Known for their precision-engineered stainless steel products, this company specializes in corrosion-resistant flat bars designed for critical industrial applications. SS 317L, a low-carbon version of SS 317, boasts improved weldability and resistance to intergranular corrosion. Dhruv Metals offers these flat bars in a variety of dimensions and finishes, all while adhering to international quality standards like ASTM A240 and A276. With a commitment to prompt delivery and a customer-centric approach, Dhruv Metals caters to industries such as petrochemical, pharmaceutical, marine, and food processing, both in India and abroad.
Stainless Steel 317L is a low-carbon, molybdenum-bearing austenitic stainless steel alloy that contains about 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, with a maximum carbon content of 0.03%. This unique composition provides outstanding resistance to pitting, crevice corrosion, and intergranular attack after welding. On the mechanical side, SS 317L has a minimum tensile strength of 515 MPa, a yield strength of 205 MPa, and an elongation of around 35%. It retains good strength and toughness even at high temperatures, making it perfect for corrosive environments and applications that involve high-temperature service or welding processes.

Stainless Steel 317L is primarily composed of iron, with high levels of chromium (18-20%) and nickel (11-15%), along with molybdenum (3-4%) for enhanced corrosion resistance. It also contains small amounts of carbon, manganese, silicon, and phosphorus.
Yes, Stainless Steel 317L Flat Bar is highly resistant to corrosion, especially in harsh environments. Its high chromium, nickel, and molybdenum content enhances resistance to pitting, crevice corrosion, and general oxidation, making it ideal for chemical and marine applications.
Yes, Stainless Steel 317L Flat Bar can be welded easily using standard welding techniques such as TIG, MIG, and SMAW. Its low carbon content minimizes carbide precipitation during welding, ensuring strong joints and excellent corrosion resistance in the weld area.
Stainless Steel 317L Flat Bars are extensively used in industries that require exceptional corrosion resistance and structural reliability. They are particularly suited for chemical processing equipment like tanks, heat exchangers, and evaporators that come into contact with aggressive acids and halides. In the pharmaceutical and food processing sectors, 317L is preferred for its low carbon content, which helps reduce contamination and supports hygienic practices. The marine industry also benefits from its impressive resistance to saltwater corrosion. Furthermore, SS 317L Flat Bars find applications in pulp and paper manufacturing, power generation, textile machinery, and flue gas scrubbers, where durability and low maintenance are essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
