45#鋼管批發
無錫興百(bai)優金屬制品有(you)限公司 正品銷售 45#鋼管(guan) 現(xian)貨供應
45#鋼管通常適用無縫鋼管的材質，無縫鋼管又分為GB8162、GB8163這兩個常用的(de)，但45#鋼只有GB8162才有，45#是(shi)機(ji)械(xie)加(jia)工的(de)一種常用材質。
45#鋼管(GB/T14975-2002)是廣泛用于化工、石油(you)、輕紡、醫療、食品、機械等工業的(de)耐腐蝕管道和結構件(jian)及零件(jian)的(de)不銹鋼制(zhi)成(cheng)的(de)熱軋(ya)(擠、擴)和冷拔(軋(ya))。
熱(re)處(chu)(chu)理推薦熱(re)處(chu)(chu)理溫度：正火850，淬火840，回火600.
45號鋼(gang)(gang)為(wei) 優質(zhi)碳(tan)(tan)素結(jie)構用(yong)(yong)(yong)(yong)(yong)(yong)鋼(gang)(gang) ,硬(ying)(ying)度(du)(du)不高(gao)易切削加工,模具中(zhong)常用(yong)(yong)(yong)(yong)(yong)(yong)來做模板,梢子(zi),導柱等(deng),但須熱處(chu)(chu)(chu)理(li)(li) 。 1. 45號鋼(gang)(gang)淬(cui)(cui)(cui)火(huo)(huo)(huo)(huo)后沒(mei)有(you)回火(huo)(huo)(huo)(huo)之(zhi)前，硬(ying)(ying)度(du)(du)大于(yu)HRC55(最(zui)高(gao)可(ke)達HRC62)為(wei)合(he)格。 實際(ji)應用(yong)(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)(de)最(zui)高(gao)硬(ying)(ying)度(du)(du)為(wei)HRC55(高(gao)頻(pin)淬(cui)(cui)(cui)火(huo)(huo)(huo)(huo)HRC58)。 2. 45號鋼(gang)(gang)不要(yao)采用(yong)(yong)(yong)(yong)(yong)(yong)滲(shen)碳(tan)(tan)淬(cui)(cui)(cui)火(huo)(huo)(huo)(huo)的(de)(de)(de)(de)熱處(chu)(chu)(chu)理(li)(li)工藝。 調(diao)(diao)質(zhi)處(chu)(chu)(chu)理(li)(li)后零(ling)件(jian)具有(you)良好的(de)(de)(de)(de)綜(zong)合(he)機械性(xing)(xing)能(neng)，廣泛應用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)各種(zhong)重(zhong)要(yao)的(de)(de)(de)(de)結(jie)構零(ling)件(jian)，特(te)別是(shi)那(nei)些在(zai)交變負荷下工作的(de)(de)(de)(de)連桿(gan)、螺栓、齒輪及(ji)軸類等(deng)。但表(biao)面硬(ying)(ying)度(du)(du)較(jiao)低，不耐磨(mo)。可(ke)用(yong)(yong)(yong)(yong)(yong)(yong)調(diao)(diao)質(zhi)+表(biao)面淬(cui)(cui)(cui)火(huo)(huo)(huo)(huo)提(ti)高(gao)零(ling)件(jian)表(biao)面硬(ying)(ying)度(du)(du)。 滲(shen)碳(tan)(tan)處(chu)(chu)(chu)理(li)(li)一般用(yong)(yong)(yong)(yong)(yong)(yong)于(yu)表(biao)面耐磨(mo)、芯(xin)部(bu)耐沖(chong)(chong)(chong)擊(ji)的(de)(de)(de)(de)重(zhong)載零(ling)件(jian)，其(qi)耐磨(mo)性(xing)(xing)比調(diao)(diao)質(zhi)+表(biao)面淬(cui)(cui)(cui)火(huo)(huo)(huo)(huo)高(gao)。其(qi)表(biao)面含碳(tan)(tan)量0.8--1.2%，芯(xin)部(bu)一般在(zai)0.1--0.25%(特(te)殊情(qing)況下采用(yong)(yong)(yong)(yong)(yong)(yong)0.35%)。經熱處(chu)(chu)(chu)理(li)(li)后，表(biao)面可(ke)以(yi)獲得很高(gao)的(de)(de)(de)(de)硬(ying)(ying)度(du)(du)(HRC58--62)，芯(xin)部(bu)硬(ying)(ying)度(du)(du)低，耐沖(chong)(chong)(chong)擊(ji)。 如果(guo)用(yong)(yong)(yong)(yong)(yong)(yong)45號鋼(gang)(gang)滲(shen)碳(tan)(tan)，淬(cui)(cui)(cui)火(huo)(huo)(huo)(huo)后芯(xin)部(bu)會出現硬(ying)(ying)脆(cui)的(de)(de)(de)(de)馬氏體，失去滲(shen)碳(tan)(tan)處(chu)(chu)(chu)理(li)(li)的(de)(de)(de)(de)優點。現在(zai)采用(yong)(yong)(yong)(yong)(yong)(yong)滲(shen)碳(tan)(tan)工藝的(de)(de)(de)(de)材(cai)料，含碳(tan)(tan)量都(dou)不高(gao)，到(dao)(dao)0.30%芯(xin)部(bu)強(qiang)度(du)(du)已經可(ke)以(yi)達到(dao)(dao)很高(gao)，應用(yong)(yong)(yong)(yong)(yong)(yong)上不多(duo)見(jian)(jian)。0.35%從(cong)來沒(mei)見(jian)(jian)過實例，只在(zai)教科書里有(you)介紹。可(ke)以(yi)采用(yong)(yong)(yong)(yong)(yong)(yong)調(diao)(diao)質(zhi)+高(gao)頻(pin)表(biao)面淬(cui)(cui)(cui)火(huo)(huo)(huo)(huo)的(de)(de)(de)(de)工藝，耐磨(mo)性(xing)(xing)較(jiao)滲(shen)碳(tan)(tan)略差。 GB/T699-1999標(biao)準規定的(de)(de)(de)(de)45鋼(gang)(gang)推薦熱處(chu)(chu)(chu)理(li)(li)制度(du)(du)為(wei)850℃正火(huo)(huo)(huo)(huo)、840℃淬(cui)(cui)(cui)火(huo)(huo)(huo)(huo)、600℃回火(huo)(huo)(huo)(huo)，達到(dao)(dao)的(de)(de)(de)(de)性(xing)(xing)能(neng)為(wei)屈(qu)服(fu)強(qiang)度(du)(du)≥355MPa GB/T699-1999標(biao)準規定45鋼(gang)(gang)抗拉強(qiang)度(du)(du)為(wei)600MPa，屈(qu)服(fu)強(qiang)度(du)(du)為(wei)355MPa，伸長率為(wei)16%，斷面收縮率為(wei)40%，沖(chong)(chong)(chong)擊(ji)功為(wei)39J
