我国海洋用钢进行十年挂片统评试验已取得重要成果,这对研制和发展我国海洋用钢具有极为重要的意义。全世界每年有上亿吨金属材料因受各种腐蚀而损耗,其中,海洋腐蚀约占1/3。在各种海洋设施上已广泛采用保护措施的同时,各图对海洋用钢的研究仍然给予高度重视。1966年,我国石油部门急需采油平台用钢, China’s marine steel ten years coupon evaluation system has made important achievements, which is of great significance for the development and development of China’s marine steel is of great significance. Every year, hundreds of millions of tons of metal materials in the world are depleted due to various kinds of corrosion, of which about one third are marine corrosion. While various protective measures have been widely adopted at various marine facilities, the studies on marine steel still remain highly valued. In 1966, China’s oil sector urgently needed oil platform steel,
