高氮奧氏體不銹鋼是含氮量在，用氮元素代替昂貴的鎳元素作為奧氏體化元素的新型鋼種[1]，由于其特有的成本優(yōu)勢，近些年許多學(xué)者對高氮鋼研制及應(yīng)用進(jìn)行了進(jìn)一步深入研究，發(fā)現(xiàn)其具有良好的力學(xué)性能和耐腐蝕性能，在生物醫(yī)藥、海洋平臺，南京SKD-11焊條工廠、大型設(shè)備等各個(gè)領(lǐng)域得到推廣和應(yīng)用[2]。尤其值得一提的是，由于這種材料在高應(yīng)變沖擊下強(qiáng)度及韌性較常規(guī)材料有明顯提高，這為重載及承受沖擊載荷的設(shè)備開發(fā)提供了新型材料。高氮鋼的比強(qiáng)度、比剛度隨著含氮量的提高也有明顯提升，高的比強(qiáng)度和比剛度能明顯減輕結(jié)構(gòu)重量，因此市場對高含氮量的材料需求更為迫切，目前含氮量在。高氮鋼的實(shí)際應(yīng)用在很大程度上受限于它的焊接性能，南京SKD-11焊條工廠，在焊接過程中，氮元素易在熔池中聚集成逸出，導(dǎo)致焊接接頭部位含氮量***降低，力學(xué)性能急劇下降[3]。如何降低焊接過程中的氮損失，或者在焊接過程中通過人為干預(yù)，向熔池中增氮，成為解決高氮鋼焊接的技術(shù)關(guān)鍵，南京SKD-11焊條工廠，這對高氮鋼的焊接材料提出了很高的要求。目前的高氮焊絲開發(fā)，一般都是基于成分匹配及焊接接頭組.織匹配原則開發(fā)的[4]，因而需要深入考察焊絲的焊接工藝性。若焊接工藝性不好，一方面氮的聚集和逸出容易導(dǎo)致氮?dú)饪缀瓦^大的焊接飛濺。焊條氣焊或電焊時(shí)熔化填充在焊接工件的接合處的金屬條。焊條的材料通常跟工件的材料相同。南京SKD-11焊條工廠</p><div

中間消除應(yīng)力熱處理對消除焊接殘余應(yīng)力具有積極作用，為保證堆焊層的耐蝕及抗裂性能，條件允許下應(yīng)盡量進(jìn)行中間消除應(yīng)力熱處理。（4）總結(jié)與應(yīng)用①各廠家309LMo及316L藥芯焊絲焊接工藝性能良好，無明顯差異，GT廠焊絲組合過渡層焊絲與面層焊絲配合優(yōu)良，可得到無論是化學(xué)成分還是鐵素體含量（圖示法及磁性儀法兩種檢測方法）均較穩(wěn)定的堆焊層組.織。②各廠家焊絲組合堆焊試樣按GB/T4334方法E法進(jìn)行晶間腐蝕試驗(yàn)通過，晶間腐蝕性能滿足標(biāo)準(zhǔn)技術(shù)要求。GT及DS焊絲堆焊層塑性良好，彎曲試驗(yàn)未出現(xiàn)彎裂現(xiàn)象，JQ焊絲堆焊層塑性相對略差，出現(xiàn)了彎裂現(xiàn)象。各廠家藥芯焊絲組合堆焊層硬度性能均滿足氣化爐相關(guān)技術(shù)要求。③各廠家藥芯焊絲堆焊組合中：GT公司藥芯焊絲綜合性能更為良好，可選擇其用于氣化爐不銹鋼藥芯焊絲氣保焊堆焊，已成功應(yīng)用于我公司多個(gè)氣化爐項(xiàng)目；DS公司藥芯焊絲堆焊層化學(xué)成分及鐵素體含量（按WRC計(jì)算FN偏高）均勻穩(wěn)定性有待提高，并需進(jìn)一步的驗(yàn)證；JQ公司藥芯焊絲鐵素體含量偏下限，且堆焊焊縫塑性較差，需提高和進(jìn)一步的驗(yàn)證。3.結(jié)語（1）堆焊316L藥芯焊絲時(shí)采用309LMo藥芯焊絲進(jìn)行過渡層焊接可起到很好緩沖母材稀釋影響的過渡作用。南京SKD-11焊條工廠在焊接過程中，錳也是一種較好的脫氧劑，能減少焊縫中氧的含量。</p><div
