Austenitic Stainless Steel Balls (Type 302-304-316)
Austenitic stainless steels offer excellent corrosion resistance in organic, acid, industrial and marine environments. The non magnetic properties combined with exceptionally high toughness at all temperatures make these steels an excellent selection with many applications. AISI 316 stainless steel offers superior corrosion resistance due to the higher nickel and molybdenum content.
