How does the composition of stainless steel 347/347H differ
from other stainless steel grades used in heat exchanger
tubes?
The composition of stainless steel 347/347H distinguishes it
from other stainless steel grades commonly used in heat
exchanger tubes. Stainless steel 347 is a stabilized austenitic
stainless steel alloy containing chromium, nickel, and columbium
(niobium). Adding columbium/niobium offers exceptional
resistance to intergranular corrosion, especially in
high-temperature environments. This stabilization also prevents
sensitization, which is the formation of chromium carbides at
grain boundaries that can lead to intergranular corrosion. In
contrast, stainless steel 347H is a high-carbon version of 347,
which provides improved high-temperature strength.
The high carbon content enhances the material's ability to withstand elevated temperatures without significant deformation or creep. The higher carbon concentration also imparts greater resistance to sensitization, making stainless steel 347H particularly suitable for heat exchanger applications involving frequent exposure to high temperatures. Compared to other stainless steel grades used in heat exchanger tubes, the unique composition of stainless steel 347/347H offers excellent resistance to corrosion, intergranular attack, and thermal stresses, making it an ideal choice for demanding heat transfer applications.

What are the key properties of stainless steel 347/347H
Tubes?
Stainless steel 347 tubes possess several key properties that
make them highly desirable for various applications. They
exhibit excellent resistance to high temperatures, making them
suitable for heat exchangers, furnace components, and other
elevated-temperature environments. Adding columbium/niobium
provides exceptional intergranular corrosion resistance,
reducing the risk of corrosion and cracking. This characteristic
is particularly important in environments where the tubes are
exposed to sensitization due to extended exposure to high
temperatures. Additionally, stainless steel 347 tubes offer good
mechanical properties, including high tensile strength, creep
resistance, and toughness.
Stainless steel 347H tubes offer a range of key properties that make them highly advantageous for various applications. One of their notable properties is their exceptional high-temperature strength. With the addition of higher carbon content compared to stainless steel 347, stainless steel 347H tubes exhibit improved resistance to deformation and creep at elevated temperatures, making them suitable for applications that involve sustained exposure to heat. Moreover, stainless steel 347H tubes retain the excellent intergranular corrosion resistance provided by the columbium/niobium stabilization, preventing sensitization and the subsequent formation of chromium carbides at grain boundaries.

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.
