Seamless Incoloy 926 Tube

Seamless Incoloy 926 tube

Seamless Incoloy 926 tube is a high-performance superaustenitic stainless steel alloy tube. It is made by advanced cold-rolling or hot-extrusion processes. These processes ensure the tube has a dense internal structure and no seam defects. Seamless Incoloy 926 tube is a nickel-iron-chromium-based high-temperature corrosion-resistant material. The typical chemical composition of Seamless Incoloy 926 tube is: nickel (Ni) 24-26%, chromium (Cr) 19-21%, molybdenum (Mo) 6.0-7.0%, copper (Cu) 0.5-1.5%, nitrogen (N) 0.15-0.25%. It also contains small amounts of carbon (C) and manganese (Mn). This optimized composition design makes Seamless Incoloy 926 tube keep excellent mechanical properties and corrosion resistance in extreme corrosive and high-temperature environments.

Seamless Incoloy 926 tube is ideal for tough conditions. It has advantages like corrosion resistance, high-temperature strength and long life. It is perfect for situations where common stainless steels like 316Ti and 904L don't work. Seamless Incoloy 926 tube is widely used and reliable. It is a key material solution in industries like chemical, energy and marine engineering.

Features of Seamless Incoloy 926 tube

Excellent Corrosion Resistance
Seamless Incoloy 926 tube performs well in strong acids, strong alkalis, chlorides, and sulfur-containing media. It is especially suitable for high-concentration chloride environments, such as seawater, brine, and chemical waste liquids. Seamless Incoloy 926 tube has much better resistance to pitting (PREN≥40) and stress corrosion cracking (SCC) than regular stainless steels.

High-Temperature Oxidation and Mechanical Stability
Thanks to the strengthening effect of high nickel and nitrogen content, Seamless Incoloy 926 tube can keep good creep resistance and oxidation resistance at high temperatures (below 600°C). It is suitable for heat exchange systems and high-temperature furnace tubes.

High Strength and Good Workability
Compared to ordinary austenitic stainless steel, Seamless Incoloy 926 tube has higher yield strength and tensile strength. It still has good cold workability, like bending and flaring. It can also be welded by methods such as TIG welding and laser welding.

Long Life and Cost-Effectiveness
Seamless Incoloy 926 tube costs more than 304/316 stainless steel at first. But its very long service life and low maintenance needs, like anti-scaling and resistance to erosion corrosion, make it more cost-effective in fields like chemical and energy industries.

Applications of Seamless Incoloy 926 tube

Petroleum and Petrochemical Industry
Seamless Incoloy 926 tube is used in piping systems for highly corrosive fluids like concentrated sulfuric acid, hydrochloric acid, and phosphoric acid.
Seamless Incoloy 926 tube is often used in high-temperature and high-pressure pipelines in catalytic cracking units and hydrogenation reactors.

Marine and Seawater Treatment
Seamless Incoloy 926 tube is used in seawater desalination systems, such as evaporator tubes that resist salt spray corrosion and high-pressure reverse osmosis (RO) membrane shell components.
Seamless Incoloy 926 tube is used in seawater cooling systems, subsea oil pipelines, and pump and valve components.

Energy and Environmental Engineering
Seamless Incoloy 926 tube is used in flue gas desulfurization (FGD) for scrubber spray pipes and chimney liners to resist SO₂ and wet chlorine corrosion.
In nuclear power and waste incineration, Seamless Incoloy 926 tube is often used in high-temperature corrosion-resistant components like nuclear waste storage containers and incinerator heat exchanger tubes.

Food and Pharmaceutical Industry
In sterile fluid transfer, Seamless Incoloy 926 tube is used in piping for fermentation tanks that meet FDA standards and in Clean-In-Place (CIP) systems.

Other High-End Industries
Aerospace: High-strength corrosion-resistant tubing for fuel hydraulic systems.
Semiconductor Manufacturing: Piping for ultrapure water (UPW) transfer to prevent ion contamination.
