Low-alloy steels with molybdenum (0.15–0.25%) and chromium (0.8–1.1%) added as strengthening agents are known as alloy steel AISI 4130 bars. Iron as the base element, silicon (0.15–0.35%), manganese (0.40–0.60%), and carbon (0.28–0.33%) make up the usual composition. These bars have outstanding mechanical qualities, such as good ductility, a yield strength of about 460 MPa, and a tensile strength of 560–670 MPa. They are appropriate for heavy-duty applications due to their durability and resistance to impact. In addition to their high fatigue strength, AISI 4130 bars can be heat-treated to further improve mechanical performance.
