Notch Ductile Steel 耐冲击钢 ; 缺口延性钢
ductile steel beam-to-column connection 韧性钢骨梁柱接头
Ductile Bronze Carbon Steel 球墨铸铁或碳钢
ductile low alloy steel target 延性低合金钢靶
Thus Ductile iron valves can easily replace cast iron or steel valves.
因此球墨铸铁阀门能够方便的替换铸铁或钢阀门。
In next phases, a ductile iron pipes factory with the production capacity of 2 hundred-thousand tons and a steel factory with the production capacity of 2.5 million tones per annum will be added.
在下一阶段，将继续建成一个年产20万吨的球磨铸管厂和年产250万吨的钢厂。
Pump cover material with steel ZG230-450 more, can also be used ductile iron, the latter two materials contrast of wear resistance and hardness and heat resistance to be because the former.
泵体、泵盖的材质采用铸钢ZG230-450的较多，也可以采用球墨铸铁材质，两种材质对比后者的耐磨性和硬度以及耐温性要因为前者。
