易切削鋼化學(xué)成分表易切削鋼(freecuttingsteel)是在鋼中加入一定數(shù)量的一種或一種以上的硫、磷、鉛、鈣、硒、碲等易切削元素，以改善其切削性的合金鋼，又稱自動機(jī)床加工用鋼，簡稱自動鋼


。這類鋼可以用較高的切削速度和較大的切削深度進(jìn)行切削加工。由于鋼中加入的易切削元素，使鋼的切削抗力減小，同時易切削元素本身的特性和所形成的化合物起潤滑切削刀具的作用，易斷屑，


減輕了磨損，從而降低了工件的表面粗糙度，提高了刀具壽命和生產(chǎn)效率。分類執(zhí)行標(biāo)準(zhǔn)牌號化學(xué)成分（%）CSiMnPSPb低碳快削鋼GB國家標(biāo)準(zhǔn)
