Stainless Steel Ball

We offers a wide range of stainless steel materials such as 302, 304, 316, 316L, 420, 440. All of our stainless steel balls are passivated. Other stainless steel materials are available upon request.

AISI 304

Feature: austentitic, corrosion resistance, slightly magnetic, however annealing canmakes it non-magnetic

General Applications: Used in valves and relevant application, food products, aerosols, home sprays, perfumes and medical equipments.

AISI 316

Feature: non-magnetic, good corrosion resistance even when exposed to marine atmosphere and sulfuric acid.

General Applications: used in presence of sulphuric, phosphoric and acetic acides, Mainly used in chemical, paper and textile industries.

AISI 316L

Feature: Characteristics same as 316 but with excellent corrosion resistance. Lower carbon content than regular 316.

General Applications: Expecially used in Jewelry, and Human Implant Applications

 

AISI 420

Feature: Magnetic, harden-able, fair corrosion resistance

General Applications: Used for special bearings and valves where balls requiring a combination of hardness and corrosion resistance

AISI 440C

Feature: Magnetic, highest hardness, good corrosion resistance.

General Applications: Used in bearing, nozzles and valves where lubrication is poor or absent.

Ball Production Process

Raw material, wire drawing:The wire rod is drawn to the required size, in closer tolerance so that it can be used in cold forging.

Cold forging:Calculated length of wire is sheared and cold forged in a close die to give it the spherical shape.

Flashing: The rolling between plates with concentric grooves in order to eliminate the heading witness marks and in increase the precision of the ball, in this operation the spheres are ground between two concentric pressure plates to correct the spherical shape and remove the seam formed in the cold forging.

Heat treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.

Descaling: This step removes the residues and by-products on the preceding process.

Hard Grinding: Here the hardened balls are ground to improve surface finish and geometrical parameters. Several careful grinding processes with ceramic wheels lead to a higher size precision preparing the balls for the next final lapping operation.

 

Finishing: Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish, increasing wear resistance and product longevity.

 

Inspecting: All products pass through proprietary, automated inspection process.
