What is the difference between D36 and DH36? D36 and DH36 are just different marking methods of bai's classification societies, and they are both high-strength marine steels. D36 is the American standard, and DH36 is the international standard. Shipboard steel plates refer to hot-rolled steel plates produced in accordance with the requirements of the classification society construction rules for the manufacture of hull structures. Due to the harsh working environment of ships, the hull of the hull is subject to seawater chemical corrosion, electrochemical corrosion, marine organisms, and microorganisms.
The hardness of the steel plate is very high, so special equipment is needed to complete the processing and cutting of these materials, dh36 material. In order to cut the plate into an ideal size, the steel plate cutting needs to use natural gas flame for preheating, which will generate a large amount of oxygen flow during the operation. These substances will oxidize the steel plate, and then form a cutting edge, then the cutting operation process is basically completed. In the actual processing work, there are many different classifications for steel plate cutting.
The alloy steel plate is required to obtain a thicker hardened layer, or the dh36 material steel parts with higher strength, hardness, plasticity and toughness. Moreover, the cooling rate of alloy steel during quenching is slower than that of carbon steel, and it is not easy to deform and crack, which is extremely favorable for parts with complex shape or small deformation.
Iron and steel goods, including pig iron, ingots, all kinds of steel and so on. Therefore, logistics companies are required to load evenly and evenly in the process of transportation, prevent moisture and prevent corrosion. It is necessary to prevent the dh36 material steel sheet from being mixed with water when transporting the steel; it is necessary to prevent the dh36 material steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when transporting the steel; it is necessary to prevent the steel from being mixed with water when loading the dh36 material steel sheet on the truck Good luck.
