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.
Rolling and welding
Aluminum Pipes & Tubes may undergo rolling processes to refine their dimensions and improve surface finish. Welding techniques like TIG or MIG welding are utilized for this process
Cleaning and heating phase
These Pipes & Tubes are subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes.
Cold - drawing process
The Pipes & Tubes are coated with oxalic and soap solution. In the cold drawing process, the tube or pipe is drawn over the bench using Die plugs.
Finishing process
The stainless tubes or pipes thus produced will undergo certain testing and quality checks. This process is followed by proper packing and dispatch.
