ASTM A213 / ASME SA213Cov kev qhia tshwj xeeb npog cov npe seamless ferritic thiab ustenitic steel boiler, supertheater thiab cua sov sov.
TP321Stainless hlau yog cov khoom siv nrog cov khoom siv kub tau zoo tshaj plaws hauv cov huab cua zoo tshaj li 304 1} Siv cov khoom siv hluav taws xob zoo dua li 304
Anustenitic Stainless Hlau sib npaug rau hauv qib domestic 0cr18ni10ti 321 Vim yog qhov sib ntxiv ntawm cov hlau titanium, nws zoo tswj kev tsim ntawm chromium carbide.
TP321Austenitic Stainless hlau muaj zoo corrosion tsis kam nyob rau hauv cov huab cua thiab yog siv dav hauv Petrochemical, Fais thiab Kev Lag Luam Tsheb. Txawm li cas los xij, cov hlau "stainless hlau" tsis yog kiag li, vim qhov kev pabcuam tshwjxeeb, stainless hlau kuj tseem yuav corrosion. Kev nruab nrab, PH nqi, ntsuas kub thiab lwm yam yuav muaj ntau yam cuam tshuam rau kev xeb tawm ntawm cov hlau tsis xeb. Piv txwv li, hauv qhov rhiab kub ntau ntawm 450 ~ 850℃rau lub sijhawm ntev, stainless hlau yuav tshwm sim inngranular corrosion. Tus txheej txheem yog tias c muab nrog CR rau Ciam Suav los ua Cr23C6 thiab precipitates, yog li ntawd tias yog li ntawd-}}}}}}}}} hu ua "chromium tsis zoo". Lub Cria Cres yog ib qho ntawm cov ntsiab lus tseem ceeb rau inhibit intergranular corrosion, thaum muaj cov ntsiab lus ntawm cov kab ke ntawm cov corrosion yuav nce.
ASTM A213 Tp347Stainless hlau tshav kub hloov lub raj muaj cov kev kub ntxhov, muaj peev xwm ua kom zoo dua, thiab cov khoom siv kub ua kom zoo dua qub, thiab cov khoom siv hluav taws xob zoo heev, thiab yog cov khoom siv kub ua kom zoo dua qub
Txawm li cas los xij, nws yuav tsum tau sau tseg thaum siv tau tus nqi ntawm Astm A213 TPRAL yog siab dua, uas yuav ua rau muaj kev ntxhov siab ntau dua, thiab cov kev nkees nkees siab dua. Nyob rau tib lub sijhawm, cov thermal conductivity yog tsawg thiab cov thermal conductivity yog neeg pluag. Nws yuav tsum tsis txhob muaj cov kev daws teeb meem aque lossis chav dej ib puag ncig muaj cov tshuaj chloride muaj cov kev pheej hmoo ntawm cov tshuaj pleev xim chloride kev ntxhov siab. Cov txheej txheem vuam yuav tsum tau nruj me ntsis tswj tau kom txo qis kev nyiam ntawm thermal tawg.
Thaum xaiv cov leeg Tp347 lossis kev txiav txim siab ua kom muaj raws li cov leeg ua haujlwm tshwj xeeb Raws li tau hais los saum toj no, qhov sib txawv ntawm Tp347 thiab TPRA47H kev sib pauv tub sib pauv lus dag nkaus yog nyob rau hauv cov ntsiab lus carbon. Qhov txwv ntawm cov ntsiab lus carbon ntawm Tupbon Cov ntsiab lus ntawm Tp347 yog 0.08%, thiab "h" hauv Tp347 tus sawv rau qhov kub siab. Nws cov ntsiab lus carbon feem ntau yog 0.04% - 0.10%. Cov ntsiab lus carbon ntau dua tuaj yeem ua rau cov cua sov sib pauv ntawm lub zog kub ua ntej lub raj kub siab dua, uas tuaj yeem ua rau lub zog kub ua kom lub zog kub dua. Nws yog qhov tshwj xeeb tsim rau kev sib pauv cov leeg siv hauv qhov chaw kub nyob hauv ib puag ncig ntev.
