Corrosion is a global menace which has imparted the world economy greatly. One of the solutions proffered to these challenges is the use of inhibitors. Several natural inhibitors have been used to protect engineering materials from corroding. This research is focused on investigating the inhibitive properties of Hura crepitans seed (HCS) on Duplex Stainless Steel 2101 (DSS2101) in H2SO4. The selected plant part was subjected to characterization to determine the presence of organic anti-corrosion agents present. From the result, phytochemicals such as saponin, tannins, steroid and flavonoids were observed. The presence of the organic group accounted for the inhibitive efficiency recorded in the environment. The polarization studies revealed that generally the inhibitor produced from seed extract of Hura crepitans, improved the corrosion resistance of DSS2101 in 0.5M H2SO4. The optimum corrosion inhibitor efficiency was observed at 0.2% inhibitors in 0.5M H2SO4 for 2101DSS.
