Dab tsi yog 1.4301 stainless hlau?
Hom 304 thiab 304L stainless hlau tseem hu ua 1.4301 thiab 1.4307, feem. Hom 304 stainless hlau yog qhov ntau tshaj plaws thiab siv dav. Nws yog qee zaum tseem hu los ntawm nws lub npe qub 18/8, uas los ntawm nws cov nomall comprosition ntawm 18% chromium thiab 8% npib tsib xee.
1. Txheej txheem cej luam ntawm stainless hlau 1.4301 thiab 1.4307
Ob qho tib si en 1.4301 thiab En 1.4307 zwm rau cov neeg siv tsis tau lub zog ntawm tsev neeg thiab yog sib npaug rau AISI 304 thiab AISI 304L, feem.
Cov ntsiab lus tseem ceeb ntawm cov lus dag hauv cov ntsiab lus carbon:
1.4301 (304) muaj cov ntsiab lus carbon ntau ntawm 0.07%
1.4307 (304l) muaj cov ntsiab lus carbon ntau ntawm 0.03%
Qhov kev sib hloov no me me cuam tshuam cuam tshuam rau weldability thiab kuj mus rau intergranular corrosion.

Yog 1.4307 tsis muaj zog tshaj li 1.4301?
Yog lawm, me ntsis. 1.4307 tau qis dua lub zog thiab tawm los ntawm nws cov ntsiab lus cov roj carbon, tab sis tseem ua tau raws li cov kev siv rau feem ntau.
Kuv puas tuaj yeem siv 1.4301 hloov ntawm 1.4307 rau Welded qauv?
Yog lawm, tab sis tom qab kev kho cua sov los yog siv hluav taws xob tshav kub lossis siv yuav tsum tau kho kom haum corrosion yog tias 1.4301 yog siv hauv vuam.
Yog 1.4301 thiab 1.4307 txuas ntxiv hauv cov ntawv thov hu rau zaub mov noj?
Yog lawm. Ob qho tib si muaj kev nyab xeeb rau kev tiv tauj cov zaub mov, tab sis 1.4307 yog nyiam rau welded cov khoom noj khoom noj vim nws cov weldability zoo dua.
Uas muaj txiaj ntsig ntau dua?
Feem ntau, 1.4301 yog me ntsis pheej yig dua vim nws cov txiaj ntsig roj carbon ntau dua thiab muaj zog me ntsis. Txawm li cas los xij, rau Welded qauv, tus nqi tswj kev lag luam ntev ntawm 1.4307 yuav qis dua.
Vim li cas thiaj xaiv peb?
