304不銹鋼彎頭是一種提高不銹鋼強度、耐腐蝕性和奧氏體穩(wěn)定性的有效元素。**近對含氮奧氏體不銹鋼、雙相不銹鋼和馬氏體不銹鋼進行了許多研究。日本大同特殊鋼公司研究開發(fā)部的科研人員用高壓感應(yīng)熔煉法生產(chǎn)含量為、。在各種熱處理制度下對試制鋼的硬度和耐腐蝕性進行了研究，獲得的結(jié)果如下：(1)經(jīng)零下處理硬化后，這些鋼的**硬度隨碳含量的增加而增加，而它們的殘余奧氏體體積分數(shù)隨氮含量的增加而增加。(2)在回火過程中，這些鋼在723-773K時都顯示明顯的二次硬化，并且**硬度隨氮含量的增加而增加。723K回火后馬氏體硬度的變化隨基體中氮的質(zhì)量分數(shù)的增加而增加。淬火狀態(tài)材料的固溶體中的氮含量。(3)回火后這些鋼的耐腐蝕性隨回火溫度的增加而降低。含。不銹鋼牌號分組沉淀硬化型不銹鋼。具有有很好的成形性能和良好的焊接性，可作為超**度的材料在核工業(yè)、航空和航天工業(yè)中應(yīng)用。按成分可分為Cr系（SUS400）、Cr－Ni系（SUS300）、Cr－Mn－Ni（SUS200）及析出硬化系（SUS600）。304—即18/8不銹鋼。GB牌號為0Cr18Ni9。309—較之304有更好的耐溫性。316—繼304之後，第二個得到**廣泛應(yīng)用的鋼種，主要用于食品工業(yè)和外科手術(shù)器材。</p><p>
