What is stainless steel 446, and what are its key properties?

Stainless Steel 446 Tube is ferritic stainless steel known for its excellent corrosion resistance and high-temperature strength. It belongs to the group of high-chromium ferritic alloys, with a composition that typically includes around 23% chromium. This high chromium content contributes to its remarkable resistance to various corrosive environments, including oxidizing and reducing atmospheres.

In addition to its corrosion resistance, Stainless Steel 446 exhibits remarkable mechanical properties, making it suitable for demanding applications. It possesses good tensile strength and creep resistance, allowing it to withstand high temperatures without losing its structural integrity. That makes stainless steel 446 a viable choice for applications that involve elevated temperatures, such as industrial furnaces, heat exchangers, and automotive exhaust systems.

Furthermore, stainless steel 446 offers excellent oxidation resistance, even at high temperatures, contributing to its longevity and reliability in challenging environments.

What are the typical applications for stainless steel 446 tubes?

Stainless Steel 446 Tubes find application in a wide range of industries due to their unique properties. They are commonly used in high-temperature environments such as industrial furnaces, where their exceptional heat and oxidation resistance are crucial. These tubes are also utilized in heat exchangers, efficiently transferring heat between fluids. Other applications include automotive exhaust systems, where the tubes withstand extreme temperatures and corrosive gases from combustion processes. Additionally, stainless steel 446 tubes are employed in chemical processing plants, oil refineries, and power generation facilities due to their corrosion resistance and ability to withstand harsh operating conditions.

How does stainless steel 446 compare to other steel grades regarding corrosion resistance?

In terms of corrosion resistance, stainless steel 446 possesses good resistance to a wide range of corrosive environments. While it may not exhibit the same level of corrosion resistance as some austenitic stainless steel grades, such as 316 or 304, it offers superior resistance to oxidation at high temperatures. Stainless steel 446's high chromium content provides excellent resistance against scaling and sulfidation, making it suitable for applications in high-temperature environments.

Stainless Steel 446 Tube Manufacturing Process

Welding Process

The grade and application requirements have an impact on tube welding and forming. For the manufacturing of tiny diameter tubes, we employ TIG welding. Steel sheets are coiled and welded inside of a welding machine. The steel sheets are shaped into a coil before entering the machine. The seam between these coils is then welded to create a tube.

Drawing/ Floating Process

Pulling a metal bar, rod, or wire through the entirety of a die to change its finish, shape, size, and/or mechanical qualities is known as floating or drawing. The tube's outer, inner, and wall thicknesses are all reduced via the tube drawing procedure. Stainless steel tubes benefit from maintaining the integrity of their surface.

Continuous Seamless Tube Mills

The production of seamless tubes has been transformed by continuous tube mills. These mills do away with the necessity for forging welding or filler metal, in contrast to conventional procedures. With the use of this technology, seamless pipes and tubes may be produced continuously, increasing productivity while lowering costs and improving efficiency.

Continuous Casting

A notable advancement in the production of seamless tubes is continuous casting. The metal is solidified into a continuous billet through the continuous pouring of molten metal into a water-cooled mould. Better uniformity and enhanced mechanical qualities are guaranteed by this continuous casting technique for the tubes.

Annealing

Metal is heated above the point of re-crystallization and cooled to room temperature during the annealing process. The molecular bonds in metal tighten when it is shaped, making it rigid. The metal is put through an annealing process to regain its ductility.

Sinking Process

Tube sinking is a drawing technique that reduces the diameter of tubes. In this drawing technique, a tube is run through a die without the need of a mandrel. Good inner surface quality is not ensured when using a mandrel. The die angel determines the integrity of the outer surface. The die being used produces a uniform surface. A tube can be significantly smaller than it was originally. When cost is a factor, tube sinking is ideal.

Inspection and Testing

Before sending our items to our consumers, we conduct inspection procedures to verify their integrity.
