等温淬火能提高碳钢的耐磨性。y_(12)钢在280—400℃等温处理(硬度HB388—415)的耐磨性比淬火回火的同样y_(12)钢(硬度HRc61)的相对耐磨性高20％,比相近硬度的淬火一回火y_(12)钢(硬度为HB429)的相对耐磨性高40％[1]。不同碳含量(C=0.5～1.36％)
Isothermal quenching can improve the wear resistance of carbon steel. The wear resistance of steel y_ (12) at 280-400 ℃ (hardness HB388-415) is 20% higher than that of the same y_ (12) steel (hardness HRc61) after quenching and tempering, Quenching a fire y_ (12) steel (hardness HB429) 40% higher relative wear resistance [1]. Different carbon content (C = 0.5 ~ 1.36%)
