Stainless steel Grade 304 (SS 304) is an austenitic stainless steel that is commonly used due to its excellent resistance to corrosion, formability, and weldability. In this study, an in-depth chemical characterisation study of a 12 mm square TMT bar made of SS 304 was conducted and verified the compliance of the tested material with the IS 17875:2022. The chemical elements Carbon, Manganese, Sulphur, Phosphorus, Silicon, Nickel and Chromium levels were evaluated by following standard testing methods described in IS 228. Overall, the results revealed that the tested sample met the compositional requirements of the IS standard. Excluding carbon, tests showed that the carbon content was kept below 0.07%, while Nickel and Chromium levels remained between the optimum 8.0-10.5% and 17.5-19.5%. Metals meeting these compositions should generally retain not only corrosion resistance but are also known to rebuke disintegration and maintain structural integrity, meaning SS 304 is also differentiated for usage in multiple engineering/construction scenarios. Moreover, clearly evident from the provided low percentage of Sulphur and Phosphorus, an added benefit of ductility, possibly renouncing vulnerability to embrittlement, and decreases the chances of failure in a structural application. This study not only confirmed that the SS 304 sample adhered to a set of national standards but also confirmed that the tested material possessed the required metallurgical characteristics for reliable industrial performance. This study concluded the overall importance of standard-based testing for assuring suitability and aiding in further addressing the topic of material-based structural safety for critical infrastructure projects.
