201 304 316 420 440 Stainless Steel Balls

201 Stainless Steel Balls

• 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：302 stainless steel ball is widely used in automotive fittings, avigation,harware tools, chemical industry. mostly as follows: craftwork,bearings, chain wheel, iatrical instrument and so on.
• Speciality：302 stainless steel ball is close to 304 stainless steel ball,but its hardness is higher than 304, HRC≤28. It has good antirust and anticorrosive capability.

• 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： 316 stainless steel ball is used in many special industry as iatrical instrument,chemical industry, avigation, scent bottle, sprayer, valve, nail polish,mobile phone fittings.
• Speciality： Austenitic stainless steels,It is the best steel ball in the steel ball area,HRC≤26,its Capability is better than 304 stainless steel ball.
• Comparison： 316L stainless steel ball is more soft and shining than 316 stainless steel ball and can be used in persons’ decoration.

• Applied Area：420 stainless steel ball is used in the industry of high precision and antirust: motorcycle fittings, chain wheel,stainless steel bearings, plastic bearings, craftwork, valve, petroleum and so on.
• Speciality：It is also called stainless iron,it is magnetic and has good antirust capability.The HRC is 50-55.

• 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, 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.
