Stainless Steel Round Bar is one type of a product made in the stainless steel materials. There are different grades of stainless steels used in various industries. Stainless steel bars are used for their strength and corrosion resistance properties. Navstar Steel is a leading Stainless Steel Round Bar manufacturer in India. All stainless steels contain chromium. The composition can vary and the chromium content varies as well. The more the chromium content, the high the corrosion resistance is.

The bar is also known as the Stainless Steel Rod. The applications of the bars and rods depend on the requirement of the application and the grade of the materials. There are different specifications that specify the production and application types as well. The ASTM A276 Stainless Steel Bar is a specification for hot rolled and cold drawn bars except for forged bars. It can come in different shapes such as round, square, hexagon and other extruded shapes.
The Hot Rolled Stainless Steel Round Bar has more absolute roughness than the drawn bars. This is not a concern when the bars are used only for the strength and corrosion resistant properties. But when the bars are used in aesthetic applications and outdoor fixtures, the Cold Drawn Stainless Steel Round Bar is preferred because it has smooth surface and less absolute roughness. The bars can also vary in sizes. The general range is 5mm to 450mm radius. Please contact us for a complete SS Round Bar Size Chart and the pricing.
