Results of the Monotonic Tensile Loading Test

Figure 4 shows the stress-strain diagrams of the No. 3 stainless steel samples together with an optimized carbon “Tempcore” bar.

Experimental results concerning four major quantities, like yield stress-ultimate stress, ultimate over yield ratio, uniform elongation at maximum force are given in Table 1, in comparison with a 450 MPa carbon “Tempcore” steel rebar. It is evident that the AISI304 rebar is much superior with respect the carbon steel, even if this last is of the class 500 MPa instead of 450 MPa.
