Stainless Steel Ball
Manufacturing: TrimRite^®

Hartford Technologies is a leading stainless steel ball manufacturer,
offering several grades of stainless steel, as well as TrimRite stainless steel ball
production. Below is an overview of the material, its applications and its ability
to deliver cost savings or better performance versus other stainless steels.

The TrimRite® stainless steel ball is an excellent component for a wide range of instruments and other devices used in general medicine, surgery and dentistry.

The TrimRite stainless steel ball is UNS-242010. Its corrosion
resistance is superior to that of type 410, 420 and 440A stainless steel.
As autoclaving techniques have evolved, traditional 400-series alloys have
become more prone to attack, and one excellent answer has been TrimRite.
The cold formability of TrimRite makes it an ideal ball material.
It has exceptional fatigue properties, and a maximum attainable
hardness of Rockwell C 49/52.

A TrimRite stainless steel ball demonstrates good resistance to rusting
and corrosion by atmospheric conditions and various chloride-containing
environments when used in conditions below 700°F. The alloy has good
resistance to mild atmospheres, mild chemicals, most food products and
many petroleum products. Dry sand abrasive wear tests (ASTM G65,
Practice B) have shown the TrimRite stainless steel ball material to be
equivalent to Type 420 in this regard.

TrimRite stainless steel balls are an excellent replacement and improvement
for applications that use Type 420 stainless material. TrimRite provides similar
hardness and superior corrosion resistance versus Type 420 or UNS-42000.
Due to its hardness, TrimRite can also be used as a replacement for 300
series stainless steel. TrimRite can achieve ABMA Grade 16 tolerances while
300 series cannot be produced economically in large volumes better than
a ABMA Grade 40. Typical applications for TrimRite product are: poultry
watering systems, conveyor wheels, valves, medical equipment,
retail sensor tags and agricultural products.

Material Composition:

The TrimRite stainless ball is manufactured from hardenable martensitic
stainless steel and is magnetic in all conditions. Its typical analysis is:
0.22% carbon, 14.0% chromium, 0.55% nickel, 0.60% molybdenum,
0.5% manganese, 0.35% silicon, and 0.005% sulfur; the balance is iron.
