718 Stainless Steel Sheet: Properties, Applications & Benefits

718 stainless steel sheet, also known as Inconel 718 sheet, is a high-strength, corrosion-resistant nickel-chromium alloy primarily used in extreme environments. It is precipitation hardenable and designed to withstand high temperatures, pressure, and aggressive corrosion, making it ideal for aerospace, marine, and energy industries.

This alloy contains nickel, chromium, iron, niobium, and molybdenum, providing excellent mechanical properties and weldability. Unlike other high-strength materials, 718 stainless steel retains its strength even at cryogenic and elevated temperatures up to 1300°F (704°C).
