A Stainless Steel 304 Hex Bar is a six-sided bar stock made from grade 304 stainless steel, one of the most widely used stainless steel alloys. The hexagonal shape makes it easy to grip, machine, and use in fastening or structural applications. The hex bar is not just about its unique geometry; its strength comes from the composition of Stainless Steel 304 Hex Bar, which includes chromium and nickel as the primary alloying elements.
-
Chromium content: 18–20%
-
Nickel content: 8–10.5%
-
Carbon content: Up to 0.08%
This composition makes SS 304 hex bars resistant to rust, oxidation, and chemical corrosion, making them highly reliable.
