40公斤/毫米~2级低合金钢是目前我国海洋开发和海军建设中用途较广的钢种。海军部门对部分舰艇进行调查,发现某些受拉伸应力的区域局部腐蚀较为严重。拉伸应力对低合金钢耐局部腐蚀性能的影响,国内还未见有人研究。E·Traverso等在意大利西北部Genoa港的天然海水中对热轧海军钢板在不同方向上(平行或垂直轧制方向)取样,施加拉伸应力,其伸长率为2%、5%
40 kg / mm ~ 2 low-alloy steel is currently China’s marine development and naval construction uses a wide range of steel. The naval department conducted a survey on some of the ships and found that some of the areas subject to tensile stress are more severely corroded. Tensile stress on the low-alloy steel resistance to localized corrosion, no domestic research. E. Traverso and others sampled the hot-rolled naval steel plates in different directions (parallel or perpendicular to the rolling direction) in natural seawater at the port of Genoa in northwestern Italy and applied tensile stress with an elongation of 2% and 5%
