QT500球墨鑄鐵的特點(diǎn)是很多人都了解的，但是又不能具體的解說(shuō)，導(dǎo)致了很多人初學(xué)者都不是很清楚。而對(duì)于QT500球墨鑄鐵的價(jià)格也是很多創(chuàng)業(yè)者或者采購(gòu)經(jīng)理想查詢到的，對(duì)于的百度而言總能在上面查到上述的兩條信息，但是，由于了解的人不多，所以關(guān)于這類信息很少。 因此今天借助列表網(wǎng)這個(gè)平臺(tái)為大家介紹一下QT500球墨鑄鐵的特點(diǎn)和QT500球墨鑄鐵的價(jià)格。 QT500球墨鑄鐵的特點(diǎn)：含碳量大于 2% 的鐵碳合金，工業(yè)生鐵含碳量一般在 2.5% ～ 4% ，并含 C 、 SI 、 Mn 、 S 、 P 等元素，對(duì)金屬基體的割裂作用比片狀石墨小，使鑄鐵的強(qiáng)度達(dá)到基體組織強(qiáng)度的 70 ～ 90% ，抗拉強(qiáng)度可達(dá) 120kgf/mm2 ，并且具有良好的韌性。球墨鑄鐵除鐵外的化學(xué)成分通常為：含碳量 3.6 ～ 3.8% ，含硅量 2.0 ～ 3.0% ，含錳、磷、硫總量不超過(guò) 1.5% 和適量的稀土、鎂等球化劑。 Characteristics of QT500 ductile cast iron is a lot of people know, but not detailed explanation, leading to a lot of people are not very clear for beginners. But for QT500 nodular cast iron is the price of many entrepreneurs or purchase the ideal query, for everything Baidu always to check two pieces of information, the above but, because not a lot of people know about these little information, so. So today use this platform to list to introduce the characteristics of QT500 and QT500 ductile cast iron ductile iron price. Characteristics of QT500 nodular cast iron: iron carbon alloys containing carbon content of more than 2%, pig iron carbon content in general 2.5% ~ 4%, and with C, SI, Mn, S, P and other elements, separate effect on metal matrix graphite cast iron is small, the strength of matrix strength reached 70 ~ 90%, the tensile strength can reach 120kgf/mm2, and has good toughness. Ductile iron chemical composition in addition to iron usually: carbon content of 3.6 ~ 3.8%, 2 ~ 3% of silicon, manganese, phosphorus, sulfur amount does not exceed 1.5% and the amount of rare earth, magnesium nodulizing agent.
