Our 316 Stainless Steel Grades
- Reliable, Corrosion-Resistant, and Durable
AISI 316 Stainless Steel
Austenitic, unhardened stainless steel balls that have good resistance to corrosion from sea water, dilute nitric, acetic and sulphuric acids.
AISI 316L Stainless Steel
Good resistance to corrosion from sea water, dilute nitric, acetic and sulphuric acids. Has superior weldability over AISI 316 stainless steel
AISI 316LVM Stainless Steel
316LVM is produced using vacuum induction melting, providing exceptionally high purity, improved fatigue strength, and enhanced corrosion resistance.
AISI 316Ti Stainless Steel
316Ti is stabilised with titanium, improving resistance to intergranular corrosion at elevated temperatures.
Manufacturing & Supply
We stock and supply 316 stainless steel balls in standard and custom diameters from 0.5mm to 100mm, with various hardness levels and finishes. Balls are available heat-treated, annealed, or machined to order.

Why Choose 316 Stainless Steel Balls?
316 stainless steel balls are ideal where corrosion resistance, durability, and moderate to high precision are required. They are perfect for environments that would degrade standard carbon steel or mild steel balls, including chemical, marine, and hygienic applications.
Key Benefits
Excellent corrosion resistance, even in harsh environments
Strong and durable for load-bearing applications
Resistant to wear, abrasion, and chemical attack
Wide range of diameters, tolerances, and finishes available
UK-based supply with full traceability and quality control
Within our stainless steel offering, 316 represents a step up from standard carbon steel in corrosion resistance and chemical durability while providing a cost-effective alternative to specialty alloys.
Useful terms and definitions
Batch or Lot:
A defined quantity of balls manufactured under conditions presumed to be uniform and which is considered an entity.
Nominal Ball Diameter:
The diameter value that is used for the general identification of a ball size.
Single Ball Diameter:
The distance between two parallel planes tangential to the actual ball surface.
Diameter Tolerance per Batch:
The allowed difference between the smallest measured ball diameter and the largest ball diameter within the same batch or lot quantity.
Sphericity:
A measure of roundness expressed as the difference between the measured roundness of a ball and a theoretically perfectly round ball.
Surface Finish or Roughness:
A measure of the texture of a surface. It is quantified by the vertical deviations of the actual surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth.
