  • Physical Properties of 4130 SteelApplications of 4130 SteelSummary4130 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% molybdFatigue Performance of AISI 4340 Steel Ni-Cr-B-Si-Fe Comparison between the axial fatigue strength of AISI 4340 steel hard chromium electroplated and WC-17% Co HP/HVOF thermal spray coated, showed better performance for the latter. It was also observed that the shot peening process restored the fatigue life of AISI 4340
