Rupal Metals is a well-known Delhi-based manufacturer and supplier of Stainless Steel 304L Hollow Bars. Famous for offering high-quality stainless steel materials, the company engages in supplying corrosion-resistant and precisely engineered 304L hollow bars suited for various industrial applications. With a specialization in innovation, quality control, and prompt delivery, Rupal Metals provides services to clients from various sectors such as construction, petrochemical, and automotive. Their stainless steel manufacturing expertise provides excellent dimensional accuracy and strength, making them a first choice in the industry for robust and affordable hollow bar solutions of international standards.
Stainless Steel 304L Hollow Bar consists mainly of chromium (18–20%) and nickel (8–12%) with a maximum carbon content of 0.03%, which is beneficial in terms of weldability and minimizes intergranular corrosion risk. It also contains minor constituents such as manganese, silicon, phosphorus, and sulfur. This grade provides superior corrosion resistance, particularly in mildly corrosive conditions. Its mechanical properties are a minimum tensile strength of 485 MPa, yield strength of 170 MPa, and elongation of 35%, which makes it ideal for forming, machining, and structural use in different industries.

The low carbon content in SS 304L minimizes carbide precipitation during welding, reducing the risk of intergranular corrosion. This enhances weldability, making it ideal for applications requiring extensive welding without compromising corrosion resistance or mechanical properties.
SS 304L has superior corrosion resistance compared to SS 304 due to its lower carbon content, which minimizes carbide precipitation during welding. This reduces susceptibility to intergranular corrosion, making SS 304L ideal for welded structures in corrosive environments.
Stainless Steel 304L Hollow Bars find extensive application where high strength and corrosion resistance are needed. These are transportation systems for fluids and gases in chemical processing facilities, structural supports in building and construction, and precision-engineered parts in the automotive and marine industries. Their tubular construction saves weight while maintaining strength, so they are suited to load-carrying and pressure-sensitive applications. Also, they are appropriate for food processing, pharmaceutical, and dairy equipment because they possess hygienic characteristics and oxidation resistance, such that they provide long-term performance in severe service conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
