Yuav ua li cas yog corrosion kuj ntawm 1.4307?

1.4307 yog ib qho ultra- qis carbon austenitic stainless hlau. Nws qhov txiaj ntsig tseem ceeb yog nyob rau hauv nws qhov tshwj xeeb tiv thaiv rau intergranular corrosion; qhov tseem ceeb, nws tswj tau qib siab heev ntawm corrosion kuj txawm tias tom qab vuam, tsis tas yuav tsum tau kho cua sov tom qab. Nws zoo tiv thaiv corrosion nyob rau hauv feem ntau industrial thiab nroog atmospheric ib puag ncig, qeb duas raws li ib tug ntau stainless hlau nrog zoo heev corrosion kuj.

 

1.4307 stainless hlau pom zoo weldability

1.4307 stainless hlau yog tshwj xeeb tsim los ua kom tau qhov tshwj xeeb weldability, ua rau nws tshwj xeeb tshaj yog haum rau tuab - daim ntaub ntawv. Nws cov ntsiab lus tsis tshua muaj carbon tsawg (tsawg dua lossis sib npaug li 0.03%) txo qis cov nag lossis daus ntawm chromium carbides thaum vuam, yog li ua kom muaj kev tiv thaiv zoo heev rau intergranular corrosion tsis tas yuav tsum tau tom qab-weld heat treatment.

 

Machinability ntawm 1.4307 stainless hlau

1.4307 (AISI 304L) stainless hlau yog qis -carbon austenitic stainless hlau uas nthuav tawm nruab nrab mus rau kev ua haujlwm zoo. Vim nws qhov kev ua haujlwm tsawg- hardening nyiam, nws yooj yim dua los txiav dua tus qauv 304 stainless hlau; Txawm li cas los xij, txhawm rau tiv thaiv qhov tawv tawv, machining tseem yuav tsum tau siv cov cuab yeej ntse, tus nqi noj tsis tu ncua, thiab cov dej ntws siab ntawm cov kua txiav.

Puas yog 1.4307 stainless hlau sib nqus?

1.4307 (AISI 304L) stainless hlau tsis yog -sib nqus nyob rau hauv nws tus qauv annealed mob vim nws yog austenitic alloy. Txawm li cas los xij, nws tuaj yeem dhau los ua cov hlau nplaum me ntsis tom qab ua haujlwm txias (xws li kos duab lossis khoov) lossis vuam, vim tias cov txheej txheem no tuaj yeem ua rau muaj kev hloov pauv, ua rau nws qhov sib nqus permeability me ntsis.

Dab tsi yog qhov txawv ntawm 1.4307 thiab 1.4306 stainless hlau?

1.4306 (X2CrNi19-11) thiab 1.4307 (X2CrNi18-9) yog ob qho tib si qis-carbon, austenitic stainless hlau (304L hom) nrog zoo weldability. Thawj qhov sib txawv yog tias 1.4306 yog alloyed ntau dua, muaj ntau dua npib tsib xee thiab siab dua chromium me ntsis, uas ua rau muaj kev tiv thaiv corrosion zoo dua thiab cov khoom sib sib zog nqus zoo dua.
