</p> <p> </p> <p> 不銹鋼管是一種中空的長條鋼材，大量用作輸送流體的管道，如石油、天燃氣、水、煤氣、蒸氣等，另外，在搞彎、抗扭強度相同時，重量較輕，所以也廣泛用于制造機械零件和工程結構。也常用作生產各種常規(guī)武器、槍管、炮彈等。 </p> <p> <br /> 分類 </p> <p>  </p> <p> 鋼管分無縫鋼管和焊接鋼管（有縫管）兩大類。按斷面形狀又可分為圓管和異形管，廣泛應用的是圓形鋼管，但也有一些方形、矩形、半圓形、六角形、等邊三角形、八角形等異 </p> <p> 形鋼管。<br /> 對于承受流體壓力的鋼管都要進行液壓試驗來檢驗其耐壓能力和質量，在規(guī)定的壓力下不發(fā)生泄漏、浸濕或膨脹為合格，有些鋼管還要根據標準或需方要求進行卷邊試驗、擴口試驗、壓扁試驗等。 </p> <p> 無縫不銹鋼管也稱不銹鋼無縫管,是用鋼錠或實心管坯經穿孔制成毛管，然后經熱軋、冷軋或冷撥制成。無縫鋼管的規(guī)格用外徑*壁厚毫米數(shù)表示。 </p></div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/142/1249/202402220322368094.jpg"

精密管低溫回火脆性合金鋼淬火得到馬氏體組織后，在250～400℃溫度范圍回火使鋼脆化，其韌性一脆性轉化溫度明顯升高。已脆化的精密管不能再用低溫回火加熱的方法，故又稱為%26ldquo;不可逆回火脆性%26rdquo;。它主要發(fā)生在合金結構鋼和低合金超高強度精密管等鋼種。已脆化精密管的斷口是沿晶斷口或是沿晶和準解理混合斷口。產生低溫回火脆性的原因，普遍認為：(1)與滲碳體在低溫回火時以薄片狀在原奧氏體晶界析出，造成晶界脆化密切相關。(2)雜質元素磷等在原奧氏體晶界偏聚也是造成低溫回火脆性原因之一。含磷低于0.005%的高純精密管并不產生低溫回火脆性。磷在火加熱時發(fā)生奧氏體晶界偏聚，淬火后保留下來。磷在原奧氏體晶界偏聚和滲碳體回火時在原奧氏體晶界析出，這兩個因素造成沿晶脆斷，促成了低溫回火脆性的發(fā)生。 </p> <p> 精密管中合金元素對低溫回火脆性產生較大的影響。鉻和錳促進雜質元素磷等在奧氏體晶界偏聚，從而促進低溫回火脆性，鎢和釩基本上沒有影響，鉬降低低溫回火精密管的韌性一脆性轉化溫度，但尚不足以抑制低溫回火脆性。硅能推遲回火時滲碳體析出，提高其生成溫度，故可提高精密管低溫回火脆性發(fā)生的溫度。 </p></div><p><img
