347 Stainless Steel Pipe & 347H Stainless Steel Pipe

Stainless steel 347 pipe and 347H Stainless Steel Pipe represent excellence in seamless and welded piping solutions. These pipes, fabricated from 347 and 347H stainless steel alloys, boast superior corrosion resistance, high-temperature stability, and impeccable mechanical properties. They are indispensable components in various industrial sectors, ensuring seamless fluid conveyance and structural integrity.

Stainless Steel 347 and 347H exhibit excellent corrosion resistance, particularly in acidic and chloride-containing environments. They also offer high-temperature strength and oxidation resistance, making them suitable for applications in elevated-temperature environments.

Stainless steel 347H pipe and 347H are austenitic stainless steels containing chromium, nickel, and small niobium. Adding niobium enhances their resistance to intergranular corrosion, making them suitable for high-temperature applications. Stainless Steel 347H has a higher carbon content than 347, improving high-temperature strength and creep resistance. We employ only the highest quality materials in producing its 347 and 347H Stainless Steel Pipes, adhering to stringent standards such as ASTM A213 and ASTM A269. The composition of these pipes typically comprises:

Chromium (Cr): 17% to 20%
Nickel (Ni): 9% to 13%
Niobium (Nb): 10x(C+N) min, 1.0% max
Carbon (C): 0.08% max
Manganese (Mn), Silicon (Si), Phosphorus (P), Sulfur (S): Variable amounts tailored to specific requirements.

Our 347 Stainless Steel Pipe and 347H Stainless Steel Pipe conform to many stringent international standards set forth by esteemed organizations, including ASTM, ASME, DIN, and AISI. ASTM A213 governs the specifications for seamless ferritic and austenitic alloy-steel boilers, superheaters, and heat-exchanger tubes, whereas ASTM A269 comprehensively covers seamless and welded austenitic stainless steel tubing for general service, ensuring uncompromising quality and performance.

We offer a diverse range of shapes and sizes for our 347 Stainless Steel Pipe and 347H Stainless Steel Pipe to suit the unique needs of our customers. Our pipes are available in various forms, including round, square, rectangular, and oval, with diameters ranging from small nominal to large ones for heavy-duty applications.

347 Stainless Steel vs 304

Stainless Steel 347 and 316 are austenitic stainless steels but differ in composition and properties. While both offer excellent corrosion resistance, 347 contains niobium, stabilizing the alloy against chromium carbide precipitation during welding and reducing the risk of intergranular corrosion. This makes 347 more suitable for high-temperature applications than 316. Additionally, 347 has higher strength at elevated temperatures compared to 316. However, 316 is more corrosion-resistant in chloride environments, such as those found in marine or coastal applications. The choice between 347 and 316 depends on the application’s specific requirements, with 347 favoured for elevated temperature environments and 316 for chloride-rich environments.
