Hom 347 stainless hlau yog dab tsi?
Hom 347 stainless hlau (feem ntau hu ua UNS S34700 / EN 1.4550 / X6CrNiNb18-10) yog niobium-stabilized austenitic stainless hlau. Vim yog qhov sib ntxiv ntawm niobium rau kev ruaj khov, Hom 347 stainless hlau tiv thaiv chromium carbide nag lossis daus thaum lub sij hawm vuam lossis siab - qhov kub thiab txias, ua rau nws ruaj khov dua li tsis yog - cov qib ruaj khov xws li 304 hauv vuam lossis cov ntawv siv kub. Hais txog cov khoom siv thermal, Hom 347 stainless hlau tuaj yeem tiv taus qhov kub thiab txias (piv txwv li, hauv cov tub rauv thiab superheaters) thaum tuav lub zog thiab tiv thaiv kev kub ntxhov.
Hom 347 Stainless Hlau Yeeb Nkab Nqe ib kg
Tus nqi ntawm Hom 347 stainless hlau yeeb nkab hloov pauv ntau zaus, cuam tshuam los ntawm cov khoom siv raw khoom, kev xav tau thoob ntiaj teb stainless-steel, alloy surcharges, thiab kev lag luam kev lag luam. Raws li cov ntaub ntawv tsis ntev los no 2025, cov nqi lag luam raug nqi rau 347 stainless hlau kav yog nyob ib ncig ntawm USD 5.50-6.50 ib kg (rau cov qauv seamless lossis welded 347 kav), raws li kev cai thoob ntiaj teb cov nqi stainless hlau.
Vim li cas Hom 347 Yeeb Nkab Nqe Sib txawv - Kev Ua Lag Luam & Kev Siv Khoom Siv
Ob peb yam tsav variations nyob rau hauv tus nqi ib kg ntawm 347 stainless hlau yeeb nkab:
Cov nqi raw khoom: Nickel thiab chromium tus nqi cuam tshuam rau cov nqi hlau.
Alloy surcharge / ntau lawm nqi: Niobium stabilization thiab yuav tsum tau ua (seamless, welded, xov) nce nqi piv rau yooj yim stainless hlau.
Cov yeeb nkab loj thiab phab ntsa tuab: Loj - txoj kab uas hla lossis tuab - cov kav dej phab ntsa siv cov khoom siv ntau dua ib 'meter', nce nqi ib kg.
Kev ua haujlwm thiab ua tiav: Polishing, pickling, ntawv pov thawj, kev cai ntev nce nqi.
Volume, kev txiav txim nplai, thiab cov nqe lus xa khoom: Kev txiav txim me me lossis kev xa sai feem ntau ua rau tus nqi siab dua ib-kg piv rau cov xaj ntau.

Vim li cas 347 stainless hlau kav yog kim dua 304 lossis 316 stainless hlau kav?
347 stainless hlau kav yog kim tshaj 304 los yog 316 stainless hlau kav feem ntau vim yog ntxiv ntawm niobium rau stabilization thiab nws superior siab - kub ua haujlwm. Yog li ntawd, nws yog qhov zoo tshaj plaws rau kev siv rau hauv cov kav dej kub, superheaters, thiab welded siab hlab ntsha. Qhov tshwj xeeb alloy muaj pes tsawg leeg thiab cov txheej txheem tsim khoom nruj ua kom cov khoom siv raw thiab cov nqi ua haujlwm, ua rau tus nqi ib kilogram uas yog 5% mus rau 15% siab dua tus qauv 304 lossis 316 stainless hlau kav.
Cov yeeb nkab txoj kab uas hla thiab phab ntsa thickness cuam tshuam li cas rau tus nqi ib kilogram?
Tus nqi ib kilogram ntawm 347 stainless hlau kav yog cuam tshuam los ntawm cov yeeb nkab txoj kab uas hla thiab phab ntsa thickness vim hais tias loj txoj kab uas hla los yog tuab dua - cov kav dej uas muaj phab ntsa yuav tsum tau ntau cov khoom ib 'meter'. Piv txwv li, cov yeeb nkab uas muaj 50 hli txoj kab uas hla thiab 3 hli phab ntsa thickness hnyav dua li ib 'meter' dua li cov yeeb nkab nrog 200 hli txoj kab uas hla thiab 10 hli phab ntsa thickness, yog li txawm tias nrog tib tus nqi alloy, tag nrho cov khoom siv tau nce. Tsis tas li ntawd, cov kav dej tuab lossis loj dua feem ntau yuav tsum tau ua ntau dua dov, vuam, thiab ua tiav cov txheej txheem, uas ua rau tus nqi tiag tiag rau ib kilogram.
Puas yog vuam los yog ua tiav kom nce tus nqi ntawm 347 stainless hlau kav?
Yog lawm. Vuam, pickling, polishing, lossis kho cua sov ua kom tus nqi ntawm 347 stainless hlau kav. Vuam yuav tsum tau tswj cov txheej txheem nruj kom tswj tau cov nyhuv ruaj khov ntawm niobium thiab tiv thaiv kev puas tsuaj, thaum ua tiav cov txheej txheem (xws li pickling thiab passivation los yog iav polishing) ntxiv zog, tshuaj, thiab tshuaj xyuas cov kauj ruam. Welded thiab polished kav yuav tsum raug nqi 10% mus rau 20% ntau dua li cov qauv kub - dov los yog dov seamless kav.
