KS2是一种新型不锈钢,用作船用螺旋浆材料具有极好的特性。本文是通过试验叶片的试验结果其中包括实船运行试验结果来描述KS2材料特性的。具体特性如下:1)KS2具有良好的铸造性能,可以铸造出没有任何有害缺陷的完好铸件。2)KS2比普通的青铜和其它传统的不锈钢耐海水腐蚀和空泡腐蚀的性能强得多。3)KS2的机械性能比普通的青铜和传统的不锈钢好得多。抗海水腐蚀疲劳能力也较强。4)由于KS2材料有良好的可焊性和成形性,所以KS2叶片易于修理。5)在KS2螺旋浆的实际运行实验中,没有任何损坏的迹象,如空泡腐蚀等。
KS2 is a new type of stainless steel for marine propellants with excellent properties. This article describes the KS2 material properties through the test results of the test blades, including the results of real-world ship operation tests. Specific features are as follows: 1) KS2 has a good casting performance, you can cast without any harmful defects of good castings. 2) KS2 is much stronger than ordinary bronze and other traditional stainless steels in seawater and cavitation corrosion resistance. 3) The mechanical properties of KS2 are much better than those of ordinary bronze and traditional stainless steel. Anti-seawater corrosion fatigue ability is also stronger. 4) KS2 blades are easy to repair due to their good weldability and formability. 5) There is no sign of any damage in the practical operation of KS2 propellants, such as cavitation corrosion.
