Key Features of AISI 446 Stainless Steel
Stainless Steel AISI 446 (UNS S44600 / EN 1.4749) is a specialized high-chromium ferritic stainless steel, uniquely designed for extreme high-temperature and corrosive environments where traditional stainless steels or even austenitic heat-resisting alloys might falter. Its high alloy content provides exceptional resistance to various forms of high-temperature degradation. As a leading AISI 446 Supplier and ASTM A276 446 Stockiest, we highlight its core benefits:
Exceptional High-Temperature Oxidation Resistance
Offers unparalleled resistance to oxidation in continuous service up to 1100°C (2010°F) in air, and good resistance to scaling, making it suitable for the most severe furnace applications, from an expert AISI 446 Manufacturer.
Excellent Sulfidation Resistance
Specifically developed for and exhibits superior resistance to sulfidation (attack by sulfur-containing gases) at elevated temperatures, a critical property for many industrial heating processes, fulfilling requirements of an EN 1.4749 Exporter.
Non-Hardenable & Ferritic Structure
As a ferritic grade, 446 is non-hardenable by heat treatment, which simplifies fabrication. Its ferritic microstructure also contributes to its resistance against stress corrosion cracking, meeting BS 970 446S61 standards.
Moderate Formability & Weldability
While not as formable or weldable as austenitic grades, it can be formed and welded using appropriate techniques, typically with preheating and post-weld heat treatment to maintain ductility, compliant with AFNOR Z18CD26.
Magnetic Properties
Being a ferritic stainless steel, AISI 446 is magnetic in all conditions, which can be a distinguishing characteristic for certain specialized applications, from a reliable GOST 15Х25Т Supplier.
Globally Accepted for Severe Environments
A globally recognized and preferred grade for many critical, extreme high-temperature and corrosive applications, ensuring wide compatibility, thanks to our global network as an AS 446 Exporter.
International Standards & Worldwide Equivalents of AISI 446
As a global ASTM A276 AISI 446 Manufacturer and UNS S44600 Exporter, we ensure our products meet or exceed the requirements of various international standards, making them suitable for projects worldwide. This includes compliance as an EN 1.4749 Manufacturer and ASME SA276 446 Supplier.

Stainless Steel ASTM A276 / AISI 446 Bars — Frequently Asked Questions
Find answers to common questions about AISI 446 Manufacturer production, grades (UNS S44600, EN 1.4749), standards (ASTM A276, ASTM A240, ASTM A182, ASME SA276, ASME SA240, ASME SA182), and applications.
AISI 446 (UNS S44600 / EN 1.4749) Stainless Steel is a high-chromium ferritic grade, specifically known for its *exceptional resistance to high-temperature oxidation* (up to 1100°C / 2010°F) and excellent resistance to sulfidation. It is a non-hardenable stainless steel with good ductility and is magnetic in all conditions. Its high chromium content provides superior performance in severe high-temperature corrosive environments. As an AISI 446 Manufacturer, we ensure these properties in every bar we supply, adhering to standards like DIN 17440 446 and JIS SUH446.
AISI 446 is primarily selected for its *superior resistance to sulfur attack* and *high-temperature oxidation resistance* in extreme environments where even 310/309 might struggle, especially in conditions involving reducing sulfurous atmospheres. While austenitic grades like 310 offer good high-temperature strength, 446's high chromium content (23-27%) makes it outstanding in resisting corrosive gases at elevated temperatures, particularly sulfidation. It is a ferritic grade, so it is not as strong as austenitic grades at high temperatures, but its corrosion resistance profile is unique and highly beneficial for specific furnace and industrial heating applications. Our ASTM A276 446 Supplier recommends it for applications benefiting from this exceptional high-temperature corrosion resistance, making us a trusted UNS S44600 Supplier.
DIPTI Metal Industries, an established ASTM A276 446 Supplier and UNS S44600 Stockiest, supplies AISI 446 bars in various profiles including Round Bars, Square Bars, and Hexagonal Bars, as well as Rods. Finishes include Hot Rolled, Cold Drawn, and Annealed, with the annealed condition being most common for formability in high-temperature component fabrication, catering to different precision and surface quality requirements. We are a prominent 446 Round Bar Supplier and 446 Hex Bar Exporter, also offering ASME SA276 446 compliant products.
AISI 446 (UNS S44600) is widely recognized globally. Key equivalents include EN 1.4749 (Europe), X18CrN28 (Germany/EN), 446S61 (UK), Z18CD26 (France), and SUH446 (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 1.4749 Manufacturer and ASTM A276 446 Exporter.
