410s ishidi lensimbi engagqwali

Ingxubevange 410S (UNS S41008) ikhabhoni ephansi, ukuguqulwa okungaqini kwe-Alloy 410 (UNS S41000) injongo evamile 12% i-chromium martensitic insimbi engagqwali. Ikhabhoni ephansi kanye nokwengezwa kwealloy encane kunciphisa ukwakheka kwe-austenite emazingeni okushisa aphezulu okuvimbela ikhono lama-alloys ukuba lukhuni. I-410S ihlala ithambile futhi i-ductile ngisho nalapho ipholile ngokushesha ukusuka ngaphezu kwezinga lokushisa elibalulekile. Lesi sici esingaqinisi sisiza ukuvimbela ukuqhekeka lapho ingxubevange ivezwe emazingeni okushisa aphezulu noma ishiselwe. I-410S i-ferritic ngokuphelele esimweni sokuthunjwa. Ibonisa ukumelana nokugqwala okwanele okufana ne-410 kanye nokumelana okuhle kwe-oxidation.

Izinto Ezilinganayo

I-410S iyashunqiswa, noma ithambe, ukuze ingabi brittle. Lokhu kwenziwa ngokuyishisisa ifike phakathi kuka-1600 – 1650°F (871 – 899°C), bese ipholiswa ngomoya kancane endaweni efudumele ukuze iqede ukucindezeleka okubangelwa amakhaza. impahla, izinga lokushisa le-anneal kufanele lehliswe libe yibanga lika-1200 - 1350°F (649 – 732°C) ububanzi. Kodwa-ke, akufanele neze inyuswe ibe ngu-2000°F (1093°C) noma ngaphezulu ngenxa ye-embrittlement, okuwukulahlekelwa okuyingxenye noma okuphelele kwe-ductility yezinto, okuphambene nomphumela ofisayo wokudonsa i-410S.

Ngokumelana nokugqwala okuphezulu ezindaweni zamakhemikhali, indawo engu-410S kufanele ingabi nayo yonke i-tint yokushisa noma i-oxide eyakhiwe phakathi nenqubo yokuhoxisa noma eshisayo. Kubalulekile ukuthi yonke iminonjana ye-oxide ne-surface decarburization isuswe ngokubeka phansi noma ukupholisha zonke izindawo. Ngemva kwalokho, izingxenye zicwiliswa ku-10% kuya ku-20% wesisombululo se-nitric acid okulandelwa ukugeza kwamanzi. Lokhu okokuqinisekisa ukususwa kwanoma iyiphi i-Iron esele.

Ngemuva kwalesi sinyathelo, izingxenye zensimbi engagqwali ezingu-410S ngokuvamile zibhekwa njengezikwazi ukushiselwa ngamasu avamile okuhlanganiswa nezindlela zokumelana, nakuba ukunakwa okukhethekile kukhokhwa ukuze kugwenywe ukuphuka kwe-brittle weld ngesikhathi sokwenziwa kanye nokunciphisa ukungaqhubeki.

Umehluko omkhulu phakathi kwensimbi engagqwali 410 kanye ne-410S ukuthi i-410 iyisisekelo, inhloso evamile, insimbi engagqwali ye-martensitic engenziwa lukhuni kuyilapho i-410S iwukuguqulwa kweCarbon ephansi yensimbi engagqwali engu-410, eshiselwe kalula kodwa enezinto eziwumshini ezincishisiwe. I-410S insimbi engagqwali ingakhiwa kalula ngokudweba, ukuphotha, ukugoba, kanye nokwakhiwa kwamaroll.

izicelo ezisebenzisa i-410S Chromium ferritic insimbi engagqwali zikhule kakhulu eminyakeni yamuva nje ezimbonini zamakhemikhali kanye nezimboni zokuthutha zikawoyela noma igesi. Ukuhlolwa kokunquma amazinga okushisa okushintsha kwesigaba kuyaqhubeka ukuze kunqunywe izinga lokushisa lokuguqulwa kwe-alpha kuya ku-gamma kule alloy ezimweni zokupholisa ezihlukene. Imiphumela izonquma ukuthi i-410S ingasetshenziswa kanjani kangcono kulezi zimboni.
