碳素钢是海洋工程中应用最多的金属。尽管近年来高强度低合金钢的应用不断增加,铸铁也在一些专门场合扩大了其应用,但海洋工程中碳钢的应用仍居首位。这是因为碳钢成本低,易加工,物理性能良好,加之多年来长期沿用,积累了一定设计经验的缘故。在海洋性气体层下影响碳钢受蚀程度的首要因素是其所处暴露环境。海风的侵袭和碎浪的冲击,冲击愈烈材料受腐蚀程度愈高。 Carbon steel is the most widely used metal in marine engineering. Despite the increasing use of high-strength, low-alloy steels in recent years, cast iron has also expanded its use on a number of specialized occasions, but the use of carbon steels in marine engineering still ranks first. This is because carbon steel low cost, easy processing, good physical properties, coupled with long-term use over the years, has accumulated some design experience. The main factor that affects the corrosion of carbon steel under the layer of marine gas is its exposed environment. The impact of the sea breeze and the impact of broken waves, the more intense the impact of corrosion by the higher the material.
