347 Stainless Hlau Square Tube
Cov tshuaj muaj pes tsawg leeg ntawm 347 stainless hlau suav nrog qib siab ntawm chromium (Cr) thiab npib tsib xee (Ni), nrog rau cov ntsiab lus ntxiv xws li titanium (Ti), carbon (C), thiab me me ntawm niobium (Nb). Lub xub ntiag ntawm niobium pab inhibit carbide nag lossis daus thiab txhim kho corrosion kuj.
347 stainless hlau tuaj yeem tsim cov yeeb yaj kiab oxide tuab ntawm qhov kub thiab txias, yog li tiv thaiv oxidative nres. Qhov no yog vim nws muaj ntau cov chromium, npib tsib xee, thiab ntxiv cov titanium thiab lwm yam khoom. Oxide zaj duab xis yog cov khoom tiv thaiv uas tuaj yeem thaiv kev sib cuag ncaj qha ntawm oxygen thiab hlau, thiab ua lub luag haujlwm hauv kev ncua lossis inhibiting oxidation ntawm hlau. Yog li, 347 stainless hlau tseem tuaj yeem tswj tau qhov zoo thiab ua haujlwm ntawm qhov kub siab dua, yog li txhim kho nws lub neej kev pab cuam.
Stainless hlau 347 muaj zoo heev corrosion kuj thiab ua tau zoo tshwj xeeb tshaj yog nyob rau hauv ib tug ntau yam ntawm corrosive xov xwm. Qhov zoo ntawm nws cov corrosion kuj yog los ntawm cov hauv qab no:
Titanium inhibition: Qhov sib ntxiv ntawm titanium (Ti) lub caij tuaj yeem tiv thaiv carbide nag lossis daus, txo cov kev cuam tshuam ntawm intergranular thiab corrosion tsis kam.
Cov ntsiab lus siab chromium thiab npib tsib xee: Cov ntsiab lus siab chromium thiab npib tsib xee ntawm 347 stainless hlau muab nws zoo corrosion kuj, ua kom nws tiv thaiv corrosion hauv ntau yam tshuaj lom neeg.

Lub tuam txhab kom zoo dua
Cov txiaj ntsig tseem ceeb ntawm gnee tuam txhab dag nyob rau hauv nws cov nplai ntau lawm, ntau cov khoom siv raw, cov cuab yeej tsim khoom siab heev, cov txheej txheem ntau lawm thiab cov neeg ua haujlwm paub txog. Cov ntsiab lus no ua rau nws ua tau zoo tsim cov khoom siv hlau zoo thaum muab cov kev daws teeb meem los ua kom tau raws li cov kev xav tau ntawm kev lag luam, nyob twj ywm kev sib tw, thiab tuav txoj haujlwm tseem ceeb hauv kev lag luam.
Neeg tuaj xyuas
Raws li cov khoom siv yooj yim, steel yog siv dav hauv kev tsim kho, tsim khoom, tsheb, nkoj, tsheb ciav hlau thiab lwm yam. Qhov kev thov rau cov hlau hauv cov cheeb tsam no yog qhov ruaj khov, muab lub tuam txhab nrog kev lag luam txhim khu kev qha.
