易切削钢(freecuttingsteel)在钢中加入一定数量的一种或一种以上的硫、磷、铅、钙、硒、碲等易切削元素，以改善其切削性的合金钢。又称自动机床加工用钢，简称自动钢。这类钢可以用较高的切削速度和较大的切削深度进行切削加工。由于钢中加入的易切削元素，使钢的切削抗力减小，同时易切削元素本身的特性和所形成的化合物起润滑切削刀具的作用，易断屑，减轻了磨损，从而降低了工件的表面粗糙度，提高了刀具寿命和生产效率。易车铁钢材特性：1.易车铁加工性能好：产品具有切削流畅，材质优良，加工稳定，金相***好，化学成份稳定、偏差小，钢质纯度净，不易损伤刀具等特点；极容易在车床切削，刀具使用寿命和生产效率均提高40%；2.电镀性能好：切削加工非常容易；可钻深孔、铣深槽等；加工效率比普钢可大幅提高；产品的电镀性能好，能替代铜制品，大大降低产品成本。易切削钢：Y12Y12PbY15Y15PbY20Y30Y35Y40MnY45CaU71122U72122U71152U72152U70202U70302U70352L20409U73452法：11***n3011***nPb3011***n3711***nPb3710S2010SPb2015***n1335S2035SPb2036***n1436***nPb1438***n2838***nPb2844***n2844SNMnPb2846S2046SPb20德15S1010S2010SPb2015S2215S2035S2035SPb2046S2045S2046SPb2060S2060S2260SPb2211***n309***n2811***nPb309***nPB2811***n379***n3611***nPb379***nPb361.07101.07211.07221.07231.07261.07561.07271.07571.07281.07581.07151.07181.07361.0737国9S2011***n2811***nPb2812***n3512***nPb3510S2010SPb2017***n2035S2035***n2044***n2846S209S20日SUM21SUM22SUM22LSUM23SUM23LSUM24LSUM25SUM31SUM31LSUM32SUM41SUM42SUM43韩SUM11SUM12SUM21SUM22SUM22LSUM23SUM23LSUM24LSUM25SUM31SUM31LSUM32SUM41SUM42SUM43瑞1912191419221926194019571973SS1912SS1914SS1922SS1926SS1940SS1957SS1973英130M15212M36214M15216M44210A15210M15214A15214M1511***n3011***nPb3011***n3711***nPb3710S2010SPb2015***n1335S2035SPb2035SPb2036***n1436***nPb1438***n2838***nPb2844***n2844***nPb2846S2046SPb20美国11081109111011161117111811191132113711391114011411144114511461151121112121213121512L1312L1412L15G11080G11090G11100G11160G11170G11180G111190G11320G11370G11380G11400G11410G11440G11450G11460G11510G12110G12120G12130G12150G12134)
