304 Stainless Steel Balls

Applied Area：304 stainless steel ball is the most widely used in the markets, it can be used in iatrical instrument, chemical industry, avigation, plastic hardware: scent bottle, sprayer, valve, nail polish, switch, washing machine, fridge, air condition, medicinal materials,automotive fittings, bearing, nursing bottle and so on.
Speciality：A representative of Austenitic stainless steel.it is nonmagnetic,but magnetic after rolling, and the magnetism can be taken out, HRC≤26. It has good antirust and anticorrosive capability.
Comparison：304HC stainless steel ball is softer and can be pocessed more easily than 304 stainless steel ball, while 304L stainless steel ball has stronger antirust and anticorrosive capability than the above two, It can be jointed easily.
