Cov txheej txheem ua thiab tsim cov kav dej ua los ntawm cov hlau tsis xeb uas muaj zog heev txawv ntawm cov kav dej tsis sib xws ib txwm muaj. Cov kav dej tsis sib xws ib txwm muaj feem ntau yog tsim los ntawm ob-yob hla-yob kub perforation, thiab cov txheej txheem tsim cov kav dej feem ntau siv cov txheej txheem kos duab. Cov kav dej ua los ntawm cov hlau tsis xeb feem ntau siv rau hauv cov cuab yeej ua haujlwm raug lossis cov khoom siv kho mob. Tsis yog tsuas yog tus nqi siab xwb, tab sis lawv kuj feem ntau siv rau hauv cov khoom siv tseem ceeb thiab cov cuab yeej siv. Yog li ntawd, qhov yuav tsum tau ua rau cov khoom siv, qhov tseeb thiab qhov tiav ntawm cov kav dej ua los ntawm cov hlau tsis xeb uas muaj zog heev.

Cov raj ua los ntawm cov khoom siv ua tau zoo thiab nyuaj rau tsim feem ntau yog tsim los ntawm kev kub extrusion, thiab kev tsim cov raj feem ntau yog ua los ntawm kev dov txias. Cov txheej txheem no yog tus cwj pwm los ntawm kev ua haujlwm siab, kev hloov pauv yas loj, thiab cov yam ntxwv zoo ntawm cov yeeb nkab, yog li lawv tau siv.

Feem ntau cov kav dej stainless hlau precision pej xeem yog 301 stainless hlau, 304 stainless hlau, 316 stainless hlau, 316L stainless hlau, 310S stainless hlau. Feem ntau, ntau dua NI8 cov ntaub ntawv raug tsim, uas yog, cov ntaub ntawv saum toj no 304, thiab cov kav dej stainless hlau precision nrog cov ntaub ntawv qis tsis raug tsim.

Nws yog ib txwm hu ua 201 thiab 202 stainless hlau, vim nws yog hlau nplaum thiab muaj kev nyiam rau cov hlau nplaum. 301 kuj tsis yog hlau nplaum, tab sis nws yog hlau nplaum tom qab ua haujlwm txias thiab muaj kev nyiam rau cov hlau nplaum. 304, 316 tsis yog hlau nplaum, tsis muaj kev nyiam rau cov hlau nplaum, thiab tsis lo rau cov hlau nplaum. Qhov laj thawj tseem ceeb rau seb nws yog hlau nplaum lossis tsis yog vim tias cov khoom siv stainless hlau muaj chromium, nickel thiab lwm yam khoom hauv ntau qhov sib txawv thiab cov qauv metallographic. Ua ke nrog cov yam ntxwv saum toj no, nws kuj yog ib txoj hauv kev siv cov hlau nplaum los txiav txim siab qhov zoo ntawm cov hlau nplaum, tab sis txoj kev no tsis yog kev tshawb fawb, vim tias hauv cov txheej txheem tsim khoom ntawm cov hlau nplaum, muaj kev kos duab txias, kev kos duab kub, thiab kev kho mob zoo dua tom qab, yog li qhov magnetism tsawg dua lossis tsis muaj. Yog tias nws tsis zoo, qhov magnetism yuav loj dua, uas tsis tuaj yeem cuam tshuam qhov huv ntawm cov hlau nplaum. Cov neeg siv kuj tuaj yeem txiav txim siab los ntawm kev ntim khoom thiab qhov tsos ntawm cov kav hlau stainless hlau precision: roughness, uniform thickness, thiab seb puas muaj cov xim ntawm qhov chaw.

Cov txheej txheem dov thiab kos duab tom qab ntawm kev ua cov yeeb nkab kuj tseem ceeb heev. Piv txwv li, kev tshem tawm cov roj nplua nyeem thiab cov oxides ntawm qhov chaw hauv extrusion tsis zoo tagnrho, uas yuav cuam tshuam rau qhov tseeb thiab qhov zoo ntawm qhov chaw ntawm cov yeeb nkab stainless hlau precision.
