Wershada ugu iibinta fiican 430 Birta birta ah - QN1803 (304D)
Warshada ugu iibka badan 430 Birta aan-Aabaha lahayn - QN1803 (304D) Saxan bir-la'aan ah - Faahfaahinta Huaxin:
1. Sharaxaada:
Heerka badeecada cusub ee QN1803 waa nitrogen-kii ugu horreeyay ee adduunka ugu sarreeya, iska caabbinta daxalka sare, nikkel-badbaadinta austenitic ahama alaabada.
Iyada oo ku saleysan hubinta iska caabbinta daxalka u dhiganta 304 birta ah, xoogga maaddada ayaa la wanaajiyey, iyo walxaha
qiimaha waa la dhimay, taas oo ka dhigaysa mid qiimo jaban oo ka tartan badan suuqa in ka badan 304 bir ah.
Tilmaamaha naqshadaynta wax soo saarka cusub: nitrogen sare (≥2000ppm), chromium sare (≥18%), nikkel dhexdhexaad ah (~ 3.0%) iyo naxaas sare (≥1.5%).
Iyada oo loo marayo qalabka R&D dhijitaalka ah ee Thermo-Calc thermodynamic jaantus xisaabinta software-ka iyo falanqaynta xogta tijaabada ah, hagaajinta
walxaha alloying ee qayb kasta oo ka mid ah qayb kasta ma aha oo kaliya hagaajinaysaa iska caabinta daxalka ee alaabta, laakiin sidoo kale ka dhigaysa xoogga wax soo saarka ee QN1803
in ka badan 1.3 jeer 304.
QN1803 waxay leedahay sifooyinka soo socda:
1) Daxalka daxalka u dhigma PREN=Cr+3.3Mo+30N-Mn waxa uu ka sarreeyaa 19.0, kaas oo leh ugu yaraan iska caabbinta daxalka ee 304
Bir daxal laheyn.
2) iska caabbinta daxalka isku midka ah ee lagu daro hydrochloric acid, milo sulfuric acid, acetic acid + milix iyo deegaan kale ayaa aad uga fiican
304 bir ah.
3) caabbinta daxalka ayaa ka fiican 304 ee gobolka isticmaalka dhabta ah ka dib foorarsiga, shaabadeynta, xaalad adag iyo samaynta qabow kale.
4) xoogga wax-soo-saarku wuxuu ka badan yahay 1.3 jeer in ka badan 304 birta ah, waxayna leedahay dherer aan ka yarayn 45%. Xiro iska caabin iyo
waxqabadka daalku way ka fiican yihiin 304 birta ah.
5) waxqabadka alxanka wanaagsan, xoogga alxanka ka dib waa ka sarreeyaa in 304 ahama, iyo iska caabin daxalka waa.
oo la barbardhigi kara 304 bir ah.
