Mitigation of Steel Defects: Steel defect reduction and control processes should start with stringent quality management throughout raw material identification and preparation. It is vital to ascertain the usage of high-grade raw materials that provide impurity-free substrate, particularly excess Phosphorous or Sulphur. The raw materials should undergo careful testing and assessment to detect possible pollutants that can instigate defects in subsequent manufacturing steps (Kumar & Singh, 2019). Also, correct storage and handling of materials are essential before the production phase to avoid contamination. Technological to achieve the desired temperature helps prevent issues such as inclusions, segregation or undesired phases in the steel (Lee & Kin, 2020).

To decrease steel defects, it is important to use advanced refining methodologies such as vacuum degassing and ladle metallurgy, which can eliminate dissolved gases and non-metallic inclusions. Regular sampling and chemical analyses should be performed to verify that the steel's composition meets the specified requirements in the industry. Incorporate an optimized cooling system in solidification and casting process for advanced mild steel production to avoid problems such as crack, porosity, or segregation by controlling the coolants' rates and solidification conditions (Partel & Desai, 2021). Customized mold designs, as well as routine mold maintenance, helps ensure uniform solidification that will, in turn, decrease the number of surface imperfections. Monitoring casting temperature gradients and speed is crucial to producing steel billets free from defects. In the meantime, employing specialty molds capable of producing long steel can streamline the cooling process, leading to minimized surface imperfections.

Furthermore, the adoption of non-destructive testing methods such as ultrasonic and magnetic examinations aids in the early detection of internal and surface flaws in steel and results in a more reliable final product after solidification and casting (Zhang & Chen 2018). Proper maintenance, the utilization of non-destructive testing methods, custom-mold designs, optimized cooling systems, and advanced degassing and refinement techniques are extremely essential when it comes to producing defect-free steel products. Post-processing treatments like surface cleaning, lubrication, heat treatment in glass furnace to aid in cleaning the stainless steel before being shipped to the customers.
