Khoom Description
304/304H (UNS S30400 / S30409) yog ib qho kev hloov kho ntawm feem ntau siv "18-8" chromium-nickel austenitic stainless hlau. Cov ntsiab lus carbon yog tswj nyob rau hauv thaj tsam ntawm 0.04-0.10% kom muaj zog ntxiv ntawm qhov kub siab tshaj 800℃F (427 degree). Nws yog ib qho kev lag luam thiab ntau yam corrosion resistant alloy haum rau ntau hom kev siv hom phiaj.
Nws yog ib qho kev xyaum rau 304H kom tau txais daim ntawv pov thawj dua li 304 thiab 304H. Lub siab carbon chemistry ntawm 304H enables 304 kom tau raws li cov neeg kho tshuab zog thiab grain loj yuav tsum tau ntawm 304H.
304/304H muaj dav dav corrosion kuj zoo ib yam li 304/304L. Nws tiv taus atmospheric corrosion, nrog rau, me ntsis oxidizing thiab txo qhov chaw. Txawm li cas los xij, vim nws cov ntsiab lus carbon siab, 304/304H raug rau carbide nag lossis daus hauv tshav kub cuam tshuam ntawm welds.
304/304H tsis yog-sib nqus nyob rau hauv cov mob annealed tab sis tuaj yeem dhau los ua cov hlau nplaum me ntsis vim kev ua haujlwm txias lossis vuam. Nws tuaj yeem ua tau yooj yim welded thiab ua tiav los ntawm cov txheej txheem khw fabrication.
