1）45號(hào)鋼便宜，加工性能好，但耐磨耐腐蝕性能差，浙江槽型螺絲。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(duì)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，浙江槽型螺絲，浙江槽型螺絲，該材料抗氧化耐腐蝕性能高，熱處理hra55`60.建筑結(jié)構(gòu)的主構(gòu)件的螺栓連接。浙江槽型螺絲</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">螺栓在日常生活當(dāng)中和工業(yè)生產(chǎn)制造當(dāng)中，是少不了的，螺栓也被稱為工業(yè)之米。可見螺栓的運(yùn)用之普遍。螺栓的運(yùn)用范圍有：電子產(chǎn)品，機(jī)械產(chǎn)品，數(shù)碼產(chǎn)品，電力設(shè)備，機(jī)電機(jī)械產(chǎn)品。船舶，車輛，水利工程，甚至化學(xué)實(shí)驗(yàn)上也有用到螺栓。反正是超多地方都有用到螺栓的。特如數(shù)碼產(chǎn)品上面用到的精密螺栓。受力方式：普通的和有鉸制孔用的。普通的主要承載軸向的受力，也可以承載要求不高的橫向受力。鉸制孔用的螺栓要和孔的尺寸配合，用在受橫向力時(shí)。</p><p style="text-indent:25px">螺柱:沒有頭部的,*有兩端均外帶螺紋的一類緊固件。連接時(shí),它的一端必須旋入帶有內(nèi)螺紋孔的零件中,另一端穿過帶有通孔的零件中,然后旋上螺母,即使這兩個(gè)零件緊固連接成一見整體。這種連接形式稱為螺柱連接,也是屬于可拆卸連接。主要用于被連接零件之一厚度較大、要求結(jié)構(gòu)緊湊,或因拆卸頻繁,不宜采用螺栓連接的場合。螺釘:也是由頭部和螺桿兩部分構(gòu)成的一類緊固件,按用途可以分為三類:機(jī)器螺釘、緊定螺釘和特殊用途螺釘。機(jī)器螺釘主要用于一個(gè)緊定螺紋孔的零件,與一個(gè)帶有通孔的零件之間的緊固連接,不需要螺母配合(這種連接形式稱為螺釘連接,也屬于可拆卸連接;也可以與螺母配合,用于兩個(gè)帶有通孔的零件之間的緊固連接。)緊定螺釘主要用于固定兩個(gè)零件之間的相對(duì)位置。特殊用途螺釘例如有吊環(huán)螺釘?shù)裙┑跹b零件用。沉頭螺絲又被稱為平機(jī)螺絲。</p><div
