All About 4130 Steel (Properties, Strength, and Uses)


All About 4130 Steel (Properties, Strength, and Uses)

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.
