Table 1 shows the percentage composition of two different steel alloys: a high-strength carbon steel and a corrosion-resistant stainless steel.
Table 1
| Element | Percentage (%) in carbon steel | Percentage (%) in stainless steel |
|---|---|---|
| Iron | 98.1 | 73.3 |
| Carbon | 1.2 | 0.2 |
| Chromium | 0.0 | 18.0 |
| Nickel | 0.0 | 8.0 |
| Manganese | 0.7 | 0.5 |
Using Table 1, state which non-metal is present in both types of steel.
