201: Cr-Mn stainless steel balls, with properties similar to AISI 302/304 balls (slightly higher mechanical characteristics). Balls are provided in the passivated condition.
304: Unhardened austenitc stainless steel balls, they display good mechanical characteristics, toughness and corrosion resistance. AISI 304L provides lower carbon content, AISI 302 better mechanical characteristics. Balls are provided in the passivated condition.
316: Austenitic stainless steel balls with higher corrosion resistance than AISI 304 balls. They show good toughness. AISI 316L has a lower carbon content (maximum 0,030%). Balls are provided in the passivated condition.
420C: Martensitic hardened stainless steel balls, they feature good hardness, corrosion resistance, wear and abrasion resistance. Balls are provided in the passivated condition.
440C: Martensitic hardened stainless steel balls, they feature remarkable hardness, wear resistance, surface finishing, narrow dimensional tolerances. For that reason this type of steel is frequently used in precision devices. Balls are provided in the passivated condition.
201: Similar to the corrosion resistance of AISI 302/304 materials.
304: Very good corrosion resistance with respect to organic substances, oxidating solutions, foodstuff, sterilizing solutions. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of hot chloride solutions and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 shows slightly best corrosion resistance with respect to AISI 304/304L stainless steels.
316: Very good corrosion resistance with respect to organic substances, good resistance to several strong acids (acetic, phosphoric, sulphuric acid) and on sea water. They are subjected to pitting and crevice corrosion in presence of hot chloride solutions and to stress corrosion when temperature exceeds 60°C. They do not resist in contact with hydrochloric and hydrofluoric acids, aqua regia, iron and magnesium chlorides.
420C: Good corrosion resistance in industrial atmosphere, freshwater, steam, alcool, ammonium, several oilfield products and organic compounds, dairy products, mild acid environments. Fairish in foodstuff and alkaline solutions. Fair in salt atmosphere. It does not resist in contact with sea water and strong acids (even if diluted).
440C: The material resists to corrosion in contact with freshwater, steam, oil, petrol, alcohol. They are subjected to pitting corrosion in sea water environments. Poor corrosion resistance in acid environments.
201: Special bearings, automotive components, switches, die casting devices. They are widely used in the electronic industry.
304: Special bearings and pumps, aerosol pumps, gardening and household sprayers, perfume miniature pumps, seams, medical application valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and military industry.
316: Special bearings, pumps and valves, aerosol and dispenser sprayers. Utilised in the foodstuff, paper, chemical, rubber, military, textile industry. Applications in photographic devices, medical instruments, quick couplings, recirculating balls, ink cartridges, jewels.
420C: Special bearings, anti-friction bearings, special pumps, recirculating balls, lighters, pens, automotive seatbelts & components.
440C: Precision bearings, anti-friction bearings, special valves, conveyor belts and rollers, ballpoint pens. They are used in foodstuff, medical instruments, quick couplings, recirculating ball bearings, knotting devices, oil refinery devices.
Because we're not just a ball company, we can go beyond this technology to provide subassemblies or complete solutions. We can combine our ball technology with our injection molding, segmented linear bearing, and motion control expertise. We have extensive in-house tool room capabilities and offer rapid prototyping. With manufacturing facilities that span the globe, we can produce and deliver your solution with minimum time and cost.
Distinctively Shaped Ball: We offer a variety of flat, diagonally cut, cone and pin shaped balls that are typically used as hardened polishing and shaping tools. For example, the diagonally cut and shaped balls can be used to polish surfaces with sharp angles. Flat balls are typically used to polish uniformly shaped surfaces such as soins. Sizes and materials can be made available to suit your needs. Contact us to find the product that's just right for you.
Drilled Ball: Decok offers a full range of sizes, hole depths (including thru-hole), diameters and materials. Typical applications include body jewelry, earring posts, rings, seal slides, valves, and automotive engine push rods.
Plated Ball: Platings are used to enhance the physical properties of precision balls. These may include added hardness (titanium nitride), corrosion resistance (molybdenum disulfide), noise supression (rubber), and electrical characteristics (gold). Decok offers a myriad of plating to meet your needs.
Hollow Ball: Hollow balls are typically used for weight sensitive applications such as aircraft ball transfer units, liquid float systems, and custom ball valves. We provide 201, 304, 316 stainless steel hollow balls in a variety of sizes.

Heading: A coil of wire is cut to the required length and each piece compressed and shaped into balls using a pressing machine.
Flashing: The surface of the balls is ground to remove the bands generated in the heading process.
Heat Treatment: After the bands have been removed, the balls are quenched adn tempered to give them sufficient strength and durability.
Grinding: In addition to removing parts decarburized in the heat treatment, this process adjusts dimensional precision and finishes the balls to the stipulated dimensional difference.
First Lapping: The dimensional precision of the balls is further improved and they are finished to the specified dimensional difference.
Second Lapping: In addition to increasing the balls' dimensional precision to grade level, this process gives the surface of the balls a smooth, glass like finish.
Visual Inspection: All of the finished steel balls and all of their surface visually inspected automatically. These visual inspection ensure that the balls supplied to customers have no flaws.
Packaging: Balls that pass visual inspection are treated with anti-corrosive oil and then packed in paperboard boxes.
After precision washing, oiling & before packing sample balls from the batch are sent for final audit to check for surface roughness, roundness, waviness, lot size variation and hardness in a sophisticated laboratory, according to specified control plans and dock audit procedures. Once all requirements are met, a test certificate is then prepared for the customer. Our sophisticated laboratory is equipped with high precision, worldwide respected machines and equipment and is managed by properly trained and qualified personnel.
