I-Stainless Steel 321/321H Amapuleti Amashidi

I-alloy 321 (UNS S32100) iyipuleti lensimbi engagqwali elizinzile elinikeza njengenzuzo enkulu ukumelana nokugqwala kwe-intergranular kulandela ukuchayeka emazingeni okushisa ebangeni lemvula ye-chromium carbide ukusuka ku-800 kuya ku-1500°F (427 kuya ku-816°C). I-alloy 321 ipuleti lensimbi engagqwali lizinzile ngokumelene nokwakheka kwe-chromium carbide ngokungezwa kwe-titanium.

I-alloy 321 ipuleti lensimbi engagqwali nayo inenzuzo ensizakalweni yokushisa okuphezulu ngenxa yezakhiwo zayo ezinhle zemishini. I-alloy 321 insimbi engagqwali ipuleti linikeza izakhiwo ezikhuphukayo nezikhuphuka ingcindezi kune-Alloy 304 futhi, ikakhulukazi, i-Alloy 304L, engase futhi icatshangelwe ukuchayeka lapho ukuzwela nokugqwala kwe-intergranular kuwukukhathazeka.

Ukuhleleka
Uhlobo 321 lungakhiwa kalula futhi ludonswe, nokho, izingcindezi eziphezulu ziyadingeka futhi kutholwa i-springback eningi kune-carbon steel nezinsimbi ezingenasici ze-ferritic. Njengezinye izinsimbi ezingenasici ze-austenitic, uHlobo lwama-321 luba lukhuni ngokushesha futhi lungase ludinge ukukhishwa ngemva kokwakheka okuqinile.Ukuba khona kwezinto ezithile ezihlanganisiwe kungenza uhlobo 321 lube nzima kakhulu ukulwenza kunamanye amamaki e-austenitic afana no-301, 304 kanye no-305.

Ukwelashwa Kokushisa
Uhlobo 321 aluqiniseki ngokulungiswa kokushisa.I-Annealing: Shisisa ufike ku-1750 - 2050 °F (954 - 1121°C), bese ucisha amanzi noma uphole emoyeni.

Ukushisela
Isigaba se-austenitic sezinsimbi ezingagqwali ngokuvamile sithathwa njengokushisela ngamasu avamile wokuhlanganisa kanye nokumelana. Kudingeka ukucatshangelwa okukhethekile ukuze ugweme ukushisela "ukuqhekeka okushisayo" ngokuqinisekisa ukwakheka kwe-ferrite ku-weld deposit. Le ngxubevange ethile ngokuvamile ibhekwa njengokushisela okuqhathaniswa nohlobo 304 no-304L. Umehluko omkhulu ukwengezwa kwe-titanium okunciphisa noma okuvimbela imvula ye-carbide ngesikhathi sokushisela. Uma isicwenga se-weld sidingeka, i-AWS E/ER 347 noma i-E/ER 321 ivame ukucaciswa.Uhlobo 321 lwaziwa kakhulu ezincwadini eziyizithenjwa futhi ulwazi olwengeziwe lungatholakala ngale ndlela.
