304l polished stainless hlau taw qhia
304L polished stainless hlau panels yog qib steel tau los ntawm kev txo cov ntsiab lus carbon ntawm 304 rau qis dua 0.03%. Nws cov yam ntxwv dav dav yuav luag zoo ib yam li 304, tab sis 304L stainless hlau tuaj yeem cuam tshuam qhov rhiab heev los ntawm nag lossis daus ntawm chromium carbide ntawm 500 thiab 900oC. , los txhim kho qhov rhiab heev ntawm intergranular corrosion tshwm sim los ntawm vuam, thiab lwm yam, yog li nws yog haum rau loj welded structural cov ntaub ntawv thiab cov yeeb nkab fittings uas yuav tsum tau siv ncaj qha tom qab vuam.

Kev siv 304L stainless hlau
304L buffing ss phaj yog ib qho ultra-low carbon version ntawm 304 steel alloy. Cov ntsiab lus qis dua hauv 304L txo qis carbide nag lossis daus los ntawm vuam. Yog li ntawd, 304L tuaj yeem "welded" nyob rau hauv ib puag ncig corrosive hnyav thiab tsis tas yuav tsum tau annealing. Qib no muaj cov khoom siv kho tshuab qis dua li tus qauv 304 qib, tab sis tau siv dav vim nws muaj ntau yam. Zoo li Hom 304 stainless hlau, nws yog feem ntau siv hauv npias brewing thiab winemaking, tab sis kuj rau lub hom phiaj sab nraum kev lag luam zaub mov, xws li cov ntim tshuaj, mining thiab kev tsim kho. Qhov zoo tshaj plaws rau cov khoom siv hlau xws li txiv ntseej thiab bolts uas yuav raug rau cov dej ntsev
Cov yam ntxwv ntawm 304L stainless hlau
Qhov txawv ntawm 304L stainless hlau thiab 304 stainless hlau: 304L muaj nickel ntau dua li 304 stainless hlau, thiab muaj me ntsis ntau nickel, thiab tseem ceeb tshaj, 304L muaj cov pa roj carbon tsawg dua 304. 304L stainless hlau phaj zoo dua 304 hauv kev tiv thaiv. pitting corrosion ntawm cov ntsiab lus vuam lossis lwm qhov chaw ua haujlwm. 304L yog ntau corrosion-resistant, 304L muaj cov pa roj carbon tsawg, 304 yog dav siv, muaj corrosion kuj zoo, kub tsis kam, kub tsis tshua muaj zog thiab txhua yam khoom; zoo kub ua haujlwm xws li stamping thiab dabtsi yog khoov, tsis muaj kev kho cua sov hardening tshwm sim (tsis yog-sib nqus, kev khiav hauj lwm kub - 196 degree ~ 800 degree), 304L muaj zoo heev tsis kam rau grain ciam corrosion tom qab vuam los yog tom qab kev nyuaj siab nyem; nws kuj muaj zoo corrosion kuj tsis muaj kev kho cua sov. Kev khiav hauj lwm kub yog -196 degree -800 degree .
Cov yam ntxwv ntawm 304L polished stainless hlau phaj muaj xws li zoo corrosion kuj, tshav kub tsis kam, kub tsis tshua muaj zog thiab mechanical zog, nrog rau zoo heev tsis kam mus rau grain ciam corrosion.
304L stainless hlau phaj yog universal stainless hlau khoom nrog zoo corrosion kuj, tshav kub tsis kam, tsis kub-siab zog, thiab txhua yam khoom. Nws kuj muaj qhov kub zoo ua haujlwm xws li stamping thiab dabtsi yog khoov, thiab tsis muaj qhov tshwm sim ntawm kev kho cua sov, yog li nws tsis yog hlau nplaum. Qhov kub ntau yog dav, los ntawm -196 degree C mus rau 800 degree C. Tshwj xeeb tshaj yog tsis muaj kev kho cua sov, 304L stainless hlau phaj tuaj yeem tswj tau zoo corrosion. Qhov no yog tshwj xeeb tshaj yog tshwm sim tom qab vuam los yog kev ntxhov siab nyem, thiab nws tsis kam mus rau grain ciam corrosion yog zoo heev. Qhov no ua rau 304L stainless hlau phaj dav siv nyob rau hauv cov teb xws li chemistry, thee, thiab roj av industries, xws li ua tshuab qhov chaw uas yuav tsum tau siab rau grain ciam corrosion kuj, lub tsev cov ntaub ntawv, tshav kub-resistant qhov chaw, thiab qhov chaw uas muaj teeb meem nyob rau hauv kev kho cua sov12.
Tsis tas li ntawd, cov yam ntxwv polishing ntawm 304L stainless hlau phaj kuj tsim nyog hais. Cov txheej txheem electrolytic polishing tuaj yeem ua rau cov xim sab hauv thiab sab nrauv ntawm 304L stainless hlau zoo ib yam, nrog cov luster ntev, haum rau polishing complex zoo li stainless hlau me me thiab cov khoom. Txoj kev no tsis tsuas yog txhim kho corrosion kuj ntawm qhov chaw, tab sis kuj tsis ua rau deformation nto. Nyob rau tib lub sijhawm, lub sijhawm polishing yog luv, thiab ntau lub workpieces tuaj yeem ua tiav ib txhij, txhim kho kev tsim khoom thiab
