Physical Properties of 4130 Steel

4130 steel gets its name from specific rules outlined by the AISI and SAE. The first digit of the alloy designates the class of the steel, including its major alloying component(s). The second digit represents the relative percentage of this alloying element and/or other important secondary elements. The last two digits represent the carbon concentration in 0.01% increments. Knowing these rules, 4130 steel is, therefore, part of the 4xxx and 41xx series (the chromium-molybdenum steels) with around 1% molybdenum/chromium by mass with an included 0.30% carbon. To learn more about the differences between steels, feel free to browse our article on the types of steels.

Below is an exact chemical breakdown of 4130 steel, with tolerances:

0.28 - 0.33% Carbon

0.8 - 1.1% Chromium

0.7 - 0.9% Manganese

0.15 - 0.25% Molybdenum

≤ 0.035% Phosphorus

0.15 - 0.35% Silicon

≤ 0.04% Sulphur

4130 steel is a chromium-molybdenum alloy steel and is considered a low carbon steel. It has a density of 7.85 g/cm3 (0.284 lb/in3) and benefits from heat-treatment hardening. It is an exceptional welding steel, being weldable in all commercial methods, and is readily machined in its normalized/tempered condition. 4130 steel is easily cold worked, hot worked, and forged, but cannot be aged. It has excellent ductility when annealed and is a through-hardening alloy. 4130 steel performs best as a structural steel, and is most often found as round tube or bar stock in structural applications for aircraft and buildings.
