1.4125 Precision Bearing Stainless Steel Balls 11/16 Inch 27MM SUS440 440C

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.
 

440 OR 440C Stainless Steel Is 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.
