Casting Balls & Grinding Balls

Applied Area：420 stainless steel ball is used in the industries of high precision and antirust: motorcycle fittings, chain wheel, stainless steel bearings, plastic bearings, craftworks, valve, petroleum facilities 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： 316 stainless steel ball is used in many special industries, such 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：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.

Applied Area：302 stainless steel ball is widely used in automotive fittings, avigation, hardware tools, chemical industry, mostly as follows: craftworks, 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：201 stainless steel balls is widely used in all kinds of hardware industry, craftworks, 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: 201 stainless steel balls can not be used in the industry of antirust and anticorrosive. eg. in seawater or acidic substance)
