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" simply and clearly indicates the yield strength of the steel plate. AH32 marine steel plate has good impact resistance and machinability, and corrosion resistance.
chemical composition:
Carbon: 018;
Silicon: 0.10—0.50;
Manganese: 0.70—1.60;
Sulfur: 0.40;
P phosphorus: 0.04;
Al aluminum: 0.015;
Nb niobium: 0.015—0.050;
V vanadium: 0.030—0.10;
The delivery status of AH32 ship plate is annealing, hot rolling, normalizing, controlled rolling, TM (different thickness, different delivery status).
AH32 steel plate use
AH32 steel plate is mainly used in the manufacture of hulls, ships and marine engineering, decks, etc. of oceangoing, coastal and inland waterway ships.
The working environment of the ship is harsh, and the hull shell has to withstand the chemical corrosion of seawater, electrochemical corrosion, and the corrosion of marine organisms and microorganisms; it also has to withstand large wind and wave impacts and alternating loads; coupled with complex ship processing and molding, etc., so There are strict requirements on steel for hull structure. AH32 steel plate can meet the requirements very well.
