1·Corrosion is an electro-chemical process by which a metal such as mild steel ,returns to its natural state ,state ,such as iron oxide or rust.
上面的译文便犯了定义过宽的错误。 试译：腐蚀是金属（如低碳钢）返回其天然状态（如氧化铁即铁锈）的电化学过程。
2·Ferrite and carbon constitute the mild steel.
铁素体和碳组成低碳钢。
3·Stainless steel has a greater elastic springback than mild steel.
不锈钢的弹性反冲比低碳钢要强。
4·Mild steel has a high tensile strength, this being 200 times that of concrete.
低碳钢具有很高的抗拉强度，大约是混凝土的抗拉强度的200倍。
5·The deformation and fracture of mild steel under high frequency bending fatigue has been studied by optical microscope, scanning electron microscope and microhardness determination.
用光学、扫描电子显微镜及显微硬度计，研究了低碳钢在高频弯曲疲劳过程中的形变及断裂。
1·Mild steel is the natural choice for a stove chassis, but such stoves do not last for more than a few weeks in the field.
软钢是炉具底盘的天然选择，但是这种炉子在野外无法熬过几个星期。
2·Mild steel welding is used in SC - 11, bulges, boiler tube with dc welding etc.
