Definition of the Day:
Ferritic Stainless Steel Balls
Ferritic stainless steel balls are manufactured from the
second most common classification of stainless steel, about 25%
of total stainless production. Ferritic stainless steel balls are made from
steel with at least 12% chromium content, but no significant nickel content.
The lack of nickel means ferritic materials have lower corrosion resistance
than austenitic (chromium-nickel) stainless steels.
Ferritic stainless steel balls are magnetic.
Ferritic stainless steel balls are best suited for general and
high-temperature applications rather than service that requires high strength.
In addition to balls, ferritic stainless steel is used in automotive trim
and exhaust systems, interior architectural trim, and water tanks.
Some of the most common grades are AISI type 429
(ASTM A176, SAE 51429), also type 430 and 409.
