Ductile Iron vs Steel


Ductile Iron vs Steel

Ductile iron & Steel both are metal alloy. Ductile iron has low weldability as compared to that of steel. One of the main differences between Ductile Iron Vs Steel is that ductile iron has a carbon content of 3.0%-3.9% and steel has a carbon content of 0.08%-0.60%. What this really means is that, ductile iron has a carbon content that is greater than that of steel. Ductile iron vs steel pipe, for a similar pressure design, the wall thickness of a ductile iron pipe will be greater than that of the wall thickness for a steel pipe. The steel pipe can in fact be around 35% thinner than the ductile iron pipe. In understanding ductile iron vs carbon steel valves and ductile iron vs carbon steel corrosion, it is vital to note that ductile iron has superb yield strength, tensile strength and corrosion resistance, but such is not so with carbon steel valves.

Understanding ductile iron vs mild steel, ductile iron was originally built for use in gas industry applications, however, it is also used in the water industry. But mild steel pipe is mainly used in aboveground water systems. Comparing ductile iron vs stainless steel, the damping qualities that are present in ductile iron, are not present in stainless steel. How to tell the difference between ductile iron and steel pipe is very easy, pipes that are made from ductile iron, are stiffer and they have thicker pipe walls, as compared to steel pipes. Between Ductile Iron Vs Steel, there is not much of a difference in the Tensile Strength, but when it comes to Yield Strength, the Yield Strength of ductile iron is greater than that of steel. The Yield Strength of ductile iron is 40 ksi and that of steel is 36 ksi.
