Martensitic Steel
Profile
Stainless steel balls of this straight chromium steel provide maximum
hardness, toughness and dimensional stability. They are highly resistant
to rolling-contact fatigue. 440C stainless steel balls are always used
in a hardened condition, perform similarly to tool steels, and are ideal
for use in antifriction bearings (rolling bearings). After quenching, the balls
are immediately subjected to ultra-low temperatures to stabilize their
structure and further enhance hardness.
Characteristics
440C stainless steel balls achieve the highest hardness following heat
treatment: 60 HRC. The material is ferro-magnetic and makes a good
permanent magnet. Hartford 440C stainless steel balls are passivated to
remove free iron contaminants and facilitate spontaneous formation of
a protective passive film.
Corrosion Resistance
440C stainless steel balls have excellent resistance to steam, crude oil,
gasoline, blood, perspiration, alcohol, sterilizing solutions, fresh water,
and foodstuffs.
Note: we also provides stainless steel ball manufacturing using
TrimRite®, for better corrosion resistance, and we offer hollow steel ball
manufacturing as well.
Hardness
Rockwell C 58-62 measured on parallel flats.
Sizes
Available in sizes from .5mm to 63.5mm in grades 10 through 1000.
