2）40Cr的性能優(yōu)于45號鋼，但往往要鍍上一層鉻，以提高其耐腐蝕耐磨損的能力。但對鍍鉻層要求較高，鍍層太薄易于磨損，太厚則易剝落，剝落后反而加速腐蝕，已較少應(yīng)用。熱處理：調(diào)質(zhì)HB220—270，鍍硬鉻HRC>553）氮化鋼、38CrMoAl綜合性能比較優(yōu)異，應(yīng)用比較普遍。一般氮化層達(dá)0．4—0．6毫米。但這種材料抵抗氯化氫腐蝕的能力低，且價(jià)格較高。 3）高溫合金材料優(yōu)于其它材料，該材料不用鍍層，主要用于注塑機(jī)生無鹵螺桿，該材料抗氧化耐腐蝕性能高，熱處理hra55`60.固定螺釘報(bào)價(jià)螺栓M表示“公制，米制”螺紋。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
