20G高壓鍋爐管是，但對(duì)制造鋼管所用的鋼種有嚴(yán)格的要求。20G高壓鍋爐管使用時(shí)經(jīng)常處于高溫和高壓條件，管子在高溫?zé)煔夂退魵獾淖饔孟?，?huì)發(fā)生氧化和腐蝕。要求鋼管具有高的持久強(qiáng)度，高的抗氧化腐蝕性能，并有良好的組織穩(wěn)定性。高壓鍋爐管主要用來制造高壓和超高壓鍋爐的過熱器管、再熱器管、導(dǎo)氣管、主蒸汽管等。 </p> <p> 20G高壓鍋爐管采用的鍋爐受壓元件用鋼,一般在39公斤以下的鍋爐應(yīng)用，為了在較高壓力下使用，往往都把受熱面管設(shè)計(jì)的很厚。為了減少熱阻和節(jié)省鋼材，保證較高或高壓鍋爐用鋼的性，同時(shí)也為了降低用鋼量，普遍采用的是16MnG。同時(shí)也有添加稀土、鎂等金屬和非金屬材料的特殊鋼材。這樣會(huì)提高鍋爐用鋼的性能，減少鋼材的耗量，同時(shí)也降低了熱阻。

鍋爐管回火方法：將淬火成馬氏體的20G高壓鍋爐管加熱到臨界點(diǎn)以下某個(gè)溫度，保溫適當(dāng)時(shí)間，再冷到室溫的一種熱處理工藝。回火的目的在于淬火應(yīng)力，使高壓鍋爐管的組織轉(zhuǎn)變?yōu)橄鄬?duì)穩(wěn)定狀態(tài)。在不降低或適當(dāng)降低鋼管的硬度和強(qiáng)度的條件下改善鋼的塑性和韌性，以獲得所希望的性能。中碳和高碳鋼淬火后通常硬度很高，但很脆，一般需經(jīng)回火處理才能使用。高壓鋼管中的淬火馬氏體，是碳在-Fe中的過飽和固溶體，具有體心正方結(jié)構(gòu)，其正方度/隨含碳量的增加而增大。馬氏體組織在熱力學(xué)上是不穩(wěn)定的，有向穩(wěn)定組織過渡的趨勢(shì)。許多鋼淬火后還有一定量的殘留奧氏體，也是不穩(wěn)定的，回火過程中將發(fā)生轉(zhuǎn)變。因此，回火過程本質(zhì)上是在一定溫度范圍內(nèi)加熱粹火20G高壓鍋爐管，使鋼中的熱力學(xué)不穩(wěn)定組織結(jié)構(gòu)向穩(wěn)定狀態(tài)過渡的復(fù)雜轉(zhuǎn)變過程。轉(zhuǎn)變的內(nèi)容和形式則視淬火高壓鍋爐管的化學(xué)成分和組織，以及加熱溫度而有所不同。
