What is the difference between marine steel plate AH36 and DH36? AH36 steel is normal temperature steel, and DH36 steel is low temperature steel. Shipboard steel plates refer to hot-rolled steel plates produced in accordance with the requirements of classification societies for the manufacture of hull structures. In order to ensure quality and ensure sufficient toughness, the chemical composition of Mn/C is required to be above 2.5.
Nickel element is mainly used to form and stabilize the austenite structure, so that the RINA FH32 ship hulls steel plates steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
