Chromoly is an abbreviation for "chromium-molybdenum steel". Alloy steels are broken down into two groups: low alloy steels and high alloy steels.
These steels have greater strength, hardness, hot hardness, wear resistance, hardenability, or toughness compared to carbon steel. However, they may require heat treatment to achieve such properties. Common alloying elements are molybdenum, manganese, nickel, chromium, vanadium, silicon and boron.
