Stainless steel balls

Stainless steel balls are manufactured for applications such as bearings, bicycle parts, casters and wheels, etc. The technical innovations in a variety of industrial fields such as computers, instruments, watches, etc. have initiated the rapid growth of miniature bearings for which the corrosion resistance is required. Stainless Steel balls are in general classified into two representative groups viz., high chrome (martensitic) and high chrome-nickel (austenitic) stainless steels.
Martensitic Stainless Steel Balls
The stainless steel (>12% Cr) of this type is used with the martensitic balls when the desired corrosion resistance is rather inferior, but better mechanical properties are required as compared with the austenitic stainless steel. This feature makes them especially useful for ball bearings and valve applications.
Type: 440 C
Feature: 18 Cr - Mo-1.0C
Hardness Quenched & Tempered HRC: RC 58 - 65
Tensile Strength: 75 kgf/mm²
Specific Weight: 7.75 gf/cm³
Austenitic Stainless Steel Balls
The non-magnetic high chrome-nickel stainless steel with the austenite structure shows no quench harden ability. However, it is featured with high toughness, good corrosion resistance, and remarkable mechanical properties at high and low temperature. The balls made of them are widely used for valves and the related equipments.
