The domestic marine stainless steel industrialization is developing rapidly, and it still needs to continue to rise

"In recent years, with the rapid development of China's shipbuilding industry, orders for liquid cargo ships (including chemical tankers and LNG ships, etc.) have surged, and the demand for stainless steel materials has increased significantly, which has promoted the acceleration of the industrialization of China's marine stainless steel products." August On the 14th, Tan Naifen, Deputy Secretary-General and Director of the Statistical Information Department of China Shipbuilding Industry Association, introduced the application and development status of China’s marine stainless steel at the Stainless Steel Online Lecture and Last Online Metal Week hosted by the Stainless Steel Branch of the China Special Steel Enterprise Association. Forecast and prospect the future demand of China's marine stainless steel.

As we all know, the stainless steel ship is one of the ship types with high technical content and high added value recognized by the world shipbuilding industry. Due to its unique advantages such as excellent corrosion resistance, good mechanical properties, and good toughness in ultra-low temperature environments, it can be used in extreme service environments such as different media and different temperatures. Since the 21st century, China’s shipbuilding industry has made breakthroughs and improvements in shipbuilding technology and level. Various duplex stainless steel chemical tankers, liquefied natural gas tankers, and giant tankers (VLCC) containing cutting-edge manufacturing technologies have been built and launched one after another, accelerating China The "climbing" pace of the shipbuilding industry in cutting-edge fields has also created a new situation for the high-quality development of China's shipbuilding industry.

"At present, chemical tankers are still an important growth point for the demand for marine stainless steel." Tan Naifen said that with the rapid development of the petrochemical industry, the liquid cargo seaborne trade will remain active and the demand for chemical tankers will remain relatively stable. growth of. At present, the chemical tanker construction market is developing in the direction of large-scale and multi-liquid cargo tanks with the development of materials and the improvement of construction technology. "However, because it is difficult to form stable mass transportation of a single type of chemical cargo, the large-scale trend of chemical tankers is greatly restricted. In the future, 30,000 to 50,000 dwt chemical tankers will still be the mainstream construction of the market." Tan Naifen specifically pointed out.
