China alibaba Outdoor gardern 36'' hollow steel ball

Material	Applied Area	Speciality	physical capability
AISI 420	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.	It is also called stainless iron,it is magnetic and has good antirust capability.The HRC is 50-55.	Tensile strength:280,000 psi
			Yield strength:270,000 psi
			Modulus of Elasticity:29,000,000 psi
			Density:0.275 lbs/cubic inch
AISI 440C	440C stainless steel ball is used in the industry of high precision and antirust: avigation ,bearings, valve, petroleum and so on.	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.	Tensile strength:285,000 psi
			Yield strength:275,000 psi
			Modulus of Elasticity:29,000,000 psi
			Density:0.277 lbs/cubic inch

AISI 304	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.	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.	Tensile strength:100,000 to 180,000 psi
			Yield strength:50,000 to 150,000 ps
			Tensibility:55 to 60%
			Modulus of Elasticity:29,000,000 psi
			Density:.286 lbs/cubic inch
AISI 316	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.	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.	Tensile strength:90,000 psi
			Yield strength:45,000 psi
			Tensibility:35%
			Modulus of Elasticity:28,000,000 psi
			Density:.290 lbs/cubic inch
AISI 302	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.	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.	Tensile strength:100,000 to 180,000 psi
			Yield strength:50,000 to 150,000 psi
			Tensibility:55 to 60%
			Modulus of Elasticity:29,000,000 psi
			Density:.286 lbs/cubic inch
AISI201	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. )	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)	Tensile strength:100,000 to 180,000 psi
			Yield strength:50,000 to 150,000 psi
			Tensibility:55 to 60%
			Modulus of Elasticity:29,000,000 psi
