SUS 347H Pipes are high-temperature stainless steel pipes widely used in industries where strength, corrosion resistance, and durability are important. These pipes are made from stabilized stainless steel that contains columbium (niobium), which helps prevent carbide precipitation during welding and high-temperature service. Because of this property, SUS 347H pipes are ideal for applications that involve continuous exposure to elevated temperatures.
The “H” in 347H indicates a higher carbon content compared to standard 347 stainless steel. This increased carbon level improves the material’s strength at high temperatures, making it suitable for demanding industrial environments. SUS 347H pipes are commonly used in power plants, chemical processing industries, oil and gas sectors, and heat exchangers where reliability and long service life are essential.

Features of SUS 347H Pipes
SUS 347H Pipes offer several useful features that make them suitable for industrial use. One of the most important benefits is their excellent resistance to intergranular corrosion. The addition of niobium stabilizes the alloy ...
... and prevents the formation of chromium carbides at grain boundaries, which helps maintain corrosion resistance even after welding.
These pipes also provide strong resistance to oxidation and scaling at high temperatures. They perform well in conditions where temperatures may reach up to 800°C or more. This property makes them widely used in boiler tubes, furnace components, and high-temperature piping systems.
Another advantage of SUS 347H pipes is their good weldability and formability. Manufacturers can easily fabricate them into different pipe shapes and sizes without compromising their structural integrity. Their durability and ability to perform under stress make them a dependable option for industrial piping systems.
Applications of SUS 347H Pipes
SUS 347H pipes are used in a wide range of industries due to their strength and corrosion resistance. In the power generation sector, they are often used in superheaters, reheaters, and steam pipelines where high temperatures and pressure are common.
The chemical processing industry also uses these pipes for transporting corrosive chemicals and high-temperature fluids. Their resistance to corrosion and oxidation helps maintain safety and performance in demanding environments.
In the oil and gas industry, SUS 347H pipes are used in refinery equipment, heat exchangers, and pressure piping systems. They are also commonly used in petrochemical plants where equipment must operate reliably for long periods under harsh conditions.
