Informational Guide on SS 446 Round Bars

High chromium ferritic heat-resistant alloy SS 446 round bars exhibit outstanding resistance to oxidation, sulfidation, and other types of hot corrosion. The ferritic stainless steel grade 446 is non-heat treatable and offers good resistance to oxidation and corrosion at high temperatures. Due to the higher carbon content, SS 446 bars are a low interstitial variant of stainless steel. Many of the SS 446 Round Bars Suppliers offer these bars in various sizes and grades. The enhanced tensile stress and tougher nature of these stainless steels come at the expense of ductility and weldability. The addition of silicon improves magnetic permeability and reduces hysteresis losses.

Properties of SS 446 Round Bars

Aged and solution treated & excellent resistance to stress corrosion cracking can be found in SS 446 Bar. In ambient settings, SS 446 exhibits good resistance to sulfuric gases and oxidation. Additionally, alloy 446 stainless steel is more resistant to oil ash corrosion. A high chromium ferritic heat-resistant alloy with outstanding resistance to sulfidation, oxidation, and other types of hot corrosion, the SS 446 Round Bar is available in a variety of sizes. This grade is frequently used for furnace parts and boiler baffles because of its exceptional oxidation resistance at high temperatures.

Features of Stainless Steel 446 Rods

The ASTM A276/ASME SA-276 specification for wrought stainless steel bars is broken down into several forms and shapes, such as SS 446 round bars, rods, channel bars, T-bars, flat bars, blocks, square bars, triangle bars, threaded bars, hex (A/F), profiles, half ingots, billets, and I/H bars. The material must be provided in one of the following ways when considering wrought stainless round bars: hot-worked, hot-worked and annealed, hot-worked-annealed and cold worked, or hot-worked-annealed and heat treated. Round bars can have a variety of surface finishes, including black, bright polished, rough turned, NO.4 finish, matte finish, BA finish, 2B, 2D, etc., depending on how they are treated, used, and applied.

Applications and Uses

Medical equipment, food industry, building construction, construction materials for the marine environment, and electric equipment are just a few of the diverse uses for SS 446 bars. Because SS 446 is durable at high temperatures and is employed in non-sulfuric environments, raised temperature applications are common.
