What is stainless steel 446, and how does it perform in heat exchanger applications?

Stainless Steel 446 is a high-chromium ferritic stainless steel specifically designed for high-temperature applications, including heat exchangers. It contains a higher level of chromium than other stainless steel alloys, enhancing its resistance to oxidation and scaling at high temperatures. This alloy also offers excellent corrosion resistance, particularly against sulfur-bearing atmospheres, making it suitable for various heat exchanger environments.

Stainless steel 446 exhibits good thermal conductivity, ensuring efficient heat transfer within the exchanger. Its high strength and stability at elevated temperatures allow for reliable performance and extended service life in demanding heat exchange applications. Stainless steel 446 is a reliable choice for heat exchangers where elevated temperatures and corrosive conditions are prevalent.

What are the key properties and characteristics of stainless steel 446 heat exchanger tubes?

Stainless steel 446 heat exchanger tubes possess several key properties and characteristics that make them suitable for heat transfer applications. They exhibit excellent high-temperature oxidation resistance due to their high chromium content. This resistance helps prevent the formation of scales and ensures the tubes can withstand prolonged exposure to elevated temperatures without significant degradation. Stainless steel 446 tubes offer good corrosion resistance, particularly against environments containing sulfur compounds.

That makes them well-suited for heat exchangers operating in industries with corrosive gases or liquids. These tubes have high thermal conductivity, enabling efficient heat transfer within the exchanger, ultimately enhancing its overall performance. With its combination of high-temperature resistance, corrosion resistance, and thermal conductivity, stainless steel 446 heat exchanger tubes are favoured for applications where durability, reliability, and efficient heat transfer are paramount.

How does stainless steel 446 compare to other stainless steel alloys regarding corrosion and heat resistance?
In terms of corrosion resistance, stainless steel 446 performs well, especially against sulfur-bearing atmospheres, making it suitable for corrosive environments. However, compared to austenitic stainless steel alloys such as 304 and 316, stainless steel 446 may have slightly lower corrosion resistance in certain aggressive environments. Regarding heat resistance, stainless steel 446 is designed specifically for high-temperature applications. It exhibits good oxidation resistance and can withstand high temperatures without significant degradation, making it a reliable choice for heat exchanger applications with elevated temperatures.

Stainless Steel 446 Heat Exchanger Tube Manufacturing Process

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 Heat Exchanger Tube Mills

The production of Heat Exchanger 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, Heat Exchanger pipes and tubes may be produced continuously, increasing productivity while lowering costs and improving efficiency.

Continuous Casting

A notable advancement in the production of Heat Exchanger 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.
