2mm 8mm Precision Grade 200 Stainless Ssteel Balls of SS 420 Bearing Balls


The domestic 420 is mainly divided into two types of steel balls, 2Cr13 steel balls
(corresponding to the Japanese standard: SUS420J1 stainless steel ball), and
3Cr13 steel balls (corresponding to the Japanese standard SUS420J2 stainless steel ball).
These two steel balls have hardness, and many customers have a misunderstanding.
It is believed that the 410 stainless steel ball (corresponding to the national standard: 1Cr13 steel ball)
and the 430 stainless steel ball (1Cr17 steel ball) also have the same hardness.
Although the two steel balls are the same as the 4 series stainless steel ball,
the metallographic structure is different: one is the martensitic steel.
The other is a ferritic steel. (The information provided by the company is the original,
