Stainless Steel 304L Round Bars are cylindrical bars made of Stainless Steel 304L alloy, which is a low-carbon variant of Stainless Steel 304. These round bars are commonly used in various industries due to their excellent corrosion resistance, good formability, and weldability. Stainless Steel 304L offers excellent resistance to a wide range of corrosive environments, including chemical, atmospheric, and marine environments. The "L" in 304L stands for low carbon. This low carbon content helps to minimize carbide precipitation during welding, making it suitable for welding applications.
Stainless Steel 304L Round Bars can be easily formed and welded, making them suitable for various fabrication processes. While Stainless Steel 304L has good resistance to high temperatures, it is not recommended for use in extremely high-temperature applications like those exceeding 500°C (932°F) due to its lower carbon content. These round bars find applications in a wide range of industries including food processing, chemical processing, pharmaceuticals, petrochemicals, architecture, and construction and etc.
Stainless Steel 304L Round Bars are available in various surface finishes, including hot rolled, cold drawn, polished, and centerless ground finishes. The choice of finish depends on the specific application requirements and desired aesthetics. It is primarily composed of iron, chromium (typically around 18-20%), and nickel (approximately 8-10.5%). It also contains small amounts of manganese, silicon, phosphorus, sulfur, and carbon (typically less than 0.03%).
Melting and Casting
Steel and alloying metals are loaded into an electric arc furnace. Once in the furnace, the metal is heated to a specific temperature above its melting point, usually in excess of 2800°F.
Forming
Most cast steel is formed by hot rolling—the slab, bloom, or billet is heated and passed through large rollers, stretching out the steel into a longer, thinner form.
Heat Treatment
Heat treatment strengthens rolled steel by recrystallizing the deformed microstructure. Most steel is heat treated by annealing.
Cutting or Machining
Steel is cut to a specified shape and size. The steel can be sheared with circular knives, sawed with high-speed blades, or blanked with punches.
Finishing
Steels can be made with a wide variety of surface finishes. The chosen surface finish is not purely aesthetic. The type of finish is determined by the intended application.
