Stainless steel balls are resistance to corrosion and staining, low maintenance and familiar lustre.
a) Features of 201 stainless steel ball:
1. Austenitic steel, essentially nonmagnetic in the annealed condition and becomes magnetic when cold worked, with a lower price to substituted for AISI 301 in many applications.
2. Hardness HRC22-28
b) Features of 304 stainless steel ball:
1. Austenitic steel, magnetic but can be demagnetized by heat treatment, good anti rust and anti corrosion performance.
2. Hardness HRC22-26
c) Features of 316 316L stainless steel ball:
1. Austenitic steel, magnetic but can be demagnetized by heat treatment, high-grade steel balls, higher rust resistance and anti-corrosion, performance is superior to 304 stainless steel ball.
2. Hardness HRC22-26
d) Features of 420 stainless steel ball:
1. Martensitic steel, magnetic, good rust resistance, high hardness and precision
2. Hardness HRC50-55
e) Features of 440c stainless steel ball:
1. Martensitic steel, greatest hardness and surface finish, excellent anti rust and corrosion performance, high accuracy.
2. Hardness HRC58-65
