铸钢跟铸铁有什么区别
一、性质不同
1、铸钢:指专用于制造钢质铸件的钢材。
2、铸铁:主要由铁、碳和硅组成的合金的总称。
二、特点不同
1、铸钢:更大的设计灵活性;冶金制造最强的灵活性和可变性;提高整体结构强度;大范围的重量变化;钢铸件的吸振性、耐磨性和机动性不如铁铸件。
2、铸铁:含碳量较高的铁,质脆,不能锻压。
三、用途不同
1、铸钢:铸钢可以依其化学成分分为铸造合金钢和铸造碳钢,也可以依其使用特性分为铸造工具钢、铸造特殊钢、工程与结构用铸造和铸造合金钢等。
2、铸铁:由于退火周期长,工艺复杂,成本高,只适 用于大批量生产薄壁零件。

铸钢和碳钢材质有什么不同
铸钢和碳钢的区别:
1、性质不同
铸钢:铸钢是铸造合金的一种,以铁、碳为主要元素,含碳量在0-2%之间。
碳钢:碳钢是含碳量在0.0218%~2.11%的铁碳合金,一般还含有少量的硅、锰、硫、磷。
2、特点不同
铸钢:304、316铸钢是目前应用最为广泛的不锈钢,两者皆是奥氏体铸钢,无磁性或弱磁性。而430、403、410 是奥氏体-铁素体不锈钢,有磁性。
碳钢:一般碳钢中含碳量较高则硬度越大,强度也越高,但塑性较低。
3、分类不同
铸钢:按使用特性分为:铸造工具钢。铸造工具钢又可以分为铸造刀具钢和铸造模具钢;铸造特殊钢。铸造特殊钢可以分为铸造不锈钢、铸造耐热钢、铸造耐磨钢、铸造镍基合金等;
工程与结构用铸钢。工程与结构用铸钢可以分为铸造碳素结构钢和铸造合金结构钢;铸造合金钢。其可以分为铸造低合金钢、铸造中合金钢和铸造高合金钢。
碳钢:按用途可以把碳钢分为碳素结构钢、碳素工具钢和易切削结构钢三类,碳素结构钢又分为工程构建钢和机器制造结构钢两种。

铸钢是什么?它的种类和特点是什么?
304 316铸钢是目前应用最为广泛的不锈钢
304,C≤0.08 Ni8.00~10.00 Cr18.00~20.00,Mn=2.0
Si=1.0 S=0.030 P=0.035
304LC≤0.03其他的元素与304相同
304 316是奥氏体铸钢,无磁性或者弱磁性,430 403 410 这些是奥氏体-铁素体不锈钢 有磁性。
铸钢是以铁、碳为主要元素的合金,碳含量0-2%。铸钢又分为铸造碳钢、铸造低合金钢和铸造特种钢3类。
①铸造碳钢。以碳为主要合金元素并含有少量其他元素的铸钢。含碳小于0.2%的为铸造低碳钢,含碳0.2%~0.5%的为铸造中碳钢,含碳大于0.5%的为铸造高碳钢。随着含碳量的增加,铸造碳钢的强度增大,硬度提高。铸造碳钢具有较高的强度、塑性和韧性,成本较低,在重型机械中用于制造承受大负荷的零件,如轧钢机机架、水压机底座等;在铁路车辆上用于制造受力大又承受冲击的零件如摇枕、侧架、车轮和车钩等。
②铸造低合金钢。含有锰 、铬、铜等合金元素的铸钢。合金元素总量一般小于5%,具有较大的冲击韧性,并能通过热处理获得更好的机械性能。铸造低合金钢比碳钢具有较优的使用性能,能减小零件质量,提高使用寿命。
③铸造特种钢。为适应特殊需要而炼制的合金铸钢,品种繁多,通常含有一种或多种的高量合金元素,以获得某种特殊性能。例如 ,含锰11%~14%的高锰钢能耐冲击磨损,多用于矿山机械、工程机械的耐磨零件;以铬或铬镍为主要合金元素的各种不锈钢,用于在有腐蚀或650℃以上高温条件下工作的零件,如化工用阀体、泵、容器或大容量电站的汽轮机壳体等。
