Our steel plates for shipbuilding include: Grade AH32, AH36: A common steel quenched and tempered GL-E40 hull steel plate for shipbuilding that is typically formatted as heavy plates and fabricated surfaces for large, heavy-duty vessels like commercial ships and bulk carriers.Grade DH32, DH36: Another common shipbuilding steel used to construct and retrofit ship superstructures.Grade EH36: A desirable steel for shipbuilding that is available in prefabricated sections and heavy plates for hull construction and superstructure design.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the quenched and tempered GL-E40 hull steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between quenched and tempered GL-E40 hull steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
The tensile strength of seamless steel pipe is more than 8-10 times of that of ordinary steel, and its elastic modulus is better than that of steel, with excellent creep resistance, corrosion resistance and seismic resistance; the mechanical performance of seamless steel pipe is excellent, easy to machine, etc.; the seamless steel pipe quenched and tempered GL-E40 hull steel plate is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.
