Product Description

AISI 446 Stainless Steel Bar: A High-Performance Ferritic Alloy for Demanding Applications

AISI 446 stainless steel bar stands out as a premium ferritic stainless steel product, engineered to deliver exceptional performance in harsh and high-temperature environments. Classified under the ferritic category due to its iron-chromium composition (with no significant nickel content), this stainless steel bar is distinguished by its unique chemical makeup, which includes a high chromium content ranging from 23% to 27%, a low carbon content (typically ≤ 0.20%), and trace elements such as silicon and manganese that enhance its overall mechanical and chemical properties. As an equivalent to grades like UNS S44600 and DIN 1.4762, AISI 446 stainless steel bar has become a trusted choice in industries where resistance to oxidation, sulfidation, and general corrosion is non-negotiable.

One of the most notable advantages of AISI 446 stainless steel bar is its outstanding high-temperature resistance. Unlike many other stainless steel grades that lose structural integrity at elevated temperatures, AISI 446 maintains excellent stability even when exposed to continuous operating temperatures up to 1,100°C (2,012°F). This makes it particularly suitable for applications involving heat exposure, as it resists scaling, oxidation, and thermal fatigue-common issues that lead to premature component failure. Additionally, its high chromium content forms a dense, adherent oxide layer on the surface, which acts as a protective barrier against corrosive substances, including sulfur-containing gases, acids, and industrial chemicals. This corrosion resistance is further enhanced by its low carbon content, which minimizes the risk of intergranular corrosion, a critical factor in applications requiring long-term reliability.

In terms of mechanical properties, AISI 446 stainless steel bar offers a well-balanced combination of strength and ductility. It typically exhibits a tensile strength of 550-750 MPa, a yield strength of ≥ 300 MPa, and an elongation of ≥ 15%, making it suitable for a wide range of forming and machining processes. Whether it's being cut, welded, bent, or machined into complex shapes, this stainless steel bar maintains its structural integrity, reducing the risk of cracks or deformation during processing. Its uniform microstructure, achieved through strict quality control during production, ensures consistent performance across every batch, a key requirement for industrial applications where precision and reliability are paramount.

Our AISI 446 stainless steel bar is manufactured in compliance with international standards, including ASTM, AISI, and DIN, ensuring it meets the rigorous quality requirements of global industries. The production process begins with the selection of high-purity raw materials, followed by melting, casting, hot rolling, and heat treatment-each step monitored by advanced testing equipment to guarantee chemical composition accuracy and mechanical property consistency. We offer the bar in a variety of sizes, ranging from 5mm to 200mm in diameter, and can customize lengths and surface finishes (such as bright, peeled, or polished) to meet specific customer needs.

The versatile nature of AISI 446 stainless steel bar makes it ideal for a diverse range of applications. It is widely used in the manufacturing of industrial furnace components (such as heating elements, furnace liners, and radiant tubes), heat exchangers, automotive exhaust systems, catalytic converters, and high-temperature structural parts in power plants and chemical processing facilities. Its corrosion resistance also makes it suitable for use in marine environments, food processing equipment, and medical devices where hygiene and durability are essential.

As a direct manufacturer, we are able to offer AISI 446 stainless steel bar at competitive factory prices without compromising on quality. We provide comprehensive after-sales support, including technical consultation, material testing reports, and timely delivery to ensure a seamless purchasing experience. Whether you require small batches for prototype development or large quantities for mass production, our AISI 446 stainless steel bar is the reliable, cost-effective solution for your high-performance material needs.

446 is a high-chromium, ferritic heat resistant alloy with excellent resistance to oxidation, sulfidation and other forms of hot corrosion. This grade is most commonly used between 1500 - 2100°F, although its elevated temperature strength is quite low. 446 is the only heat resistant alloy that will tolerate molten copper and brass. As with other high chromium ferritic stainless, 446 embrittles severely in the 700-1000°F temperature range (885°F embrittlement). 446 should not be used in this temperature range unless nearly complete loss of room temperature ductility may be tolerated. Sigma phase embrittlement occurs upon long time exposure in the 1000-1300°F range.

446 has a high ductile-to-brittle impact transition temperature. Therefore, successful forming and bending is aided by low forming speeds, edge preparation and preheating to 250-400°F. Annealing, when necessary should be performed at 1550-1650°F followed by rapid cool.

Welding may be accomplished by conventional methods. Preheating and postheating to 300-600°F is helpful. Austenitic weld fillers, such as AWS E310 or E312 are generally suggested to maximize weld deposit ductility.
