What is NV 690 Shipbuilding Steel Plate?
The NV690 shipbuilding steel plate is made with a precisely controlled chemical composition to ensure outstanding mechanical properties while keeping good weldability. The carbon content is kept low to maintain ductility, while manganese boosts strength and hardness. Silicon aids in deoxidation, and phosphorus and sulfur levels are strictly limited to enhance toughness. Micro-alloying elements like niobium, vanadium, titanium, and occasionally nickel refine the grain structure and bolster strength. Typically, NV690 offers a minimum yield strength of about 690 MPa, with tensile strength ranging from around 720 to 880 MPa, along with good elongation and excellent impact resistance at low temperatures.
