AISI 304 316 4mm 6mm 8mm 9mm Mirror-polished Drilled stainless steel ball with hole

• Applied Area:201 stainless steel ball is widely used in all kinds of hardware industry, craftwork, plastic(eg. lamps and lanterns,switch, motorcycle fittings,arks and bags,bearings and so on. )
• Speciality:It is nonmagnetic,in low price and good capability.It can be processed,jionted and drilled.The hardness is HRC≤28.(Notice: Xinxin steel ball remind you that 201 stainless steel balls can not be used in the industry of antirust and anticorrosive. eg. In seawater or acidic substance)

• Applied Area:304 stainless steel ball is the most widely used in the market, 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.

• Applied Area: 440C stainless steel ball is used in the industry of high precision and antirust: avigation ,bearings, valve, petroleum and so on.
• Capability: It is very hard to produce 440C stainless steel ball,and there are few factory can produce,so the factory who can produce 440C material go by the name of exceptive stainless steel.the heat treatment is complicated,it is easy to split,the precision must be high,it is the most rigid,min HRC 58.Its hardness is close to bearing steel ball,but it is more antirust and anticorrosive than the bearing steel ball.
• Comparison: 440C stainless steel ball is more antirust and anticorrosive than 440 stainless steel ball. The frictional resistance is enhancing while the hardness is increasing.
