Beschreibung
Zusammenfassung:	The feature of this invention lies on: the content (by weight percentage) of various components are: C 0.35-0.5, Cr 0.8-1.5, Si 0.6-1.2 Mo 0.3-0.5, Mn 0.6-1.4, Cu 0.5-1, No.1 RE 0.01-0.1 the remainder is Fe. The chief characteristic of this invention is that the modification treatment of No.1 RE and increasement of Cu content is carried out simultaneously. Thus, the modification effect of No.1 RE is raised, and effect of fining of crystal grain, purification of crystal boundary is resulted, hardenability and uniformity in texture and performance. The aK is greater than 18 (J/cm to the power 2), HRC is 46-54, the service life is increased by two folds.
