Technical Specifications
Chemical Composition
- Carbon (C): ≤ 0.03% – Controls carbide formation and maintains toughness.
- Silicon (Si): ≤ 1.00% – Supports de‑oxidation and strength.
- Manganese (Mn): ≤ 2.00% – Helps toughness and structural integrity.
- Phosphorus (P): ≤ 0.030% – Limits brittleness.
- Sulfur (S): ≤ 0.020% – Ensures weldability and toughness.
- Chromium (Cr): 21.0–23.0% – Provides corrosion resistance & strength.
- Molybdenum (Mo): 2.50–3.50% – Improves pitting & crevice corrosion resistance.
