Stainless steel contains nickel in what approximate range?

Explanation:
Stainless steel is an iron alloy that includes chromium for corrosion resistance, and nickel is added to stabilize the austenitic structure and improve ductility and toughness. The nickel content in common stainless steels typically ranges from about 8% to 35%. For example, grades like 304 and 316 have roughly 8–12% nickel, while some specialty grades use higher nickel up to the 20s or 30s. Values near zero percent would not provide stainless properties, and very high nickel levels (around 45% or more) would produce a different alloy system. Therefore, the approximate range is 8–35%.
