Stainless-steel Spheres– Precision Dimensions from 7.5 mm to 250mm
Product Grades
We offer stainless steel balls in multiple top quality grades: AISI 304, 304L, 316, 316L, 420, 420C, 440, and 440C. Each grade meets stringent global requirements for composition and efficiency. AISI 304 and 304L offer superb deterioration resistance and are suitable for food, medical, and general commercial use. AISI 316 and 316L deal even better resistance to chlorides and acids, making them appropriate for marine and chemical atmospheres. The 400-series grades– 420, 420C, 440, and 440C– are harder and more wear-resistant. They function well in applications that require high stamina and resilience, such as shutoffs, pumps, and bearings.
Dimension Variety and Tolerance
Our stainless-steel balls are offered in diameters from 7.5 mm up to 250mm. We generate them with tight dimensional tolerances to meet accuracy demands. Criterion tolerance classes consist of G10, G20, G50, and G100, however customized grades are also feasible upon demand. Every batch undergoes extensive assessment to make sure consistent satiation, surface area finish, and dimension accuracy.
Surface Area Complete and Solidity
Surface area coatings vary from conventional polished to mirror-like lapped surfaces, depending upon the application. Hardness varies by product: 300-series spheres are commonly softer (around 150– 200 HV), while 400-series balls can reach up to 58– 60 HRC after warmth treatment. This makes them appropriate for durable mechanical tasks where impact and abrasion resistance issue.
Common Applications
These spheres are utilized throughout lots of markets. You’ll locate them in ball shutoffs, circulation meters, bearings, inspect valves, vehicle parts, food processing tools, and aquatic hardware. Their integrity, cleanability, and long service life make them a relied on selection wherever performance and health are crucial.

Versatile Dimensions for Diverse Requirements
Stainless steel spheres from 7.5 mm to 250mm in diameter offer several markets. Their dimension variety allows usage in both little mechanisms and huge commercial systems.
Typical Qualities and Their Strengths
We provide balls made from AISI 304, 304L, 316, 316L, 420, 420C, 440, and 440C stainless steel. Each quality has special homes. 304 and 304L resist rust well and work in food processing or medical tools. 316 and 316L manage harsher environments like marine or chemical setups. 420, 420C, 440, and 440C are harder grades. They match applications needing high wear resistance and strength, such as shutoffs, pumps, or cutting devices.
Where These Spheres Are Used
You’ll find these steel rounds in bearings, valves, hinges, and examine shutoffs . They likewise show up in food machinery, pharmaceutical mixers, and cosmetic tools due to the fact that they satisfy health criteria. In the aerospace and protection markets , larger spheres (over 100mm) assistance in actuators and control systems. The automobile sector utilizes them in fuel systems and suspension components. Marine hardware relies on 316-grade rounds for saltwater resistance. Industrial pumps and compressors usually make use of 440C balls due to their solidity and resilience.
Why Material Selection Issues
Picking the appropriate stainless-steel quality ensures lengthy life and trusted efficiency. A round utilized in a salted environment needs better corrosion resistance than one in a completely dry setup. A component under heavy load requires higher hardness. Matching the ball’s material to its task protects against early failure and lowers maintenance prices. All our balls are precision-ground to tight resistances, so they roll smoothly and fit precisely where required.

5 FAQs of 7.5mm-250mm Stainless Steel Balls Metal Ball AISI304, 304L, 316, 316L AISI420, 420C, 440, 440C
Frequently Asked Questions About Stainless Steel Balls
What sizes are available for these stainless steel balls?
We offer stainless steel balls in diameters from 7.5mm up to 250mm. This wide range suits many different uses, from small precision parts to large industrial components.
Which grades of stainless steel do you supply?
Our balls come in several common grades: AISI 304, 304L, 316, 316L, 420, 420C, 440, and 440C. Each grade has its own strength, hardness, and corrosion resistance. Choose based on your specific needs.
Are these balls suitable for high-corrosion environments?
Yes, especially grades like 316 and 316L. They contain molybdenum, which gives them better resistance to saltwater and harsh chemicals. For less demanding conditions, 304 or 304L may work well.
Can I use these balls in high-wear applications?
Absolutely. Grades such as 440C and 420C are heat-treatable and very hard. They handle heavy loads and constant friction better than standard austenitic grades like 304.
How precise are the dimensions and surface finish?
Our balls meet strict industry standards for roundness, diameter tolerance, and surface smoothness. Precision grades are available for applications that need tight tolerances, like bearings or valves. Standard grades work fine for general use.
