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(dòng)機(jī)床加工用鋼，簡(jiǎn)稱自動(dòng)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(shí)易切削元素本身的特性和所形成的化合物起潤(rùn)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(hào)化學(xué)成分（%）CSiMnPSPb低碳快削鋼GB國(guó)家標(biāo)準(zhǔn)
