Stainless Steel Balls: AISI 316

AISI 316 stainless steel balls


316 stainless steel balls have exceptional corrosion resistance, thanks to their higher nickel and molybdenum content. Developed to resist attack by sulphuric, phosphoric and acetic acid compounds; these stainless steel balls are used extensively in applications involving photographic chemicals, inks, rayon, rubber, textile bleaches, dye stuffs and high temperature equipment. 316 stainless steel balls are also FDA approved for medical grade material.
