Stainless Steel ASTM A276 / AISI 309S Bars — Frequently Asked Questions
Find answers to common questions about AISI 309S Manufacturer production, grades (UNS S30908, EN 1.4833), standards (ASTM A276, ASME SA276), and applications.
AISI 309S (UNS S30908 / EN 1.4833) Stainless Steel is a low-carbon austenitic heat-resisting grade, primarily known for its excellent resistance to oxidation at high temperatures (up to 980°C / 1795°F), good strength at elevated temperatures, and crucially, *improved weldability* and *resistance to sensitization* compared to standard 309. This makes it ideal for welded structures operating in high-temperature environments. As an AISI 309S Manufacturer, we ensure these properties in every bar we supply, adhering to standards like DIN 17440 309S and JIS SUS309S.
While AISI 309 also offers excellent high-temperature oxidation resistance, AISI 309S is the preferred choice when fabrication involves welding and the component will be exposed to temperatures in the sensitization range (425-815°C / 800-1500°F). Its lower carbon content (the 'S' denotes low carbon) minimizes carbide precipitation at grain boundaries, thus preventing intergranular corrosion that can occur in the heat-affected zone of welds. Like 309, it outperforms 304/304L and 316/316L in dry, high-temperature oxidizing environments where weld integrity is paramount. Our ASTM A276 309S Supplier recommends it for demanding furnace parts, heat exchangers, and other high-temperature industrial components requiring welding, making us a trusted UNS S30908 Supplier.
DIPTI Metal Industries, an established ASTM A276 309S Supplier and UNS S30908 Stockiest, supplies AISI 309S 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 309S Round Bar Supplier and 309S Hex Bar Exporter, also offering ASME SA276 309S compliant products.
AISI 309S (UNS S30908) is widely recognized globally. Key equivalents include EN 1.4833 (Europe, low carbon variant of 1.4828), X8CrNi20-12 (Germany/EN), 309S25 (UK), Z6CN24-13 (France), and SUS 309S (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 1.4833 Manufacturer and ASTM A276 309S Exporter.
