What's the difference between AH36 and DH36 shipping steel plates?

DH36 material

AH36 material is a kind of normal temperature steel, and DH36 steel is a kind of low temperature steel.
Shipping steel plate, manufactured in regard of classification society, is widely used in building ship structure. Because of its poor working conditions, hull shell is easy to suffer from chemical corrosion, electrochemical corrosion, marine organism and microorganism. Besides, it can bear high impact of stormy waves and stress alternation. What's more, complex manufacture method is another vital factor to affect this kind of material steel. Because of its above factors, it is strict to choose better toughness to produce these shipping steel plates. In addition, high strength, good corrosion resistance, welding property, processing forming performance and surface quality play an important role in manufacturing this kind of material. In order to ensure excellent quality and enough toughness, Mn/C chemical content is required above 2.5, and produced from mill recognized ship department.
Shipping steel plates can divided into two levels according to min yield strength, ordinary strength and high strength. There are such four grade as A,B,D ,E about ordinary shipping steel plates. And high strength steel plates are including AH32、DH32、EH32、AH36、DH36、EH36.
