300 series stainless steel balls are also known as austenitic stainless steel balls. This series include 302 stainless steel balls, 304 stainless steel balls, 316 stainless steel balls and 316 stainless steel balls etc. The material of 300 series stainless steel balls is austenistic stainless steel, which offers prefect rust resistance, brilliant corrosion resistance, high toughness and none-magnetic (magnetism of 302 and 304 stainless steel balls could be erased. 316 & 316L stainless steel ball has no magnetism). 300 series stainless steel ball are usually used in high corrosion environment.
