What are the characteristics of ductile iron manhole cover

What are the characteristics of ductile iron manhole coverDuctile iron manhole covers mainly the build out of the covers. This covers on their quality involves the question of the rate of the ball. Casting process is commonly used in anti-rust coating paint the asphalt. Of course, the surface of manhole covers is through asphalt paint spray rust treatment. Manhole covers have an advantage. Ductile iron is due to the high strength and good toughness. So ductile than covers the same type of gray cast iron manhole covers about 30% lighter.


ductile iron manhole cover features:


Good toughness. Impact value and carbon steel exhaustive. Is 10 times more gray iron material.


Corrosion resistance. Spray corrosion test. The amount of corrosion of steel is only ninety days of 1/40, 1/10 gray iron pipe. Life is twice as gray iron pipes. It is five times that of ordinary steel pipe.


Good plasticity. Elongation ≥7%. And similar high-carbon steel. The gray iron material elongation zero.


high strength. Tensile strength ób≥420MPa. Low-carbon steel with a yield strength ós≥300MPa same. Three times as gray iron material.


Since the microstructure of spheroidal graphite ductile iron. Weakening vibration capability. Ductile iron is better than steel. Therefore more conducive to reducing stress. One important reason is that the choice of ductile iron cast ductile lower than cost. Ductile Iron low cost makes this material more popular. Higher casting efficiency. Less ductile iron machining costs.


Strength and intensity of cast ductile iron are comparable. Ductile iron has a higher yield strength. Minimum yield strength of 40k. The yield strength of steel is only 36k. In most municipal applications. Such as: water, salt water, steam and the like. Ductile iron corrosion resistance and oxidation resistance than steel.
