MIM 316L
MIM 316L stainless steel (austenitic grade, food grade) is used in applications requiring extremely high corrosion resistance. Other qualities include excellent elongation and ductility, and non-magnetic properties. Parts made from this material are commonly used in the food, marine and medical industries.
MIM-316L is the most widely used MIM steel because of its high strength and corrosion resistance, making it safe for food and drinking water storage. These characteristics are very important for metals in contact with acids, which are very suitable for food-grade applications, and are mostly used in the manufacture of parts for food, drinking water, and seawater purification equipment.
