求翻译：調整合金元素的量，及其存在與鋼中的形式，就能夠控制鋼成品的特性，例如硬度、延展性及強度。加了碳的鋼會比純鐵更硬更強，但是這種鋼的延展性會比鐵差。是什么意思？

Adjust alloy elements of volume, and their presence and steel in the form, you will be able to control steel parts of characteristics, such as area, scalability and strength. The carbon steel than plain iron more hard stronger, but this kind of steel scalability than iron deviation.

Adjusts the alloying element the quantity, and in the existence and the steel form, can 夠 control the steel end product the characteristic, for example degree of hardness, ductility and intensity.Added the carbon steel to be able to be harder than the ferrite strongly, but this kind of steel ductili

Adjust the amount of alloying elements, and its forms and steel, you can control the properties of the finished product, such as the hardness, ductility and strength. Add carbon steel is harder and stronger than iron, but the steel ductility is worse than iron.
