它们真的需要把产品交给中国去加工，例如，当他们有聪明的机器零工资不停地工作的时候？

Do they really need to outsource production to China , for example , when they have clever machines that work ceaselessly without pay ?

实际应用中，许多机器零（部）件要求材料表面耐磨而内部具有良好韧性，如果单纯在高锰钢中加入强化相合金元素制成均质耐磨材料，在提高材料硬度的同时往往会降低材料的韧性。

Although many machine parts require good surface wear resistance and good internal toughness , homogeneous wear resistant material by adding strengthening phase alloy elements to high manganese steel has higher hardness and less toughness at the same time .
