研制了三种类型(Maviwed的可焊耐海水腐蚀钢:MaviwelH50为含Cu、Ni和Mo的50公斤/毫米~2级的低合金钢,在飞溅区具有优良的耐蚀性;MariwelK为含Cr和Mo的一种41或50公斤/毫米~2级的低合金钢,在海水中具有优良的耐蚀性;以及MariwelR为一种含Cr、Cu和Ni的4l或50公斤/毫米~2级的低合金钢,其在飞溅区和海水中均具有优良的耐蚀性。对于工业性生严的钢板的试验结果表明:上述这些钢具有优良的力学性能,可焊性以及极好的耐海水腐蚀性,并比一般钢如SM50B约高二倍的耐蚀性。
Three types of Maviwed solderable seawater resistant steels have been developed: Maviwel H50 is a low alloyed steel of 50 kg / mm ~ 2 containing Cu, Ni and Mo with excellent corrosion resistance in the splash zone; Mariwel K is a Cr And Mo, a low-alloy steel of 41 or 50 kg / mm ~ 2, having excellent corrosion resistance in seawater; and Mariwel R, a 4l or 50 kg / mm ~ 2 grade of Cr, Cu and Ni Of low-alloy steel, which has excellent corrosion resistance in the splash zone and seawater test results for industrial steel sheets show that these steel has excellent mechanical properties, weldability and excellent seawater resistance Corrosive, and about twice as fast as conventional steels such as SM50B.
