Stress-Strain Curves for 301 Stainless Steel (SS)

Figure 1 shows stress strain data for annealed and 1/4 hard 301 SS for a tension test [1].

Figure 2 shows several stress-strain curves for a 301 SS sheet at various temperatures. The sheet was full hard with 40% reduction [2]

Figure 2. 301 SS sheet, tensile stress-strain curves at various temperatures.


Figure 3 shows different stress-strain curves for a 301 SS sheet under tension loading at room and low temperatures. The specimen was an extra hard cold-rolled sheet with a composition of Fe-18Cr-8Ni. [3]

Figure 4 shows a 301 SS sheet with tension loading for, left) 65% cold reduction (CR), 482 C (900 F), 2 h, air cooled and right) 65% CR 399 C (750 F) 2 h, air cooled. The composition of heat : Fe-0.11C-17.25Cr-7.00Ni-0.57Mn-0.5Si. [4]

Figure 5 shows a 301 1/2-hard SS sheet for a variety of loading directions: longitudinal tensile (TL), longitudinal compressive (LC), transverse tensile (TT), and transverse compressive (TC). The composition is Fe-18Cr-8Ni. [5]

Figure 6 shows a 301 SS annealed sheet for a compressive loading at eleveated temperatures. The composition is Fe-18Cr-8Ni. [6]

Figure 7 shows the engineering stress-strain curves of UFG 301 SS with various grain sizes for tension. Huang et al used the Equal Channel Angular Pressing (ECAP) technique to vary the microstructure of 301 SS. Figure 8 shows the corresponding true stress-strain curves for this experiment along with the strain hardening rate true strain curves. [7]

Fatigue Stress-Life Curves for 301 SS

Figure 9 shows a fatigue stress-life plot for 301 SS 50% cold rolled with a mean stress of 40000 psi (276 MPa). The figure shows results for an unnotched and notched case. Both Figures 9 and 10 are for a preexposure static test.

Figure 10 shows a fatigue stress-life plot for 301 SS 50% cold rolled with a mean stress of 40000 psi (276 MPa). This S-N curve is for a fusion-weld and a spot-weld. [8]


Figure 11 shows a fatigue stress-life plot for 301 SS in full hard condition. This plot shows the knockdown in fatigue life due to fretting of 301 SS with AISI 52100 steel. [9]
