ASTM B777 Tungsten Base High Density Hlau
ASTM thiab AMS specifications txawv me ntsis ntawm qhov sib txawv ntawm cov ntawv sib nqus thiab cov ntawv tsis sib nqus. AMS 7725 txhais cov hlau tsis sib nqus raws li Hom 1 thiab cov hlau nplaum sib nqus raws li Hom 2. Tsis tas li ntawd, AMS specification hais tias yog hom 1, hom 1 yuav tsum muab. Tsis tau teev tseg, yog tias hom tsis tau teev tseg, qhov sib txawv ntxiv ntawm Hom 2 ASTM thiab AMS cov lus qhia tshwj xeeb yuav tsum tau muab: AMS 7725 muaj qhov tshwj xeeb configuration hu ua "sintered thiab annealed."
Lwm qhov sib txawv ntawm ASTM thiab AMS specifications: AMS 7725 muaj ib qho tshwj xeeb configuration hu ua "sintered thiab annealed." Qee zaum cov duab kos yuav qhia meej "thiab annealed" thaum tus neeg siv khoom xav tau kev txhim kho elongation khoom lossis rau lwm yam laj thawj. Qhov no yuav tsum muaj cov kauj ruam ntxiv ntawm lub tshuab nqus tsev annealing. Yog tias tsuas yog "sinter conditions" tau teev tseg, lub tshuab nqus tsev tsis tas yuav tsum tau ua.

FAQ
Q: Dab tsi yog qhov zoo ntawm koj lub tuam txhab?
A: Peb muaj ntau tus kws tshaj lij, cov kws tshaj lij, cov nqi sib tw ntau dua thiab cov kev pabcuam zoo tshaj plaws tom qab muag tshaj li lwm cov tuam txhab stainless hlau.
Q: Koj puas tuaj yeem xa cov qauv?
A: Tau kawg, peb tuaj yeem xa cov qauv mus rau thoob plaws ntiaj teb, peb cov qauv dawb, tab sis cov neeg siv khoom yuav tsum tau them tus nqi nthuav tawm.
Q: Cov ntaub ntawv khoom dab tsi kuv yuav tsum tau muab?
A: Koj yuav tsum muab qib, dav, tuab, txheej thiab tonnage koj xav tau.
Q: Hais txog tus nqi khoom ntawmASTM B777 Tungsten Base High Density Hlau?
A: Vim muaj kev hloov pauv hauv cov nqi raw khoom, cov nqi sib txawv nyob rau lub sijhawm sib txawv.
