球墨鑄鐵、鑄鐵、鑄鋼的區(qū)別？與鑄鐵相比，球墨鑄鐵在強(qiáng)度方面具有的優(yōu)勢(shì)。球墨鑄鐵的抗拉強(qiáng)度是60k，而鑄鐵的抗拉強(qiáng)度只有31k。球墨鑄鐵的屈服強(qiáng)度是40k，而鑄鐵并沒有顯示出屈服強(qiáng)度，并且較終出現(xiàn)斷裂。球墨鑄鐵的強(qiáng)度-成本比遠(yuǎn)遠(yuǎn)優(yōu)于鑄鐵。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)度較低為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。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。作為鋼的替代品，1949年人類開發(fā)了球墨鑄鐵。鑄鋼含碳量少于，而鑄鐵和球墨鑄鐵含炭量量則至少為3%。鑄鋼中的低含碳量使得作為游離石墨存在的碳不會(huì)形成結(jié)構(gòu)薄片。鑄鐵內(nèi)的碳天然形式是游離石墨薄片形式。在球墨鑄鐵內(nèi)，這種石墨薄片通過特殊的處理方法變化成微小的球體。這種改進(jìn)后的球體使得使得球墨鑄鐵比鑄鐵和鋼相比具有更加優(yōu)異的物理性能。正是這種碳的球狀微觀結(jié)構(gòu)。烏魯木齊球墨鑄鐵管哪家好</p><p
