This invention relates to a micro-alloyed martensite wear-resisting casting steel. The steel is composed of (by wt.%): C=0.25-0.34, Si=0.3-0.7, Mn=1.15-1.65, Cr=0.5-1.0, B=0.0005-0.005, Ti=0.01-0.06, Ce=0.01-0.045, La=0.01=0.035, Al=0.01-0.1, S<0.035, P<0.035. The micro-alloyed steel prodn. procedures are as follows: at the temp. of 1600-1610 deg.C, TiFe is fed into the furnace, after that, RESiFe and BFe allyo being added into ladle or simultaneously fed together with pouring molten steel… CONTINUE READING
