Its higher molybdenum content makes it exceptionally resistant to localized corrosion like pitting and crevice corrosion, particularly in aggressive acidic and chloride-containing environments. As a leading AISI 317 Supplier and ASTM A276 317 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, making it ideal for marine and chemical applications, from an expert AISI 317 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 1.4449 Exporter.
Good General Corrosion Resistance
Retains excellent general corrosion resistance in a wide array of aggressive chemical process environments, meeting BS 970 317S12 standards.
Good Fabricability & Weldability
Can be readily formed and welded using standard austenitic stainless steel practices, providing versatility in manufacturing complex components, compliant with AFNOR Z8CND18-13-05.
Good High-Temperature Strength
While primarily a corrosion-resistant grade, it also exhibits good strength at elevated temperatures, though not intended for the extreme temperatures of 309/310 grades, from a reliable GOST 08Х17Н13М3Т Supplier.
Widely Accepted Globally
A globally recognized and preferred grade for many critical, highly corrosive industrial applications, ensuring wide compatibility, thanks to our global network as an AS 317 Exporter.

Stainless Steel ASTM A276 / AISI 317 Bars — Frequently Asked Questions
Find answers to common questions about AISI 317 Manufacturer production, grades (UNS S31700, EN 1.4449), standards (ASTM A276, ASME SA276), and applications.
AISI 317 (UNS S31700 / EN 1.4449) Stainless Steel is an austenitic chromium-nickel-molybdenum grade known for its significantly enhanced corrosion resistance compared to 316 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. It also offers good strength and excellent fabricability. As an AISI 317 Manufacturer, we ensure these properties in every bar we supply, adhering to standards like DIN 17440 317 and JIS SUS317.
AISI 317 contains a higher percentage of molybdenum (3.0-4.0% for 317 compared to 2.0-3.0% for 316), and often slightly higher chromium and nickel. This increased alloy content gives 317 superior resistance to general corrosion, pitting, and crevice corrosion, especially in environments with chlorides or sulfuric acid. It is preferred over 316 in more aggressive chemical processing, pulp and paper, and marine applications where enhanced corrosion resistance is critical for longevity and performance. Our ASTM A276 317 Supplier recommends it for challenging industrial conditions, making us a trusted UNS S31700 Supplier.
DIPTI Metal Industries, an established ASTM A276 317 Supplier and UNS S31700 Stockiest, supplies AISI 317 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 environments. We are a prominent 317 Round Bar Supplier and 317 Hex Bar Exporter, also offering ASME SA276 317 compliant products.
AISI 317 (UNS S31700) is widely recognized globally. Key equivalents include EN 1.4449 (Europe), X5CrNiMoN17-13-3 (Germany/EN), 317S12 (UK), Z8CND18-13-05 (France), and SUS 317 (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 1.4449 Manufacturer and ASTM A276 317 Exporter.
