不銹(xiu)鋼鍛件的物理性能(neng)

根(gen)據不(bu)(bu)銹(xiu)(xiu)鋼(gang)(gang)(gang)和碳(tan)(tan)鋼(gang)(gang)(gang)的物理性能(neng)數(shu)據，從而(er)(er)可知(zhi)碳(tan)(tan)鋼(gang)(gang)(gang)的密度略高于(yu)鐵素體型(xing)(xing)(xing)(xing)和馬(ma)(ma)氏(shi)(shi)體型(xing)(xing)(xing)(xing)不(bu)(bu)銹(xiu)(xiu)鋼(gang)(gang)(gang)，而(er)(er)略低(di)于(yu)奧氏(shi)(shi)體型(xing)(xing)(xing)(xing)不(bu)(bu)銹(xiu)(xiu)鋼(gang)(gang)(gang)；電阻(zu)率按碳(tan)(tan)鋼(gang)(gang)(gang)、鐵素體型(xing)(xing)(xing)(xing)、馬(ma)(ma)氏(shi)(shi)體型(xing)(xing)(xing)(xing)和奧氏(shi)(shi)體型(xing)(xing)(xing)(xing)不(bu)(bu)銹(xiu)(xiu)鋼(gang)(gang)(gang)排(pai)序依次遞增；線脹(zhang)系數(shu)大小(xiao)的排(pai)序也類似，奧氏(shi)(shi)體型(xing)(xing)(xing)(xing)不(bu)(bu)銹(xiu)(xiu)鋼(gang)(gang)(gang)高而(er)(er)碳(tan)(tan)鋼(gang)(gang)(gang)小(xiao)碳(tan)(tan)鋼(gang)(gang)(gang)、鐵素體型(xing)(xing)(xing)(xing)和馬(ma)(ma)氏(shi)(shi)體型(xing)(xing)(xing)(xing)不(bu)(bu)銹(xiu)(xiu)鋼(gang)(gang)(gang)有磁性，奧氏(shi)(shi)體型(xing)(xing)(xing)(xing)不(bu)(bu)銹(xiu)(xiu)鋼(gang)(gang)(gang)無(wu)磁性，但其冷加工硬化生成馬(ma)(ma)氏(shi)(shi)體相變時將(jiang)會產生磁性，可用熱處(chu)理方法來消除這種馬(ma)(ma)氏(shi)(shi)體組織(zhi)而(er)(er)恢復(fu)其無(wu)磁性。

奧氏體(ti)型不銹鋼與(yu)碳(tan)鋼相比，具有(you)下列特點。

1.電(dian)阻率高，約為(wei)碳鋼的5倍。

2.線(xian)脹(zhang)系(xi)數大，比碳的40%左右，隨著溫(wen)度的升(sheng)高，線(xian)脹(zhang)系(xi)數的數值(zhi)也相應地增加(jia)。

3.熱導率低(di)，約為碳鋼的(de)1/3。

由(you)于奧氏體型不銹鋼(gang)具有這些特(te)殊的物理性能，在焊(han)(han)接(jie)(jie)過(guo)程(cheng)中會引起較大(da)的焊(han)(han)接(jie)(jie)變形(xing)。特(te)別在異種(zhong)金屬（指與碳鋼(gang)、低合金鋼(gang)）焊(han)(han)接(jie)(jie)時，由(you)于這兩種(zhong)材(cai)料的熱導率(lv)和線脹系數有很大(da)差(cha)異，會產生很大(da)的焊(han)(han)接(jie)(jie)殘余應力，也成為焊(han)(han)接(jie)(jie)接(jie)(jie)頭產生裂紋的主要(yao)原因之一。

鍛件的試驗方法有哪些？

其他試驗項目

除上(shang)述試(shi)(shi)驗(yan)項(xiang)目外，如果需方要求進行下列(lie)項(xiang)目試(shi)(shi)驗(yan)，應(ying)在(zai)訂(ding)貨時與(yu)制造(zao)廠(chang)協商，任何這樣的(de)(de)協議(yi)應(ying)包括試(shi)(shi)驗(yan)程序的(de)(de)細節。

