Txheej txheem cej luam ntawm alloy steel yeeb nkab

Ib cov yeeb nkab alloy yog siv rau hauv cov ntawv thov uas xav tau cov khoom siv corrosion tsis kam thiab ua tau nqi. Txhawm rau kom muab nws, alloy kav yog nyiam nyob rau hauv cov chaw uas cov roj hlau uas muaj cov roj hlau steel yuav swb. Muaj ob chav ntawm alloy steels - high alloys thiab tsawg alloy class. Cov kav dej uas suav tau cov hlau qis qis muaj cov ntsiab lus alloy uas nyob hauv qab 5%. Whereas cov ntsiab lus alloy ntawm cov hlau loj feem ntau yuav muaj nyob ntawm 5% txog li 50%. Zoo ib yam li cov alloys lub siab muaj peev xwm ntawm cov yeeb nkab alloy tsis sib xws yog li 20% siab dua li ntawm cov yeeb nkab welded. Yog li nyob rau hauv cov ntawv thov uas muaj kev ua haujlwm siab dua ua qhov ua ntej, kev siv ntawm cov yeeb nkab uas tsis paub tab. Txawm muaj zog dua li cov yeeb nkab welded, tus nqi yog ntau dua. Tsis tas li ntawd, kev pheej hmoo ntawm intergranular corroos ntawm lub tshav kub cuam tshuam weld cheeb tsam yog ntau dua hauv cov khoom welded. Qhov pom sib txawv ntawm ib qho alloy steel welded yeeb nkab thiab cov khoom seamless yog cov nqaij ntas ib txwm muaj ntawm cov yeeb nkab. Txawm li cas los xij, hnub no, nrog kev nce qib hauv thev naus laus zis, cov leeg tuaj yeem txo ntawm kev kho mob saum npoo av, xws li nws tseem tsis tuaj yeem pom tib neeg lub qhov muag.
