To examine the effectiveness of SSTH as a viable CI for MS corrosion in 1M HCl settings, experimental and theoretical methodologies were used. According to the outcomes of WL, the IE% of 96.28 %. The results indicate that even at a lesser dosage, or 800 ppm, SSTH has good inhibitive effectiveness as an acidizing CI for MS. The inhibitive influence of SSTH is dose, time, and temperature dependent, so performance upsurges with a rising dose and lessens with a rising temperature. Additional time variation investigations revealed that the greatest inhibitory efficiency was reached after two hours of immersion. The SSTH's inhibitory activity is likely mixed-type, according to PDP data. Via the LAI model, the SSTH molecule is adsorbed. The SSTH molecules' adsorption on the MS outer-layer was corroborated by the SEM, AFM, CA, and computational approaches. All approaches reveal that SSTH can function as a CI in acidic circumstances and can thereby significantly inhibit MS corrosion.
