Stainless steel ball in the process of running its purpose of heat treatment is to effectively remove the magnetic force, mainly because the ball in the process of cold heading or grinding ball will produce work magnetic, austenite to martensite slowly changing, anti-corrosion So the way of heat treatment can remove the magnetism and the correct heat treatment method. The temperature of the electric furnace is raised to 850 degrees, the stainless steel ball is usually kept for 1-2 hours and then poured into the cold water for rapid cooling, Magnets can usually be removed.

There is also a purpose of stainless steel ball heat treatment is to some extent effectively improve the hardness of their products, so that we can enhance the wear resistance of stainless steel ball, so that you can extend the life of its parts to some extent: this type of stainless steel Because the ball belongs to the high carbon and high chromium, these two elements are a pair of contradictory objects. Due to the high content of carbon and chromium, it is easy to cause the uneven distribution of chromium and thus affect the antirust property of stainless steel.

Different materials of stainless steel ball processing temperature

1.420 stainless steel ball heat treatment temperature: 2-5MM1050 degrees, 5-50MM1080 degrees and then poured into the oil, the hardness after quenching is usually HRC48-55.

2.440C stainless steel beads heat treatment temperature: 2-5MM1100 degrees, 5-50MM1150 degrees and then poured into the oil. Hardness after quenching is usually HRC57-62.

Stainless steel ball production process considerations

The quality of finished stainless steel ball and the production process to a certain extent have an irreversible connection, to a certain extent, the quality of the ball needs to be controlled, the process must be aware of the process technology needs attention.

Stainless steel ball production process requires attention to detail. The details of the process management have a very significant effect on the quality of the steel ball. Therefore, the details of the process control, the feed speed control of the abrasive fluid, and the access to the ball must all be emphasized during the production of the steel ball. The more emphasis on the details of the steel process tooling, the less likely the problem of the ball, the quality of finished steel will also be greatly improved.
