The chemical balance of 1.4420 S31655 is strictly controlled during our smelting process to ensure optimal performance. The addition of Nitrogen is key to its enhanced mechanical properties.
| Grade | C (Carbon) | Si (Silicon) | Mn (Manganese) | P (Phosphorus) | S (Sulfur) | Cr (Chromium) | Ni (Nickel) | Mo (Molybdenum) | N (Nitrogen) |
|---|---|---|---|---|---|---|---|---|---|
| 1.4420 / S31655 | ≤ 0.030% | ≤ 1.00% | ≤ 2.00% | ≤ 0.045% | ≤ 0.015% | 16.5 – 18.5% | 10.5 – 13.5% | 2.0 – 3.0% | 0.12 – 0.22% |
1.4420 S31655 exhibits higher yield strength than conventional austenitic stainless steels due to solid solution strengthening from Nitrogen. Below are typical properties at room temperature.
| Property | Value (Typical) | Unit |
|---|---|---|
| Tensile Strength (Rm) | 600 – 850 | MPa |
| Yield Strength (Rp0.2) | ≥ 290 | MPa |
| Elongation (A5) | ≥ 40 | % |
| Hardness (HB) | ≤ 215 | HB |
