1.4882 Chemical Composition – EN 10090:1998
| Carbon (C) | Silicon (Si) | Manganese (Mn) | Nickel (Ni) | Phosphorus (P) |
|---|---|---|---|---|
| 0.45 – 0.55 | max 0.45 | 8 – 10 | 3.5 – 5.5 | max 0.045 |
| Sulfur (S) | Chromium (Cr) | Tungsten (W) | Niobium (Nb+Ta) |
|---|---|---|---|
| max 0.03 | 20 – 22 | 0.8 – 1.5 | 1.8 ≤ Nb+Ta ≤ 2.5 |
Enhanced Composition: High chromium content (20-22%) ensures excellent oxidation resistance, while niobium (1.8-2.5%) provides exceptional high-temperature strength and creep resistance for demanding valve applications.
1.4882 Mechanical Properties (Heat Treated Conditions)
| Property | Value | Unit | Condition |
|---|---|---|---|
| Tensile Strength (Rm) | 950-1150 | MPa | +AT |
| 0.2% Proof Strength (Rp0.2) | 580 | MPa | +AT |
| Min. Elongation at Fracture (A) | 12 | % | +AT |
| Reduction in Cross Section (Z) | 15 | % | +AT |
| Rockwell C Hardness (HRC) | 30 | HRC | +AT |
Heat Treatment Code: +AT = Annealed
Performance Advantage: Superior tensile strength of 950-1150 MPa combined with excellent ductility makes 1.4882 ideal for high-stress valve applications in internal combustion engines.
