Dab tsi yog qhov sib txawv ntawm Sus304 thiab Sus304L?

Ntawm cov khoom siv stainless hlau stainless hlau, 304 stainless hlau phaj thiab 304L stainless hlau phaj yog ob hom dav hlau siv. Txawm hais tias lawv lub ntsiab lus tseem ceeb yog qhov zoo sib xws, muaj qhov sib txawv ntawm cov ntsiab lus carbon, corrosion tsis kam, cov khoom siv mechanical thiab cov chaw thov. Kab lus no yuav sib piv cov yam ntxwv ntawm ob daim hlau uas tsis siv no los pab cov neeg yuav txiav txim siab tsim nyog tshaj plaws thaum xaiv.

Lub ntsiab sib txawv ntawm sus304 thiab sus304L yog cov ntsiab lus carbon.
Tus "l" hauv sus3 {0 4l stainless hlau phaj sawv rau "cov pa roj carbon tsawg yog tsawg dua {}}. 03%. Cov ntsiab lus carbon ntawm sus304 feem ntau yog ib puag ncig 0.08%. Cov cuab yeej siv roj av tsawg ua rau Sus304L Stainless Hlau Txias Rolled phaj tsawg dua qub rau kev xaiv hauv cov xwm txheej uas vuam yog qhov yuav tsum tau ua. ‌

Corrosion Resistance sib piv

304L stainless hlau alloy phaj yog feem ntau zoo dua li 304 stainless hlau phaj nyob rau hauv cov nqe lus ntawm corrosion tsis kam vim nws cov ntsiab lus muaj roj carbon tsawg. Tshwj xeeb tshaj yog nyob rau hauv qhov kub lossis kub corrosive ib puag ncig, 304l kub-rolled portless stainless hlau daim phiaj thiab tuaj yeem zam kev corrosion (sensitization).
Lub ntsej muag tsis zoo yog hais txog qhov tseeb tias thaum stainless hlau yog rhuab rau morrosion-resistant tshuaj, txo nws corrosion tsis kam. 304L tau zoo nyob rau qhov tshwm sim ntawm qhov tshwm sim los ntawm txo cov ntsiab lus carbon, txuas ntxiv txhim kho nws cov corrosion tsis kam.

Lub zog thiab Hardness:
Vim yog cov ntsiab lus carbon qis, lub zog thiab hardness ntawm sus304L feem ntau qis dua sus304. Yog li ntawd, hauv cov ntawv thov raug rau kev kub siab lossis cuam tshuam, sus304 tuaj yeem tsim nyog dua.

Daim Ntawv Thov Kev Sib Piv
304 Stainless Hlau Phaj muaj kev ua tau zoo heev, tuaj yeem ua rau ntau yam duab los ntawm kev siv cov txheej txheem, thiab yuav tsis tsim cov qauv hlau txuas ntxiv. Nws yog tsim nyog rau ib puag ncig nrog ntsuas kub los ntawm -196 degree rau 800 degree.
304L stainless hlau phaj muaj kev tsis zoo rau intergranular corrosion thiab tuaj yeem ua haujlwm ruaj khov nyob rau hauv cov xwm txheej hnyav. Kev ua haujlwm kub ntau ntawm 304L tseem yog los ntawm -196 degree rau 800 degree.
