class="khcont">20#和45#鋼的c、Si、Mn、P、S含量不同，45要高于20#鋼，你可以買本鋼材只是手冊看一下。20#鋼淬透性、淬硬性低、塑性、韌性、焊接性好，熱軋或正火后韌性更好，可制作不太重要的中、小型滲碳、碳氮共滲件、鍛壓件，如杠桿軸、變速箱變速叉、齒輪，重型機械拉桿、鉤環(huán)等。45#鋼是常用中碳調(diào)質(zhì)鋼，綜合力學性能良好，淬透性低，水淬時易生裂紋。小型件宜采用調(diào)質(zhì)處理，大型件宜采用正火處理，主要用于制造強度高的運動件，如透平機葉輪、壓縮機活塞。軸、齒輪、齒條、蝸桿等。它們通常適用無縫鋼管的材質(zhì)，無縫鋼管又分為GB816GB8163這兩個常用的，但45#鋼只有GB8162才有，45#是機械加工的一種常用鋼管材質(zhì)。普通冷拔無縫鋼管與精軋無縫鋼管的區(qū)別在于普通無縫鋼管主要特點是無焊接縫，可承受較大的壓力。產(chǎn)品可以是很粗糙的鑄態(tài)或冷撥件，適合用于機械加工，流體管道。精密鋼管是近幾年出現(xiàn)的產(chǎn)品，主要是內(nèi)孔、外壁尺寸有嚴格的公差及粗糙度，外表光亮，但的一個缺點是不可以握彎，解決方法后退火但是退火后就不會發(fā)光了但是壁厚公差還可以保證。

class="khcont">無縫化鋼管依據(jù)成型方式不同分為無縫鋼管、焊接鋼管和熱擴管等幾類。無縫鋼管執(zhí)行標準為《低中壓輸送流體用無縫鋼管》(GB/T8163-1999)，是指利用柱狀鋼坯加熱，模具穿孔方式生產(chǎn)的熱軋鋼管和利用冷拔機組將原管拉伸方式生產(chǎn)的冷拔鋼管。該類鋼管特點為管徑大、直度好、壁厚大、產(chǎn)量低、耗能大、成本高、長度10米左右且非定尺，另外一個重要特征是所有鋼管均有偏壁現(xiàn)象，即壁厚不均勻,偏差較大。焊接鋼管目前根據(jù)焊縫形式不同分為直縫焊接鋼管、螺旋焊接鋼管兩種，直縫焊接鋼管就焊接工藝不同又分為直縫電阻焊鋼管（ERW）和直縫埋弧焊鋼管（LSAW），執(zhí)行標準為《低壓流體輸送用焊接鋼管》(GB/T3091-2001)，焊接鋼管均是利用軋輥等模具將帶鋼延圓形漸開線逐步卷為圓形，再通過埋弧、電阻等不同焊接方式焊接成型生產(chǎn)的鋼管。該成型方式的特點是產(chǎn)品產(chǎn)量高、成本低、耗能小、長度可以達16米且可以定尺、直徑及壁厚可良好控制，缺點主要是目前國內(nèi)鋼管生產(chǎn)設(shè)備技術(shù)落后，導致焊縫部分強度不足，壁厚一般國內(nèi)無法做厚。</div><p><img
