It is indicated by analysis that the main causes of difficulty of drawing high strength thick galvanized steel wire are thicker ZnFe alloy coat and higher carbon and manganese contents.
分析大直径高强度镀锌钢丝拉拔困难的主要原因在于锌-铁合金层较厚、钢丝中碳含量和锰含量较高。

Under lower and medium impact energy, the abrasive wear resistant performance of the steel metioned is higher than that of low alloyed medium carbon wear resistant steel and highmanganese cast steel.
结果表明，在中、低冲击磨料磨损条件下，试验钢的耐磨性优于中碳低合金耐磨钢和高锰钢。

Wear loss of specimens for these two steels during a certain time show that low carbonhigh alloy steel is much more resistant to corrosive impact abrasion than high manganese steel.
