Selection These materials are suitable for balls

As already described above, balls can be made from all three main groups of materials. There are hardly any limits to the choice of suitable material. The following are examples of materials that are very popular in the manufacture of balls:

1.4301 stainless steel / AISI 304

1.4301 is the first commercially available stainless steel and is the most widely used stainless steel in the world. Due to its good mechanical properties and corrosion resistance, the material 1.4031 is also often used in spherical form.

1.4306 stainless steel / AISI 304L

The material 1.4306 is similar to the material 1.4301. Both are stainless steels, the notable difference is the carbon content. Due to the lower carbon content of 1.4306, the material is of higher quality than 1.4301. The carbon content affects the corrosion resistance at temperatures between 400 and 850 degrees Celsius. These temperatures arise, for example, during welding. Thanks to the stud welding technology, stainless steel balls can also be welded quickly and safely. Ball welding is ideal for use in decorative metal design, e.g. in the furniture industry.

1.4034 stainless steel / AISI 420c

The best corrosion resistance with the material 1.4034 is achieved in the quenched and tempered condition with a polished surface. A special feature of the material, however, is the high hardness assumption. As a result, 1.4034 is very often used for rolling bearings. Balls made of 1.4034 are particularly suitable for ball valves.

1.4404 stainless steel / AISI 316L

The material 1.4404 is often used in the manufacture of balls. It is one of the corrosion-resistant types of stainless steel and is characterized by its high resistance to non-oxidizing acids. Balls made of the material 1.4404 are used at temperatures of up to 550 degrees Celsius and are used in various fields of application, such as in the food and cosmetics industries.

1.0616 steel / C85

The hardened carbon steel 1.0616 has a high load-bearing capacity and resilience and is conductive. However, the disadvantage of the material is that it is not corrosion-resistant. Therefore it can only be used in certain areas of application. Balls made from the material 1.0616 are used in ball bearings for furniture, furniture casters and rollers for conveyor systems.

1.3505 roller bearing steel

1.3505 is a standard rolling bearing steel from which balls are made. Balls made from this material are hardened, conductive and magnetic. In addition, the material 1.3505 has good to very good physical properties, but is only corrosion-resistant to a limited extent. Balls made of roller bearing steel are particularly popular in ball bearings, in general mechanical engineering, as well as in aviation and many other areas.

Silicon nitride Si3N4

Ceramic balls are characterized by their extreme hardness and resistance. In the ceramic sector, silicon nitride balls are one of the most widely used balls. Due to the high precision of Si3N4 balls, they are used in high-precision bearings. The accuracy of the balls is therefore also used in the medicine and aerospace industries.
