Heat treating and metal finishing are distinct but related processes in manufacturing. Heat treating involves altering the internal structure of metals through controlled heating and cooling to improve strength, hardness, or ductility. Metal finishing focuses on surface treatments like polishing, coating, or plating to enhance appearance and corrosion resistance. Both roles require specialized skills and certifications, but they serve different purposes in the production process.
