Vipul Sheets and Plates is a leading supplier of Stainless Steel 317L Hollow Bars in Delhi, India, offering high-quality stainless solutions for demanding applications. SS 317L is a low-carbon, molybdenum-bearing austenitic stainless steel known for its improved corrosion resistance, particularly against chlorides and sulfates. Hollow bars provide a cost-effective option for machining thicker components while minimizing material waste. Our 317L hollow bars are used in the petrochemical, pulp and paper, and chemical processing industries. Vipul ensures precise dimensional tolerance, strong structural integrity, and custom lengths, delivering consistent performance even in aggressive and corrosive environments.
Stainless Steel 317L consists of 18–20% Chromium, 11–15% Nickel, 3–4% Molybdenum, and less than 0.03% Carbon. The alloy provides better protection against pitting, crevice corrosion, and stress corrosion cracking. It has a tensile strength of 515 MPa, yield strength of 205 MPa, and good ductility (elongation ≥ 35%). SS 317L retains strength at high temperatures and offers good weldability. The low carbon content reduces carbide precipitation during welding, promoting resistance to intergranular corrosion. Hollow bars result in material savings for components that require drilling or internal machining.

The low carbon content of SS 317L reduces the risk of carbide precipitation at high temperatures, preventing grain boundary corrosion. This enhances its stability, weldability, and overall performance, making it more reliable in high-temperature environments, especially in corrosive conditions.
SS 317L Hollow Bars offer excellent corrosion resistance, particularly against chlorides and acidic environments, making them ideal for marine and chemical processing industries. Their high strength, durability, and resistance to pitting and crevice corrosion ensure long-lasting performance in harsh conditions.
Stainless Steel 317L Hollow Bars are frequently used in corrosive processing industries such as pulp and paper, petrochemicals, pharmaceuticals, and marine applications. These bars are ideal for creating valves, hollow shafts, bushings, heat exchanger tubes, and pump components. Thanks to their strength and corrosion resistance, they are used in condenser tubing, offshore structures, and flue gas scrubbers. The hollow design cuts down on machining time and material costs, making them effective for precision components. Their use in structural applications where cutting weight is important makes them a preferred option in performance-driven and cost-conscious industries.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
