    Fabricating and Repairing 4130 and 4140 Steels in Heavy

    Sep 22, 2018 · In these cases, AISI/SAE 4130 and 4140 low-alloy steels are often used because their chemical composition allows them to be heat treated to high tensile strength and hardness. AISI/SAE 4130 and 4140 specifications refer to a chemical composition range only, as opposed to both a chemical composition and mechanical property ranges. High Performance Steel For Highway BridgesThe fatigue resistance of high performance steels is controlled by fatigue-prone details. Tests of welded high performance steel connections conclude that the fatigue categories given in LRFD, Section 6.6.1 also apply to high performance steels. The effective use of high performance steels can be improved by avoiding fatigue-prone details.
