Stainless steel ball
AISI420-C
Stainless steel AISI420-C, offers higher hardness and considerable resistance to corrosion against water,steam ,oil, gaso line and alcohol.
They are not suitable to be used with chemical agents.
This type of ball is suitable for valves,special bearings,in which the protection against rustproof-greases is poor or absent .

Stainless steel ball
AISI304
The balls in AISI304 steel are suitable for applications in which resistance to corrosion plays an important role,whils hardness is a secondary factory.
This material universally considered non magnetic really has a very low magnetic per meability which however rises in connection with the work hardening for deformation.the magnetism can be reduced by a solution heat –treatment.
The balls in AISI304 steel are resistant to the corrosion of oxidative solutions,particularly to those produced by chemical components of organic nature ,the are resistant to water ,sea-air,inorganic and organic acids. However they are not very resistant to the attacks of sulphuric and hydrochloric acids.
The most common applications include aerosol pumps ,gardening and home sprays,guns,micro-pumps for perfume sprays,valves for medical equipment ,agricultural spraying pumps.

Chrome steel ball
AISI52100
Chrome steel balls are through hardened in order to achieve the maximum mechanical strength .
The balls made of this kind of material feature excellent surface finish ,considerable hardness and high load carrying capacity ,as well as excellent wear and deformation resistance .
These balls are normally used in precision ball bearings,valves and many industrial application.

Carbon steel ball
AISI1010
Balls of this type are generally used in applications where there are only moderate loads and slow rotating parts,for example castors,Conveyors and non-precision bearings,
There is a significant price saving compared to High Carbon Chrome balls
The main feature of this type of ball is the Carburised case with soft core giving resistance to shock loads ,good load carrying ability and excellent reistance to surface wear.

Hight carbon steel ball
AISI1085
Ball of this material have the advantage of being through hardened to HRC 60min and will take higher loads and provide longer life than case hardened carbon balls .
In addition are suitable for various industrial applications which do not need the use of higher cost chrome balls .
The most common applications include bicycle accessories, ball bearing for fumiture ,sliding guides ,hardware and fumiture fitting and conveyor rollers.
