Influence of Microalloying on the Strength and Corrosion of Low-Carbon Stainless Steel

Resumo

Attention focuses on how nitrogen and rare-earth metals modify the mechanical properties and corrosion characteristics of unstabilized low-carbon Fe–Cr–Ni stainless steel, additionally alloyed with silicon and molybdenum. The influence of the selected microalloying method on the mechanical properties of unstabilized low-carbon chromonickel stainless steel and its resistance to local corrosion is studied experimentally. Nitrogen-bearing 03X17H9AC2, 03X17H9AM3, and 03X18H15AM3 stainless steel microalloyed with rare-earth metals is investigated.
