Stremgthening Characteristics of Nitrogen-Alloyed 201 Stainless Steel

- Dec 20, 2016-

Strengthening characteristics of 201 stainless steel under nitrogen enhancement from zero to approximately 1.5 wt % N concentration are improved with increasing nitrogen. Yield and tensile strength, strain hardening, and cold-work/hardness relationships are proportional to nitrogen concentration. Strengths increased with increasing nitrogen up 1.0 wt %, even though at nitrogen concentrations greater than 0.65 wt %, Cr2N precipitates formed.
