AH32 marine steel plate

AH32 steel plate is a kind of marine steel plate. The "A" inside the grade indicates the quality grade of the steel plate, "H" indicates that the steel plate is a high-strength steel plate, and "32" is a concise and clear description of the yield strength of the steel plate.

There are two types of steel for hull structure: general strength steel and high strength steel.
The quality of general strength steel is divided into four grades: A, B, D, and E;
High-strength steel is further divided into two strength levels and three quality levels: AH32, DH32, EH32, AH36, DH36, EH36.

AH32 chemical composition:
Carbon (C)≤0.18 [2]
Manganese (Mn) 0.70～1.60
Aluminum (Al)≥0.015
Silicon (Si) 0.10～0.50
Phosphorus (P)≤0.04
Sulfur (S)≤0.4
Niobium (Nb) 0.015～0.050
Alum (V) 0.030～0.100

AH32 classification society certification:
It has been certified by nine classification societies including ABS in the United States, BV in France, LR in the United Kingdom, GL in Germany, DNV in Norway, RINA in Italy, NK in Japan, CCS in China, and KR in South Korea.

AH32 marine steel plate has good impact resistance and machinability, and good corrosion resistance.

AH32 is a marine steel plate, which is mainly used to manufacture the hull and deck of ocean-going, coastal and inland shipping ships.
