Inconel 686(UNS N06686）合金的分析與研究
Inconel?686(UNS N06686/W.Nr. 2.4606)
INCONEL? alloy 686
An alloy designed for outstanding corrosion resistance in a wide range of severe environments. The alloy is used in the most severe environments encountered in chemical processing, pollution control, pulp and paper production, and treatment of industrial and municipal wastes. Chemical processing uses include heat exchangers, reaction vessels, evaporators, and transfer piping. Air pollution control applications are stack liners, ducts, dampers, scrubbers, stack-gas re-heaters, fans, and housings.INCONEL alloy 686 is stocked & distributed by Corrosion Materials and BIBUS Metals AG.
Inconel 686/N06686是NI-Cr-Mo固溶強(qiáng)化耐蝕鎳基合金，在惡劣的腐蝕環(huán)境中具有杰出的耐蝕性,主要應(yīng)用于化學(xué)處理,污染控制,造紙,工業(yè)及城市垃圾處理等的熱交換器,反應(yīng)容器,輸送管等.
據(jù)美國享廷頓特種材料公司報(bào)道,具有優(yōu)異的抗腐蝕特性的Inconel 686合金已取代了美國海軍艦船使用的K一500合金用作連接件。 686合金是一種固溶強(qiáng)化型合金,通過冷加工獲得高的強(qiáng)度。特別是經(jīng)冷加工后的686合金顯示出杰出的耐氫脆和抗蝕性能,諸如優(yōu)異的強(qiáng)度、延性和韌性。 采用直徑為38Inm(15英寸)冷加工的686合金棒材制作1.3×33cm(0.5×13英寸)的螺栓具有993MPa的標(biāo)準(zhǔn)的R1Tr極限抗張強(qiáng)度,這些經(jīng)加工的螺栓在加工后的連接件和楔形張力測(cè)試中部顯示出良好的性能。
