1. Introduction to AH36/EH36 steel plate AH36/EH36 is a shipbuilding steel plate certified by a classification society. It is implemented in accordance with the standards of nine-nation classification societies. The impact temperature of EH36 steel plate is -40 degrees. The same DH36, EH36 and FH36 steel plates are all high-strength ship plates. The China Classification Society grades are divided into The four grades are A, B, D, and E. Due to the strict requirements for shipbuilding plates, alloying elements, Nb, V, and Ti are added to the steel, combined with the production process of the steel plates, to ensure the mechanical properties of high-strength ship plates. Improve the toughness of steel.
2. Introduction to performance indicators of AH36 steel plate AH36 steel plate itself has high strength, high toughness, fatigue resistance, impact resistance, wear resistance, corrosion resistance, weather resistance, acid resistance, welding and easy processing properties. 3. Introduction to the uses of AH36 steel plate AH36 steel plates are often used in the marine engineering manufacturing industry, such as shipbuilding, marine engineering, offshore platform construction, cross-sea bridge leg piles, pillars, and derricks. AH36 steel plate has a variety of high-quality properties, and its high-quality performance during use has also been loved and recognized by the manufacturing industry. Later, due to social recognition, frequent use in the manufacturing industry and continuous optimization and upgrading of manufacturers, gradually AH36 steel plate has also become one of the commonly used steel plate grades in China. AH36, H represents high strength, 36 represents 360MPa, A represents the grade of steel, which can be divided into 4 grades (A, B, D, E). This meaning represents high-strength Class A marine steel with an allowable pressure of 360MPa. AH32 is high-strength A-grade marine steel with a required pressure of 320MPa. There is a difference between the two, so they cannot be replaced. AH36, H represents high strength and A represents the grade of steel, which can be divided into 4 grades (A, B, D, E). The meaning of this code is high-strength A-grade marine steel with a yield strength of 355Mpa.
4. Introduction to chemical composition and alloy elements of AH36 Alloying element carbon C: 0.15-0.18 Alloying element silicon Si: 0.15-0.50 Alloying element manganese Mn: 1.20-1.45 Alloying element phosphorus P: ≤0.025 Alloying element sulfur S: ≤0.015 Alloying element niobium Nb: 0.015-0.025
