030% – limits carbide precipitation and preserves corrosion resistance.
- Silicon (Si): ≤ 0.80% – assists de‑oxidation and structural stability.
- Manganese (Mn): ≤ 1.20% – improves toughness and strength.
- Phosphorus (P): ≤ 0.035% – helps maintain cleanliness and ductility.
- Sulfur (S): ≤ 0.020% – ensures weldability and high corrosion resistance.
- Chromium (Cr): 24.0‑26.0% – provides superior corrosion resistance and strength.
- Nickel (Ni): 6.0‑8.0% – enhances toughness and stabilises microstructure.
- Molybdenum (Mo): 3.0‑5.0% – significantly boosts resistance to pitting and crevice corrosion.
- Nitrogen (N): 0.24‑0.32% – improves both strength and corrosion resistance.
- Iron (Fe): Balance – main matrix element.
