Stainless steel balls are made using a forged stainless steel process. Commonly used materials include 201, 302, 304, 316, 316L, 420, and 440C.
Definition of Stainless Steel: Stainless steel is a type of steel containing at least 12.5% chromium, offering high resistance to corrosion from chemicals (acids, alkalis, and salts).
Rust Prevention: Stainless steel balls are not rust-proof, but rather rust-resistant. This is because the addition of chromium forms a dense chromium oxide layer on the steel surface, effectively isolating the steel from air and preventing rust.
