Alloy 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. Nws yog ib qho kev lag luam thiab ntau yam corrosion resistant alloy haum rau ntau hom kev siv hom phiaj.
Cov ntaub ntawv Fabrication
Alloy 304/304H tuaj yeem ua tau yooj yim welded thiab ua tiav los ntawm cov qauv kev tsim khoom hauv khw.
Txias txoj kev
Lub alloy yog ductile heev thiab cov ntaub ntawv yooj yim. Kev ua haujlwm txias ua haujlwm yuav ua rau kom lub zog thiab hardness ntawm alloy thiab tej zaum yuav cia nws me ntsis sib nqus.
Kub txoj kev
Ua haujlwm kub ntawm 1652-2102 degree F (750-1150 degree) raug pom zoo rau feem ntau cov txheej txheem ua haujlwm kub. Rau qhov siab tshaj plaws corrosion kuj, cov khoom yuav tsum tau annealed ntawm 1900 degree F (1038 degree) yam tsawg kawg nkaus thiab dej quenched los yog sai txias los ntawm lwm yam txhais tau tias tom qab kub ua hauj lwm.
Tshuab dhos
Alloy 304/304H yog yuav tsum tau ua hauj lwm hardening thaum lub sij hawm deformation thiab yuav raug nti tawg. Cov txiaj ntsig machining zoo tshaj plaws yog ua tiav nrog kev qeeb qeeb, hnyav dua, lubrication zoo, cov cuab yeej ntse thiab cov cuab yeej muaj zog.
