Fatigue Behavior of Spot Welded High-Strength Sheet

The spot weld fatigue properties of advanced automotive high-strength sheet steels were evaluated and compared to conventional sheet steels BY R. W. RATHBUN, D. K. MATLOCK, AND J. G. SPEER ABSTRACT. The fatigue behavior of spot welds was examined in three high-strength steels -- HSLA 50, dual-phase 590, andFerritic-Bainitic (FB) Steel - WorldAutoSteelCompared to HSLA steels with the same level of strength, FB steels also have a higher strain hardening exponent (n-value) and increased total elongation. Engineering and true stress-strain curves for FB steel grades are located in Figure 2-15 of the Advanced High-Strength Steel Guide to Repairing and Welding High Strength Steel The benefit of high strength steel is that it can replace standard steel of greater thickness. The common tensile strength of steel you may find in the average automotive body includes 270 MPa, 440 MPa, 590 MPa, 980 MPa and 1,500 MPa. The higher the number the stronger or harder the steel. The most common use for 1,500 MPa Steel is door pillars.
