Key Features of AISI 317L Stainless Steel
Stainless Steel AISI 317L (UNS S31703 / EN 1.4438) is a premium low-carbon austenitic grade, specifically engineered for applications demanding superior corrosion resistance beyond that offered by 316L stainless steel, combined with excellent weldability. Its higher molybdenum content makes it exceptionally resistant to localized corrosion like pitting and crevice corrosion, particularly in aggressive acidic and chloride-containing environments, while low carbon prevents sensitization. As a leading AISI 317L Supplier and ASTM A276 317L Stockiest, we highlight its core benefits:
Superior Pitting & Crevice Corrosion Resistance
The higher molybdenum content (3-4%) significantly enhances resistance to pitting and crevice corrosion, especially in chloride-rich environments like seawater and industrial chemicals, from an expert AISI 317L Manufacturer.
Excellent Sulfuric Acid Resistance
Offers improved resistance to sulfuric acid solutions, particularly at elevated temperatures, distinguishing it from lower alloyed grades and fulfilling requirements of an EN 1.4438 Exporter.
Improved Weldability & Sensitization Resistance
The ultra-low carbon content (max 0.03%) minimizes carbide precipitation during welding or exposure to high temperatures, significantly reducing the risk of intergranular corrosion in the heat-affected zone, meeting BS 970 317L standards.
Good General Corrosion Resistance
Retains excellent general corrosion resistance in a wide array of aggressive chemical process environments, compliant with AFNOR Z3CND18-13-05.
Excellent Fabricability
Can be readily formed and welded using standard austenitic stainless steel practices, providing superior versatility in manufacturing complex, corrosion-resistant components, from a reliable GOST 03Х17Н14М3 Supplier.
Widely Accepted Globally
A globally recognized and preferred low-carbon grade for many critical, highly corrosive industrial applications requiring welding, ensuring wide compatibility, thanks to our global network as an AS 317L Exporter.

Stainless Steel ASTM A276 / AISI 317L Bars — Frequently Asked Questions
Find answers to common questions about AISI 317L Manufacturer production, grades (UNS S31703, EN 1.4438), standards (ASTM A276, ASME SA276), and applications.
AISI 317L (UNS S31703 / EN 1.4438) Stainless Steel is a low-carbon austenitic chromium-nickel-molybdenum grade known for its significantly enhanced corrosion resistance compared to 316L and standard 317 stainless steel. Its higher molybdenum content provides superior resistance to pitting and crevice corrosion, particularly in aggressive environments containing chlorides and various acids, including sulfuric acid. Critically, its low carbon content (the 'L' denotes low carbon) ensures excellent weldability and resistance to sensitization (intergranular corrosion) after welding. As an AISI 317L Manufacturer, we ensure these properties in every bar we supply, adhering to standards like DIN 17440 317L and JIS SUS317L.
AISI 317L improves upon both 316L and standard 317. Compared to 316L, 317L has a higher molybdenum content (3.0-4.0% vs. 2.0-3.0%), providing *superior pitting and crevice corrosion resistance*. Compared to standard 317 (which also has high Mo), 317L has a *lower carbon content (max 0.03%)*, which minimizes carbide precipitation during welding or exposure to temperatures in the sensitization range (425-815°C / 800-1500°F). This makes 317L the preferred choice for welded structures in highly corrosive environments, preventing intergranular corrosion in the heat-affected zone. It is widely used in aggressive chemical processing, pulp and paper, and pollution control applications where weld integrity and maximum corrosion resistance are critical. Our ASTM A276 317L Supplier recommends it for challenging industrial conditions, making us a trusted UNS S31703 Supplier.
DIPTI Metal Industries, an established ASTM A276 317L Supplier and UNS S31703 Stockiest, supplies AISI 317L bars in various profiles including Round Bars, Square Bars, and Hexagonal Bars, as well as Rods. Finishes include Hot Finished, Cold Drawn, and Bright Bars, catering to different precision and surface quality requirements for corrosive and welded environments. We are a prominent 317L Round Bar Supplier and 317L Hex Bar Exporter, also offering ASME SA276 317L compliant products.
AISI 317L (UNS S31703) is widely recognized globally. Key equivalents include EN 1.4438 (Europe), X2CrNiMo18-15-4 (Germany/EN), 317S16 (UK), Z3CND18-13-05 (France), and SUS 317L (Japan). It adheres to specifications like ASTM A276, ASTM A240, ASTM A182 and ASME SA276, ASME SA240, ASME SA182, EN 10088-3, DIN 17440, BS 970, NF A35-573, JIS G4303, GB/T 1220, GOST 5632, UNI 6900, and AS 1449, ensuring global compliance from an EN 1.4438 Manufacturer and ASTM A276 317L Exporter.