取樣位置、取樣數量和(he)試樣制備

鍛件(jian)(jian)上試塊(kuai)(kuai)的留放(fang)位置(zhi)按(an)圖樣(yang)的要求(qiu)決定(ding)(ding)。若圖樣(yang)未注明要求(qiu)時，可由(you)制造(zao)廠(chang)決定(ding)(ding)，但必(bi)須保(bao)證能(neng)代表(biao)鍛件(jian)(jian)的力(li)學性(xing)能(neng)。需方要求(qiu)留放(fang)復試試塊(kuai)(kuai)時，其試塊(kuai)(kuai)的留放(fang)位置(zhi)按(an)協議進行。鍛件(jian)(jian)不便留放(fang)試塊(kuai)(kuai)時，可以破壞(huai)鍛件(jian)(jian)取(qu)樣(yang)，這時制造(zao)廠(chang)應增加試驗用的鍛件(jian)(jian)數量。其他特殊情(qing)況，由(you)制造(zao)廠(chang)與用戶具體議定(ding)(ding)。

試樣(yang)(yang)的切取方向(xiang)(xiang)按圖(tu)樣(yang)(yang)的要(yao)(yao)求決定(ding)，異型鍛件加工定(ding)制，若圖(tu)樣(yang)(yang)未注明(ming)要(yao)(yao)求時，可由制造廠自行選擇（縱(zong)向(xiang)(xiang)、橫向(xiang)(xiang)或切向(xiang)(xiang)）。

取(qu)樣數(shu)量可從每個試塊(kuai)中切取(qu)拉(la)伸(shen)試樣1個，沖擊(ji)試樣2個。需方(fang)根據鍛件的使用條件，也可增加試樣數(shu)量，但應在合同或圖樣中明確(que)規(gui)定(ding)。

切取(qu)后(hou)的(de)試(shi)樣(yang)不得作任(ren)何影響(xiang)力學性能的(de)熱處理。

大家(jia)好(hao)本期小編給大家(jia)帶(dai)來新的(de)內容(rong)，希(xi)望對大家(jia)有所幫助(zhu)：異型鍛(duan)件加工

為了(le)對(dui)鍛(duan)件熱(re)處理(li)的質量進行(xing)控制，車間(jian)應采用一套(tao)配套(tao)的措(cuo)施，其中包括打熱(re)處理(li)爐批號(hao)、抽(chou)查(cha)硬度、定期檢(jian)查(cha)爐溫校核儀表等等。作為參(can)考(kao)，下面列舉了(le)若干基(ji)本(ben)項目：

1)加(jia)熱爐(lu)(lu)的(de)結構要合理(li)。爐(lu)(lu)膛尺寸、爐(lu)(lu)溫(wen)及爐(lu)(lu)膛內溫(wen)度的(de)均勻性能滿足熱處理(li)的(de)需要；

2)淬火槽尺寸要足夠大(da)。保證實現快速、均勻的(de)冷卻。為了控制淬火液的(de)溫度，還(huan)應配有熱交換器；

3)電位計要(yao)定(ding)期校核。加熱(re)爐(lu)應配備控制溫度和記(ji)錄溫度的電位計，由專人檢查記(ji)錄；

4)檢查(cha)(cha)和抽查(cha)(cha)硬(ying)度(du)。硬(ying)度(du)檢查(cha)(cha)是(shi)熱處理的不(bu)可分割的一部分，許多鋼號在回火過程中，往往中途抽取一個鍛件進(jin)行硬(ying)度(du)檢查(cha)(cha)，以(yi)確定是(shi)否需要調整(zheng)溫度(du)；

5)溫度均勻(yun)性(xing)的檢查(cha)。爐溫均勻(yun)性(xing)的檢查(cha)應在正常工(gong)作條(tiao)件(jian)下進行，每(mei)半年一(yi)次；

6)根據(ju)化學成(cheng)分調(diao)整熱(re)處理制度。某(mou)些高溫(wen)合(he)金(jin)或(huo)合(he)金(jin)鋼(gang)，成(cheng)分的(de)微小變化都要求對時效或(huo)回火的(de)佳溫(wen)度作相(xiang)應改變；

7)作好(hao)記(ji)(ji)錄。必須(xu)使熱處(chu)(chu)(chu)理(li)爐的(de)記(ji)(ji)錄與鍛件(jian)的(de)熱處(chu)(chu)(chu)理(li)爐批號相對(dui)應。熱處(chu)(chu)(chu)理(li)爐批號好(hao)是打在鍛件(jian)上熔(rong)煉爐號的(de)旁邊(bian)；
