420 Stainless steel ball
Application areas:
420 stainless steel balls are commonly used in industries where high precision and rust resistance are required: motorcycle parts, pulleys, stainless steel bearings, plastic bearings, crafts, valves, and petroleum.
Material comparison:
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.

Characteristic:
The representative of martensitic steel, commonly known as stainless iron, is magnetic, has good rust resistance, and has a high hardness of HRC50-55.
