Introduction to AH32 steel plate

AH32 steel plate is a kind of marine steel plate. "A" inside the plate indicates the quality grade of the steel plate, "H" indicates that the steel plate is high-strength steel plate, and "32" simply and clearly indicates the yield strength of the steel plate. AH32 marine steel plate has good impact resistance, machinability and corrosion resistance.

Chemical composition of AH32 ship plate:
C carbon: 018;
Si silicon: 0.10-0.50;
Mn manganese: 0.70-1.60;
S sulfur: 0.40;
P phosphorus: 0.04;
Al aluminum: 0.015;
Nb niobium: 0.015-0.050;
V vanadium: 0.030-0.10;

AH32 steel plate executive standard: At present, it has passed the certification of the classification society of nine countries, so it is subject to the classification society of nine countries.

Basic mechanical properties of AH32 steel plate:
ReL(MPa)≥315
Rm(MPa) 440-570

AH32 ship plate delivery status: annealing, hot rolling, normalizing, controlled rolling, TM (different thickness, different delivery status)

AH32 steel plate use:
It is mainly used to manufacture the hull, ship, marine engineering and deck of oceangoing, coastal and inland navigation ships. The working environment of the ship is harsh, and the hull shell must withstand the chemical corrosion, electrochemical corrosion and the corrosion of marine organisms and microorganisms; It also has to bear the impact of large wind waves and alternating loads; In addition, due to the complexity of ship processing and molding, the requirements for steel for hull structure are strict.
