Traditional tools are often limited in their ability to manage large datasets and the complex, non-linear relationships between alloy composition, process parameters, and mechanical properties. In contrast, machine learning models such as XGBoost, Fine-Tuned Stacking, and Ensemble methods provide a scalable solution, allowing for the simultaneous consideration of multiple mechanical property objectives. The models were trained on a comprehensive dataset of stainless steel alloys, filtering materials that meet predefined performance criteria. Among the models, the Ensemble approach achieved the best results, with a precision of 0.98 and recall of 0.93. The findings show that integrating machine learning into the alloy selection process has the potential to improve decision-making accuracy for practical engineering applications.  \n© 2025 The Authors.

Introduction  \nStainless steel alloys are widely used in industries such as aerospace, automotive, and construction, due to their superior mechanical properties, including tensile strength, corrosion resistance, and durability. In these industries, selecting the right alloy for specific applications is essential to ensure product performance and longevity. However, identifying materials that meet multiple performance objectives simultaneously, such as tensile strength, elongation, hardness, and impact resistance, presents a significant challenge for manufacturers . Traditional selection methods, which often involve trial-anderror testing and expert judgment, are time-consuming and resource-intensive, especially when multiple mechanical properties must be balanced.  \nRecent advancements in machine learni","cbCainohSVz0OK4b","https://ap.wps.com/l/cbCainohSVz0OK4b","pdf",722508,1,7,"English","en",105,"# Introduction\n## Motivation and challenges in
