Penomoran ini penting untuk mengetahui jenis dari baja yang digunakan.  Key to the AISI/SAE steel numbering system
  • Carbon Steels:
    • The first digit is "1" as in 10xx, 11xx, and 12xx
    • The second digit describes processing: "1" is resulfurized and "2" is resulfurized and rephosphorized.
  • Manganese Steel:
    • The first digit is "1" as in 13xx and is, indeed, a carbon steel. However, since manganese is a normal by-product of carbon steel making the AISI/SAE has decided not to classify it as an alloy steel.
    • The second digit is always "3"
  • Nickel Steel:
    • The first digit is "2" as in 23xx and 25xx
    • The second digit designates the percentage of nickel in the steel.
  • Nickel-Chromium Steel:
    • The first digit is "3" as in 31xx, 32xx, and 33xx,
    • The second digit designates the percentage of nickel and chromium in the steel .
  • Molybdenum Steels:
    • The first digit is "4" as in 40xx and 44xx.
    • The second digit designates the percentage of molybdenum in the steel.
  • Chromium Steel:
    • The first digit is "5" as in 51xx and 52xx
    • The second digit designates the percentage of chromium in the steel.
  • Chromium-Vanadium Steel:
    • The first digit is "6" as in 61xx
    • The second digit designates the percentage of chromium and vanadium in the steel.
  • Tungsten-Chromium Steel:
    • The first digit is "7" as in 72xx
    • The second digit designates the percentage of tungsten and chromium
  • Silicon-Manganese Steel:
    • The first digit is "9" as in 92xx
    • The second digit designates the percentage of silicon and manganese in the steel.
  • Triple Alloy Steels:
    • These steels contain three alloys
    • The first digit can be "4", "8", or "9" depending on the predominate alloy
    • The second digit designates the percentage of the reaming two alloys.
