Understanding Chromoly Steel 4130

What is Chromoly Steel 4130?

Chromoly steel 4130, also known as Chrome-Moly or Chromoly, is a type of low-alloy steel containing chromium (Cr) and molybdenum (Mo) as its main alloying elements. The name “4130” comes from its specific alloy composition according to the SAE (Society of Automotive Engineers) designation. The steel typically consists of approximately:

• Carbono (C): 0.28 – 0.33%
• Cromo (Cr): 0.80 – 1.10%
• Molibdeno (Mo): 0.15 – 0.25%
• Manganeso (Mn): 0.40 – 0.60%
• Silicio (Si): 0.15 – 0.35%
• Sulfur (S) and Phosphorus (P): 0.035% max

This combination of elements gives chromoly steel 4130 its unique properties, making it highly suitable for applications that require a combination of strength, toughness, and resistance to wear and corrosion.
