Not all stainless steel grades are the same. In this short video, you’ll learn the basics of stainless steel grades like 304, 316, ferritic, and martensitic. Understand why some stainless steels are non-magnetic, why others attract magnets, and how chromium protects steel from corrosion. From kitchen utensils and appliances to chemical pipelines and cutting tools, each grade has a specific purpose. This quick explanation will help students, engineers, and professionals choose the right stainless
