Stainless Steel ASTM A276 / AISI 309 Bars — Frequently Asked Questions
Find answers to common questions about AISI 309 Manufacturer production, grades (UNS S30900, EN 1.4828), standards (ASTM A276, ASME SA276), and applications.
AISI 309 (UNS S30900 / EN 1.4828) Stainless Steel is an austenitic heat-resisting grade, primarily known for its excellent resistance to oxidation at high temperatures (up to 980°C / 1795°F) and good strength at elevated temperatures. It also offers good resistance to intergranular corrosion. As an AISI 309 Manufacturer, we ensure these properties in every bar we supply, adhering to standards like DIN 17440 309 and JIS SUS309.
AISI 309 is designed for continuous service at temperatures up to 980°C (1795°F) due to its higher chromium and nickel content, which provides superior oxidation resistance and elevated temperature strength compared to 304/304L. While 316/316L offer better aqueous corrosion resistance (due to molybdenum), 309 excels in dry, high-temperature oxidizing environments where corrosion is less of a concern. Our ASTM A276 309 Supplier recommends it for demanding furnace parts, heat exchangers, and other high-temperature industrial components, making us a trusted UNS S30900 Supplier.
DIPTI Metal Industries, an established ASTM A276 309 Supplier and UNS S30900 Stockiest, supplies AISI 309 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 high-temperature components. We are a prominent 309 Round Bar Supplier and 309 Hex Bar Exporter, also offering ASME SA276 309 compliant products.
AISI 309 (UNS S30900) is widely recognized globally. Key equivalents include EN 1.4828 (Europe), X15CrNiSi20-12 (Germany/EN), 309S24 (UK), Z15CN24-13 (France), and SUS 309 (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 1.4828 Manufacturer and ASTM A276 309 Exporter.
