5. Conclusion 1) By comparing the uniaxial tensile test with the numerical simulation results, the mechanical properties of 316L austenitic stainless steel under different cold working rates can be obtained. 2) The linear elastic-hardening model can better reflect the mechanical behavior of 316L austenitic stainless steel after cold working. 3) As the amount of cold work increases, the yield stress of 316L austenitic stainless steel increases greatly, and the reduction factor decreases.
