Question 1

How do Super Duplex Steel Sheets compare to austenitic stainless steels?

Accepted Answer

Compared to conventional austenitic stainless steels like 304 or 316, Super Duplex Steel Sheets offer nearly double the yield strength and significantly better resistance to stress corrosion cracking. While 316L may fail in high-chloride conditions, Super Duplex alloys perform reliably due to their duplex microstructure and high alloy content. This makes them more suitable for heavy-duty environments such as offshore platforms, heat exchangers, and seawater systems, while also offering cost-efficiency through thinner gauges and extended durability.

Question 2

How are Super Duplex Steel Sheets packaged for bulk supply?

Accepted Answer

For bulk supply, Super Duplex Steel Sheets are securely packed in wooden crates or pallets, with plastic or foam wrapping to prevent surface scratches and moisture exposure. Sheets are separated with protective layers to avoid damage during transit. International packaging standards are followed to ensure safe shipping by sea or air. This ensures that large orders reach customers in construction, marine, and fabrication industries in optimal condition.

Question 3

Are Super Duplex Steel Sheets suitable for welding and fabrication?

Accepted Answer

Yes, Super Duplex Steel Sheets offer excellent weldability with proper precautions. They require controlled heat input and interpass temperatures during welding to maintain the balance between the austenite and ferrite phases. Welded joints retain high strength and corrosion resistance when using matching filler metals. These sheets can be sheared, bent, and formed with standard fabrication methods, making them ideal for custom components in the oil & gas, chemical, and power sectors.
