Thaum muas 304 stainless hlau kav, koj puas tau ntsib qhov teeb meem no: muab cov khoom siv qib zoo tib yam (304), vim li cas cov lus hais los ntawm cov neeg muag khoom sib txawv sib txawv heev? Yuav ua li cas raws nraim ib tug yuav txhais ib daim ntawv teev nqi? Thiab koj tuaj yeem txiav txim siab tau li cas tias koj tab tom raug dag los ntawm "qis-tus nqi cuab"?
Raws li kev lag luam tam sim no, tsab xov xwm no yuav rhuav tshem tus nqi ntawm 304 stainless hlau kav thiab muab cov nqi siv los pab cov neeg yuav khoom thiab cov kws tsim khoom hauv kev txiav txim siab paub ntau ntxiv.
GNEE, raws li ib tug neeg muag khoom nrog ntau tshaj 18 xyoo ntawm kev paub nyob rau hauv stainless hlau manufacturing, siab nkag siab tias tus nqi ntawm304 stainless hlau kavtsis kho. Nws feem ntau yog tsav los ntawm plaub yam tseem ceeb hauv qab no:
1. LME Nickel Nqe
304 stainless hlau muaj kwv yees li 8% npib tsib xee. Txawm tias muaj kev hloov pauv me ntsis hauv London Hlau Txauv (LME) tus nqi npib tsib xee tuaj yeem ua rau muaj kev sib txuas lus, cuam tshuam ncaj qha rau koj cov lus hais.
2. Qhov sib txawv ntawm cov txheej txheem ntau lawm
Welded Pipes (ERW):Tus nqi qis dua, tsim nyog rau kev siv cov txheej txheem.
Seamless Yeeb Nkab:Superior siab tsis kam, zoo tagnrho rau siab -xav tau kev lag luam.
Tswv yim:Ntau yam tsawg - nqe muab feem ntau hloov welded kav rau seamless kav, qhov no yuav tsum tau saib xyuas tshwj xeeb.
3. Cov Qauv (ASTM / EN / JIS)
Cov qauv sib txawv muaj cov kev cai sib txawv rau cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab. Piv txwv li:
ASTM A312 Txuj:Cov qauv siab dua
ASTM A778 Cov Lus Qhia:Tus qauv qis dua
Tus qauv siab dua, tus nqi siab dua, tab sis kuj tseem muaj kev ntseeg siab dua.
4. Nto tiav & Kev soj ntsuam yuav tsum tau ua
Polishing, pickling, thiab tsis yog -kev kuaj kev puas tsuaj (xws li UT thiab RT) tag nrho cov nqi nce, tab sis lawv kuj cuam tshuam ncaj qha rau kev pab cuam lub neej thiab kev nyab xeeb.
