DH36 steel plate is easily corroded by seawater in the marine environment, so measures need to be taken for corrosion protection. Commonly used anti-corrosion measures of DH36 steel plate are as follows:
1. Spray coating
Spraying a layer of anti-corrosion coating on the surface of the DH36 steel plate can effectively prevent the DH36 steel plate from being corroded by seawater. Commonly used spray coatings include epoxy resin coatings, polyurethane coatings, and fluorocarbon coatings.
2. Galvanized
The DH36 steel plate is soaked in the molten zinc liquid, so that a layer of zinc layer is formed on the surface of the DH36 steel plate. The galvanized DH36 steel plate performs better in harsh environments such as storms and waves.
3. Electrodeposition
Electrodeposition is to immerse the DH36 steel plate in an electrolytic cell containing metal ions, and undergo electrode polarization treatment, so that the metal ions are deposited on the surface of the DH36 steel plate to form a layer of metal coating, which can effectively prevent the DH36 steel plate from being corroded. Commonly used electrodeposited metals are zinc, aluminum, copper, etc. ,
4. Alloying
A certain amount of alloying elements are added during the preparation of the DH36 steel plate. Commonly used alloying elements include chromium, molybdenum, titanium, copper, etc. Adding a certain amount of alloying elements can not only improve the corrosion resistance of DH36 steel plate, but also improve the mechanical properties and heat treatment performance of DH36 steel plate.
To sum up, it is very necessary to optimize the whole process and corrosion protection of DH36 steel plate. If you need to buy DH36 steel plate, please feel free to contact BBN!
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
