With the development of the world economy in the 21st century, the comprehensive national strength of all countries has been significantly improved, and more and more attention has been paid to the development of the ocean. As a result, with the development of navigation industry, ship accessories companies are rising. But do you know the materials for making these accessories? Today, Xiaobian will introduce the principle of material selection for one of the ship accessories, marine door and window covers.

First of all, the materials selected for marine door and window covers should have higher specific strength and specific modulus. Secondly, it is necessary to have excellent welding performance. Because the ship mainly adopts the automatic argon arc welding method, having good weldability means that the tendency of crack formation in welding is also small, in other words, the material selection should have good welding crack resistance. In addition, under the condition of shipbuilding, it is not allowed to recover the lost welding performance of materials by means of RE heat treatment.

Finally, the material selection of marine door and window covers should have excellent corrosion resistance. Because the ship should be used in the sea water medium and marine environment with severe environmental conditions, the corrosion resistance of material selection is essential. If the material is selected properly, it can not only reduce the weight of the ship, but also save energy consumption and increase the carrying capacity of the ship. At the same time, high-quality materials can also reduce the cost of oiling and increase the service life of accessories.

The above is the material selection principle of marine door and window covers that I will introduce to you. I think you have already understood. If you want to choose ship accessories, please choose Nanjing Jingyun ship accessories Co., Ltd. our products are
