style="text-indent:25px">彈簧鋼材有熱軋材、冷拉鋼材、冷軋鋼帶等。彈簧鋼的冶煉是很重要的，必須保證有優(yōu)良的冶金質(zhì)量，不但要保證準(zhǔn)確的化學(xué)成分，而且要有高純凈度，硫、磷、氧、氮等含量要低，鋼質(zhì)均勻性、穩(wěn)定性要好。彈簧鋼的冶金質(zhì)量應(yīng)達(dá)到優(yōu)良鋼、較好的優(yōu)良鋼的水平。彈簧鋼的表面質(zhì)量和尺寸精度對(duì)彈簧的性能和壽命有極大的影響。因?yàn)閺椈射摬慕回洜顟B(tài)的表面除去表面噴丸強(qiáng)化之外不再進(jìn)行加工，因而也就是成品彈簧的工作表面，原有表面上的各種缺陷也留給了彈簧。所以彈簧鋼材表面要求極高，對(duì)脫碳、裂紋、折疊、結(jié)疤、夾雜、分層等限制極嚴(yán)。各種表面缺陷會(huì)使彈簧早期破壞、縮短壽命。以圓截面的鋼絲為例，成品彈簧的強(qiáng)度和剛度分別與鋼絲直徑的三次方和四次方成正比，鋼絲直徑的微小變化會(huì)導(dǎo)致彈簧性能的巨大的波動(dòng)，所以要嚴(yán)格控制鋼材的外形和尺寸公差。這樣，彈簧鋼的加工變形（熱軋、冷軋、冷拔等）就十分重要了，必須極認(rèn)真地對(duì)待。大彈簧預(yù)訂</p></p><br
