Synopsis : Three types of weldable seawater corrosion resistant steels, "MARIWEL", have been developed: MARIWEL H50 is a 50kgf/mm2 class low alloy steel containing Cu, Ni and Mo, and has a good corrosion resistance in splash zone; MARIWEL K is a 41 or 50kgf/mm2 class low alloy steel containing Cr and Mo, and has a good corrosion resistance in submerged zone; and MARIWEL R is a 41 or 50kgf/mm2 class low alloy steel containing Cr, Cu and Ni, which shows good corrosion resistance in both splash and submerged zone. The test results for the commercially produced steel plates indicate that these steels have good mechanical properties and weldabilities and well as excellent seawater-corrosion resistance. These steels show about twice corrosion resistance compared with that of ordinary steels such as SM50B. |
