ASME SA213 / ASTM A213 TP347H Stainless Steel Seamless Tube Heat Exchanger Tube

ASTM A213 / ASME SA213 TP347H Stainless Steel Seamless Tube Heat Exchanger Tube

Compared to other grades of steel, 347H has certain advantages:

1. High temperature resistance: Steel 347H exhibits excellent heat resistance, making it suitable for applications where materials are subjected to elevated temperatures.

2. Enhanced corrosion resistance: This grade contains a higher level of chromium and columbium (niobium) than standard austenitic stainless steels. As a result, 347H offers improved resistance to corrosion, especially in environments with high concentrations of acids, such as sulfuric, acetic, and phosphoric acids.

3. Weldability: Steel 347H is known for its good weldability. It can be easily welded using standard welding techniques, such as TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) welding, without experiencing significant issues like sensitization or cracking.

4. Stability against intergranular corrosion: One of the primary advantages of 347H is its ability to resist intergranular corrosion, which can occur in certain environments or after exposure to high temperatures. This stability is due to the addition of columbium, which forms carbides that inhibit the precipitation of chromium carbides, thus preventing sensitization and intergranular corrosion.

5. Versatility: Steel 347H finds utility in a wide range of applications, including chemical processing, oil and gas industry, pharmaceuticals, food processing, and high-temperature environments like furnace equipment and heat exchangers.
