專門研究解決膛的磨損問題。布雷爾利和其助手搜集了國(guó)內(nèi)外生產(chǎn)的各種型號(hào)的鋼材，各種不同性質(zhì)的合金鋼，在各種不同性質(zhì)的機(jī)械上進(jìn)行性能實(shí)驗(yàn)，然后選擇出較為適用的鋼材制成支。，他們實(shí)驗(yàn)了一種含大量鉻的國(guó)產(chǎn)合金鋼，經(jīng)耐磨實(shí)驗(yàn)后，查明這種合金并不耐磨，說明這不能制造支，于是，他們記錄下實(shí)驗(yàn)結(jié)果，往墻角一扔了事。幾個(gè)月后的，一位助手拿著一塊锃光瓦亮的鋼材興沖沖跑來對(duì)布雷爾利說：“先生，這是我在清理倉(cāng)庫(kù)時(shí)發(fā)現(xiàn)的毛拉先生送來的合金鋼，您是否實(shí)驗(yàn)一下，看它到底有什么特殊作用！”“好！”布雷爾利看著光亮耀眼的鋼材，高興地說。實(shí)驗(yàn)結(jié)果證明：它是一塊不怕酸、堿、鹽的不銹鋼。這種不銹鋼是德國(guó)的毛拉在1912年發(fā)明的，然而，毛拉卻并不知道這種不銹鋼有什么用途。布雷爾利心里盤算道：“這種不耐磨卻耐腐蝕的鋼材，不能制枝，是否可以做餐具呢？”他說干就干，動(dòng)手制作了不銹鋼的水果刀、叉、勺、果盤及折疊刀等。主要類型編輯不銹鋼常按組織狀態(tài)分為：馬氏體鋼、鐵素體鋼、奧氏體鋼、奧氏體-鐵素體（雙相）不銹鋼及沉淀硬化不銹鋼等。另外，可按成分分為：鉻不銹鋼、鉻鎳不銹鋼和鉻錳氮不銹鋼等。</p><p>

不銹鋼冷加工硬化傾向的影響，鎳降低奧氏體不銹鋼冷加工硬化速率，與降低鋼的室溫及低溫強(qiáng)度。提高塑性的作用，決定了鎳含量的提高有利于奧氏體不銹的冷加工成形性能，提高鎳含量還可減少以至消除18-8和17-14-2型鉻鎳奧氏體不銹鋼中的δ鐵素體。從而提高其熱加工性能，但是，δ鐵素體的減少對(duì)這些鋼種的可焊接性不利會(huì)增大焊接熱裂紋絲傾向，此外，鎳還可提高鉻錳氮（鉻錳鎳氮）奧氏體不銹鋼的熱加工性能，從而提高鋼的成材率，在奧氏體不銹鋼中，鎳的加入以及隨著鎳含量的提高，導(dǎo)致鋼的熱力學(xué)穩(wěn)定性增加，因此奧氏體不銹鋼具有更好的不銹性和耐氧化性介質(zhì)的性能，且隨著鎳含量增加，耐還原性介質(zhì)的性能進(jìn)一步得到改善.值得指出，鎳還是提高奧氏體不銹耐許多介質(zhì)穿晶型應(yīng)力腐蝕的重要元素，在各種酸介質(zhì)中鎳對(duì)奧氏體不銹鋼耐蝕性能的影響，需要指出，在高溫高壓水中的一些條件下，鎳含量的提高導(dǎo)致鋼和合金的晶間型應(yīng)力腐蝕敏感性增加，但是這種不利作用會(huì)由于鋼及合金中鉻含量的提高而獲得減輕或受到抑制.隨磁卡奧氏體不銹鋼中鎳含量的提高，其產(chǎn)生晶間腐蝕的臨界碳含量降低，即鋼的晶間腐蝕敏感性增加，至于對(duì)奧氏體不銹鋼耐點(diǎn)腐蝕及縫隙腐蝕的性能，鎳的作用并不。GB/T12770-2002（機(jī)械結(jié)構(gòu)用不銹鋼焊接鋼管）。主要用于機(jī)械、汽車、自行車、家具、賓館等結(jié)構(gòu)件。廣西430不銹鋼無縫焊管供應(yīng)</p><p
