屈服强度直接影响铸铁井盖的事宜时间

来源:http://www.kpp647.com添加时间:2018-03-02 14:46:39

球墨铸铁井盖篦子的抗拉强度及耐压性能与钢相似,因此又名铸钢。相比传统灰口铸铁其延伸率大大提高,具有良好的韧性,不易破坏,具有比普通铸铁井盖较好的防盗性能,整体性能更大大优于普通铸铁井盖。

Ductile iron manhole grate tensile strength and pressure resistance of steel and similar, so also known as cast steel. Compared with the traditional gray iron, its elongation rate is greatly improved, it has good toughness, and is not easy to destroy. It has better anti-theft performance than ordinary cast iron manhole cover, and the overall performance is much better than that of common cast iron manhole cover.

冲击值与中碳钢材详尽,是灰铁材料的10倍,抗腐蚀性强。喷水腐蚀试验,九十天的腐蚀量仅为钢管的1/40,是灰铁管的1/10。使用寿命是灰铁管的2倍,是普通钢管的5倍。

The impact of value and medium carbon steel in detail, is 10 times the iron material, strong corrosion resistance。 In the water jet corrosion test, the corrosion amount of ninety days is only 1/40 of the steel tube and the 1/10 of the ash iron pipe。 The service life is 2 times that of the gray iron pipe and 5 times that of the ordinary steel pipe。

球墨铸铁的强度和铸钢的强度是可比的,球墨铸铁具有更高的屈服强度,其屈服强度更低为40k,而铸钢的屈服强度只有36k。

The strength of ductile iron is comparable to that of cast steel. Ductile iron has higher yield strength, and its yield strength is lowest 40K, while the yield strength of cast steel is only 36K.

在大部分市政应用领域,如:水、盐水、蒸汽等,球墨铸铁的耐腐蚀性和抗氧化性都超过铸钢,主要应用领域:市政道路,高速公路,通信,电力,自来水,小区,学校等各种园区。

In most municipal applications, such as water, brine and steam, the corrosion resistance and oxidation resistance of ductile iron are all higher than that of cast steel. The main application fields are municipal roads, highways, communications, electric power, tap water, residential quarters, schools and so on.

延伸率≥7%,与高碳钢材相近,而灰铁材料延伸率为零,抗拉强度ób≥420MPa,屈服强度ós≥300MPa,与低碳钢材相同,是灰铁材料的三倍。

The elongation rate is more than 7%, similar to the high carbon steel and iron materials, the elongation is zero, tensile strength, yield strength, B = 420MPa, s = 300MPa, with the same low carbon steel, is three times the iron material。
