Lockable Cover Carriageway Superiority: 1----Anti-theft: cover and base frame integrate connection, hinge-type opening, sledgehammer hit not break it, completely anti-theft. 2----Load-bearing great: the toughness of ductile iron is fourfold that of ordinary cast iron, close to steel materials, suitable for all kinds of road use! Lockable Frame Carriageway Introduction A. Use: Municipal roads, highways, communications, electricity, water, communities, schools and other parks. B. Merit: The ductile iron manhole cover has an advantage that the spheroidal graphite cast iron cover is about 30% lighter than the same type of gray cast iron manhole cover because of the high strength and toughness of the ductile cast iron. C. Features: Good toughness. The impact value is similar to that of medium carbon steel, which is more than 10 times that of gray iron. D. Strong corrosion resistance. In the water spray corrosion test, the corrosion amount for 90 days is only 1/40 of the steel pipe, which is 1/10 of the gray iron pipe. The service life is twice that of gray iron pipes and five times that of ordinary steel pipes. E. Good plasticity. The elongation is �7%, which is similar to that of high carbon steel, and the elongation of gray iron material is zero. F. high strength. The tensile strength ób � 420 MPa and the yield strength ós � 300 MPa are the same as those of the low carbon steel, which is three times that of the gray iron material. G. Due to the spherical graphite microstructure of ductile iron, ductile iron is superior to cast steel in reducing vibration capacity, so it is more conducive to reducing stress. An important reason for choosing ductile iron is that ductile iron is less expensive than cast steel. The low cost of ductile iron makes this material more popular, casting more efficient, and reduces the machining cost of ductile iron. H. The strength of ductile iron is comparable to the strength of cast steel. Ductile iron has a higher yield strength with a yield strength of at least 40k, while cast steel has a yield strength of only 36k. In most municipal applications, such as water, brine, steam, etc., ductile iron has more corrosion resistance and oxidation resistance than cast steel.
