What is FH 620 Shipbuilding steel plate?
The FH620 shipbuilding steel plate is made with a carefully controlled chemical composition to ensure outstanding mechanical performance while also being easy to weld. 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. Additionally, micro-alloying elements like niobium, vanadium, titanium, and sometimes nickel refine the grain structure and bolster strength. Typically, FH620 delivers a minimum yield strength of around 620 MPa, with tensile strength ranging from about 650 to 820 MPa, along with good elongation and excellent impact resistance at low temperatures.
