Product Description

Stainless Steel Balls 3.175MM 1/8 Inch 440C Steel Beads G200 For Mill



Stainless steel is an alloy of steel which consists of around 89 percent steel, and 11 percent chromium.


The material was developed to handle conventional steel issues with corrosion, and


delivers much greater resistance to both rust and staining.

It is commonly used in manufacturing cutlery, can be used as a large-scale cladding for buildings,


and is often used to make medical tools, where avoiding rust and keeping implements clean is a high priority.

Hardened Stainless Steel Balls

Hardened stainless steel balls are generally made using Martensitic processes, which adds carbon to the material


and makes it tougher and harder wearing. They are also usually provided in a passivated condition,


which adds an extra micro-coating to make them even more durable.

These hardened balls tend to be used as industrial bearings, in specialist pumps, pens, cigarette lighters,


and other situations where friction is involved.

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.

Corrosion Resistance

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.


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.
