Abstract :The performance of Butan-1-ol insert ignore into journalissuearticles values(BTU); on the pitting corrosion inhibition of austenitic stainless steel insert ignore into journalissuearticles values(Type 304); in dilute sulphuric acid contaminated with recrystallized sodium chloride was investigated with the aid of potentiodynamic polarization technique. Corrosion potential, pitting potential, passivation potential, nucleation resistance, passivation range, passivation capacity measurements and potentiodynamic analysis were used to assess the pitting resistance characteristics of the stainless steel. Results showed that pitting potential increased progressively with proportionate increase in BTU concentration. This occurred with corresponding increase in the passivation range which shows an enhanced resistance to pitting corrosion.
