Stainless Steel 202 Low-Nickel High-Manganese Chemical Analysis (% by Weight)
| Element | Chemical Symbol | Minimum (%) | Maximum (%) | Specification Role |
|---|---|---|---|---|
| Carbon | C | — | 0.15% | Controls base tensile strength & core hardness |
| Manganese | Mn | 7.50% | 10.00% | Combines with sulfur, increases hardenability and hot workability |
| Chromium | Cr | 17.00% | 19.00% | Forms passive chromium oxide layer for oxidation & corrosion resistance |
| Nickel | Ni | 4.00% | 6.00% | Improves notch toughness, cryogenic ductility & hardenability |
| Nitrogen | N | — | 0.25% | Austenite stabilizer; increases yield strength and PREN pitting number |
| Silicon | Si | — | 1.00% | Deoxidizer during melting; improves high-temperature scaling resistance |
* Ladle chemical analysis verified using optical emission spectrometer (OES) calibrated to NIST certified reference materials. Full chemical results recorded on EN 10204 3.1 MTC.
