Steel sheet pile are steel profiles with interlocking edges. They are driven into the ground to provide excavation support. These sheet piles are used to support walls, clear land, create underground structures, and river bank or coastal protection.

Z-shaped steel sheet pile and U-shaped steel sheet pile
Of all sheet piles, Z-shaped sheet piles are most similar to U-shaped sheet piles.

Stainless steels bond around a key material property: excellent corrosion resistance, attributable to high chromium content (> 10.5% by mass) and low carbon content (<1.2% by mass). Beyond the corrosion resistance, the mechanical properties of these steels can vary greatly according to the family to which they belong.

General Properties
Alloy 330 (UNS N08330) is an austenitic nickel-iron-chromium alloy developed to provide excellent resistance to carburizing and oxidizing atmospheres at elevated temperatures. With a nickel content of 34 to 37 percent, the alloy remains highly resistant to both chloride stress corrosion cracking and embrittlement from the precipitation of sigma phase.
