The yield strength of AH36, DH36, , EH36, and FH36 Steel for high-strength hull structure is not less than 355MPa, and the tensile strength is 490 ~ 620MPa The letter A, D, E, and F indicate the impact toughness that they can achieve at 0°C, -20°C, -40°C and -60°C respectively The yield strength of Grade AH40, DH40, EH40, FH40 hull structural steel is not less than 390MPa, the tensile strength is 510 ~ 660MPa,DH32 hull structure steel.DH32 hull structure steel,Our company was founded in 2000, which initially committed to providing high-quality steel products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export steel to the international market, opening up the international steel market.No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than Annealing and normalizing are better than quenching and tempering No 45 steel has higher strength and better machinability than Q345 steel After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance No 45 steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding Preheating is required before welding, and stress relief annealing shall be conducted after welding,DH32 hull structure steel.Hot rolled seamless tube is usually produced on automatic tube rolling mill. After the solid tube blank is inspected and the surface defects are removed, it is cut to the required length, centered on the end face of the piercing end of the tube blank, then sent to the heating furnace for heating, and perforated on the piercing machine.DH32 hull structure steelRespect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.DH32 hull structure steel
