ALLOY 800 • UNS N08800 • WNR 1.4876
Alloy 800, 800H, thiab 800HT yog npib tsib xee-hlau-chromium alloys nrog lub zog zoo thiab zoo heev tiv thaiv oxidation thiab carburization nyob rau hauv high-temperature raug. Cov nickel steel alloys zoo ib yam tshwj tsis yog rau qib siab dua ntawm cov pa roj carbon ntau hauv alloy 800H / HT thiab ntxiv txog li 1.20 feem pua ntawm txhuas thiab titanium hauv alloy 800HT. 800 yog thawj zaug ntawm cov alloys thiab nws tau hloov me ntsis rau hauv 800H. Qhov kev hloov kho no yog los tswj cov pa roj carbon (.05-.10%) thiab cov nplej loj los ua kom zoo dua cov khoom muaj zog rupture. Hauv kev kho cua sov daim ntawv thov 800HT muaj kev hloov kho ntxiv rau kev sib xyaw ua ke ntawm titanium thiab txhuas qib (.85-1.20%) kom ntseeg tau tias qhov zoo ntawm qhov kub thiab txias. Alloy 800H / HT tau npaj rau kev siv cov txheej txheem kub. Cov ntsiab lus npib tsib xee ua rau cov alloys tiv taus ob qho tib si carborisation thiab embrittlement los ntawm nag lossis daus ntawm sigma theem.
