Product Description
Ball Size: From 48mm to 600mm, Special size customization is available
Factory/manufacturer: Supplied from KN STEEL BALL, a professional producer in China with 20 years experiene.
Ball Material: Mainly are Stainless steel AISI316 AISI304, AISI210,
Stainless steel 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.
