Investigation of Possibility for Reducing AISI 303 Stainless Steel Pitting Corrosion by Microalloying with Boron or Zirconium

Abstract

This research examined the possibility of reducing the effect of sulfur content on the corrosion behavior of AISI 303 by microalloying with boron or zirconium. Results demonstrated that microalloying significantly reduced pitting corrosion intensity, particularly in lower chloride concentrations, bringing AISI 303 performance closer to 304 stainless steel standards.
