style="font-size:14px;">韌性好。沖擊值與中碳鋼材詳盡，是灰鐵材料的10倍以上。</span> </p> <p> <span style="font-size:14px;">抗腐蝕性強(qiáng)。噴水腐蝕試驗(yàn)，九十天的腐蝕量*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。</span> </p> <p> <span style="font-size:14px;">塑性好。延伸率≥7%，與高碳鋼材相近，而灰鐵材料延伸率為零。</span> </p> <p> <span style="font-size:14px;">強(qiáng)度高?？估瓘?qiáng)度ób≥420MPa,屈服強(qiáng)度ós≥300MPa,與低碳鋼材相同，是灰鐵材料的三倍。</span> </p> <p> <br /> </p> <p> <span style="font-size:14px;">由于球墨鑄鐵的球狀石墨微觀結(jié)構(gòu)，在減弱振動(dòng)能力方面，球墨鑄鐵優(yōu)于鑄鋼，因此更加有利于降低應(yīng)力。選擇球墨鑄鐵的一個(gè)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，也較少了球墨鑄鐵的機(jī)加工成本。</span> </p> <p> <span style="font-size:14px;">球墨鑄鐵的強(qiáng)度和鑄鋼的強(qiáng)度是可比的。球墨鑄鐵具有更高的屈服強(qiáng)度，其屈服強(qiáng)度蕞低為40k，而鑄鋼的屈服強(qiáng)度只有36k。在大部分市政應(yīng)用領(lǐng)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。</span>
