AISI 5046
Alloy steels comprise different varieties of steels which exceed the composition limits of Mn, C, Mo, Si, Ni, Va, and B set for carbon steels. They are designated by AISI four-digit numbers. The first two digits represent the main alloying elements, and the last two digits represent the carbon content present in the alloy in hundredth of a percent. They respond more quickly to mechanical and heat treatments than the carbon steels.

| Iron, Fe | 97.775 - 98.47 |
| Manganese, Mn | 0.750 - 1.00 |
| Carbon, C | 0.430 - 0.500 |
| Chromium, Cr | 0.200 - 0.350 |
| Silicon, Si | 0.150 - 0.300 |
| Sulfur, S | ≤ 0.0400 |
