Polished 316 Stainless Steel Grinding Media Balls
316 stainless steel is one of the most commonly used stainless steel grades. 316 stainless steel grinding media balls have superior corrosion resistance and abrasion resistance, and therefore have been used in many demanding grinding and milling applications under corrosive environments. Choose between 3 mm - 25 mm in size for media.

The difference between 316 and 304 stainless steel
Similar to 304 stainless steel, Grade 316 stainless steel has high amounts of chromium and nickel. A major difference between 304 and 316 stainless steel is the the amount of molybdenum (Mo) in the chemical composition, with 316 stainless steel containing 2 to 3 percent by weight of molybdenum vs only trace amounts found in 304 stainless steel. The higher molybdenum content results in grade 316 possessing increased corrosion resistance.
Grade 316 stainless for food processing. Like many steel alloys, it has a continuous use temperature several times higher than most food making processes will ever require (more than 800 °C, or 1472 °F). 316 stainless steel is ideal for food and chemical processing because it has a high resistance to acids, alkalis, and chlorides (such as salt). Other austenitic stainless steels, such as grade 304 stainless steel, can experience severe pitting corrosion when exposed to salt, which is often present in food products.
