Hauv kev lag luam siab -kub alloy, cov ntsiab lus "siab-kub alloy" thiab "corrosion-resistant alloy" feem ntau siv sib hloov los ntawm cov neeg yuav khoom. Txawm li cas los xij, rau cov engineers, lawv sawv cev rau ob qhov kev thov ib puag ncig.
Pain Point:Peb nquag pom ntau - lab daus las cov cuab yeej ua tsis tiav hauv lub lis piam tsuas yog vim tus neeg yuav khoom xaivGH4169 (sib npaug rau alloy 718)rau siab -acid reactors tsuas yog vim nws yog "robust thiab kim." Conversely, sivHastelloy C276rau ib tug rotating ncej ntawm700 degreeyuav ua rau nws sag tam sim ntawd vim nws tsis muaj mechanical "stiffness" ntawm qhov kub thiab txias.
Xaiv ntawmGH4169 thiab C276tsis yog hais txog qhov twg yog "zoo dua," tab sis hais txog kev lag luam - tawm ntawm cov khoom thauj khoom thiab tshuaj lom neeg corrosion. Ntawm Gnee Alloy, peb ua kom lub zog ntawm koj cov khoom lag luam los ntawm kev sib piv cov alloy tsim nyog rau koj qhov kev ua haujlwm tiag tiag.
