| Abstract: | In order to improve the strength and toughness of blades for rotary lawnmowers,the steel 20 and 20 SiMn were quenched,and the 40Mn was carried out in theaustempering and the subcritical quenching. The results show that the above mentionedmaterials can obtain higher strength and toughness than that of 65Mn in common quenchingand mid temperature tempering or high temperature tempering. |
