                    球墨鑄鐵井蓋D400.B200代表的是什么意思/

                    韌性好。沖擊值與中碳鋼材相近,是灰鐵材料的10倍以上。

                    Good toughness. The impact value is close to that of medium carbon steel, which is more than 10 times that of gray iron.

                    抗腐蝕性強。噴水腐蝕試驗,九十天的腐蝕量僅為鋼管的1/40,是灰鐵管的1/10。使用壽命是灰鐵管的2倍,是普通鋼管的5倍。

                    Strong corrosion resistance. In the water spray corrosion test, the corrosion amount in 90 days is only 1 / 40 of that of steel pipe and 1 / 10 of that of gray iron pipe. The service life is twice that of gray iron pipe and five times that of ordinary steel pipe.

                    塑性好。延伸率≥7%,與高碳鋼材相近,而灰鐵材料延伸率為零。

                    Good plasticity. Elongation ≥ 7%, similar to that of high carbon steel, while the elongation of gray iron material is zero.

                    強度高??估瓘姸权産≥420MPa,屈服強度ós≥300MPa,與低碳鋼材相同,是灰鐵材料的三倍。

                    QQ截圖20160713182706.png

                    High strength. The tensile strength ó B ≥ 420MPa and the yield strength ó s ≥ 300mpa are the same as those of low-carbon steel, which is three times that of gray iron.

                    由于球墨鑄鐵的球狀石墨微觀結構,在減弱振動能力方面,球墨鑄鐵優于鑄鋼,因此更加有利于降低應力。選擇球墨鑄鐵的一個重要的原因在于球墨鑄鐵比鑄鋼成本低。球墨鑄鐵的低成本使得這種材料更加受歡迎,鑄造效率更高,也減少了球墨鑄鐵的機加工成本。

                    Due to the spheroidal graphite microstructure of nodular cast iron, nodular cast iron is better than cast steel in reducing vibration, so it is more conducive to reducing stress. An important reason for choosing nodular cast iron is that the cost of nodular cast iron is lower than that of cast steel. The low cost of nodular cast iron makes this material more popular, higher casting efficiency, and reduces the machining cost of nodular cast iron.

                    球墨鑄鐵的強度和鑄鋼的強度是可比的。球墨鑄鐵具有更高的屈服強度,其屈服強度為40k,而鑄鋼的屈服強度只有36k。在大部分市政應用領域,如:水、鹽水、蒸汽等,球墨鑄鐵的耐腐蝕性和抗氧化性都超過鑄鋼。

                    The strength of nodular cast iron is comparable to that of cast steel. Ductile iron has higher yield strength, the lowest yield strength is 40K, while the yield strength of cast steel is only 36K. In most municipal applications, such as water, salt water, steam, etc., the corrosion resistance and oxidation resistance of nodular cast iron are better than that of cast steel.

                    井蓋一般分為圓形和方形,在市區的路政方面,一般采用圓形,因為 圓形的井蓋不易傾斜,能夠較好的保護好行人和車輛的安全。

                    Well covers are generally divided into round and square. In terms of urban road administration, round covers are generally used because they are not easy to tilt and can better protect the safety of pedestrians and vehicles.
