How about the corrosion resistance of ABS grade A marine steel plate?

ABS Grade A steel is a kind of steel commonly used in the shipbuilding industry. It belongs to the steel grade classification developed by American Bureau of Shipping (ABS). With excellent corrosion resistance, high strength, good fatigue strength, good toughness and better weldability, it is suitable for wide range of applications in the shipbuilding industry. Advantages of ABS Grade A marine steel plates in terms of corrosion resistance include good resistance to atmospheric corrosion, greater resistance to pitting, crevice and stress corrosion cracking, improved weldability, excellent ductility and machinability, and good tensile strength. This corrosion resistance is mainly attributed to the combination of key alloying elements as mentioned earlier. These elements combine to form a protective oxide film on the surface of ABS Grade A steel plates that acts as a barrier to corrosive agents.

ABS
Grade		ABS A	ABS B	ABS D	ABS E
Chemical Composition % ≤	C	0.21	0.21	0.21	0.18
	Mn(≥)	2.5*C	0.80	0.60	0.70
	P	0.035	0.035	0.035	0.035
	S	0.035	0.035	0.035	0.035
	Si	0.50	0.35	0.10-0.35	0.10-0.35

Due to its superior corrosion resistance, ABS Grade A hull steel is highly preferred for shipbuilding applications. It is used for the deck structure, side structure, fairwater lines, mooring systems and even for the rudder. In addition, it is also used to strengthen the overall structure of the ship and to protect its hull from corrosion. Moreover, its excellent impact strength makes it suitable for the more demanding side and bottom plates, thus providing greater life-cycle costs. It offers superior protection against pitting, crevice and stress corrosion cracking, and its weldability, ductility, machinability and tensile strength are all advantageous. Its rustproof design also ensures a longer lifespan and excellent performance in the marine industry.
