304 Stainless Steel Grinding Media Balls, 1 kg

  • $ 19900


Polished 304 Stainless Steel Grinding Media Balls

304 stainless steel is the most common type of stainless steel. 304 stainless steel grinding media balls have excellent corrosion resistance and abrasion resistance, and therefore have been widely used in many different grinding and milling applications. Choose between 1 mm - 50 mm in size for the stainless steel 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.
