1）45號(hào)鋼便宜，加工性能好，但耐磨耐腐蝕性能差。熱處理：調(diào)質(zhì)HB220—270，高頻淬火HRC45--48。 2）40Cr的性能優(yōu)于45號(hào)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.</p><p

style="text-indent:25px">螺栓為什么要兩端倒角呢？倒角是機(jī)械工程上的術(shù)語.比如說在一塊木板上鉆眼,完成后孔壁和板面為90度直角。倒角就是在那個(gè)90度的棱上面再弄一個(gè)一般為45度的小平面,這樣這個(gè)平面和內(nèi)壁,或者和板面之間就都是45度了。這樣做的好處是使在向孔里插東西的時(shí)候不至于被卡住,更方便些。那么螺栓為什么要兩端倒角呢，好處是什么。下面小編要為大家介紹一下了。一、螺栓兩端倒完角以后可以去掉刻料時(shí)的翹角，在一定程度上可以降低螺栓與螺母鏈接時(shí)更順暢的擰入到螺栓里，尤其是細(xì)扣螺栓必須要兩端倒角。二、螺栓倒角以后外觀上更好更精致，深受客戶的歡迎。河南螺釘求購</p><p
