Ikhabhoni yenye yezinto eziphambili zentsimbi yoshishino.Ukusebenza kunye nesakhiwo sensimbi kunqunywe kakhulu ngumxholo kunye nokusabalalisa kwekhabhoni kwintsimbi.Umphumo wekhabhoni ubaluleke kakhulu kwinsimbi engenasici.Impembelelo yekhabhoni kwisakhiwo sensimbi engenasici ibonakala ikakhulu kwiinkalo ezimbini.Kwelinye icala, ikhabhoni yinto ezinzisa iaustenite, kwaye isiphumo sikhulu (malunga namaxesha angama-30 enickel), kwelinye icala, ngenxa yobudlelwane obuphezulu bekhabhoni kunye nechromium.Enkulu, kunye nechromium - uchungechunge olunzima lwe-carbides.Ngoko ke, ngokwamandla kunye nokumelana nokubola, indima yekhabhoni kwinsimbi engenasici iyaphikisana.
Ukuqaphela umthetho wale mpembelelo, sinokukhetha iintsimbi ezingenasici kunye nomxholo wekhabhoni ohlukeneyo ngokusekelwe kwiimfuno ezahlukeneyo zokusetyenziswa.
Ngokomzekelo, umxholo we-chromium oqhelekileyo wamabakala amahlanu ensimbi ye-0Crl3 ~ 4Cr13, eyona nto isetyenziswa kakhulu kwi-industry kwaye incinci, ibekwe kwi-12 ~ 14%, oko kukuthi, izinto ezenziwe ngekhabhoni kunye ne-chromium i-chromium carbide zithathelwa ingqalelo.Injongo eqinisekileyo kukuba emva kokuba i-carbon kunye ne-chromium idibaniswe kwi-chromium carbide, umxholo we-chromium kwisisombululo esiqinileyo awuyi kuba ngaphantsi kwe-chromium encinci ye-11.7%.
Ngokubhekiselele kula mabakala amahlanu ensimbi achaphazelekayo, ngenxa yokwahluko kumxholo wekhabhoni, amandla kunye nokumelana nokubola kukwahluke.Ukuxhatshazwa kwe-corrosion ye-0Cr13 ~ 2Crl3 yensimbi ingcono kodwa amandla angaphantsi kune-3Crl3 kunye ne-4Cr13 yentsimbi.Isetyenziswa kakhulu ukwenza iinxalenye zesakhiwo.
Ngenxa yomxholo wekhabhoni ephezulu, amabakala amabini ensimbi anokufumana amandla aphezulu kwaye asetyenziswa kakhulu ekwenzeni imithombo, iimela kunye nezinye iindawo ezifuna amandla aphezulu kunye nokuxhatshazwa kokugqoka.Ngomnye umzekelo, ukuze unqobe i-intergranular corrosion ye-18-8 chromium-nickel steel stainless, umxholo wekhabhoni wensimbi ungancitshiswa ube ngaphantsi kwe-0.03%, okanye i-element (i-titanium okanye i-niobium) enobudlelwane obukhulu kune-chromium kunye nekhabhoni ingadityaniswa ukuyithintela ekwenzeni i-carbide.I-Chromium, umzekelo, xa ubunzima obuphezulu kunye nokumelana nokunxiba zizona zidingo eziphambili, sinokunyusa umxholo wekhabhoni wentsimbi ngelixa sinyusa umxholo we-chromium ngokufanelekileyo, ukuze sihlangabezane neemfuno zobunzima kunye nokumelana nokunxiba, kwaye sithathele ingqalelo ukuxhathisa okuthile kwe-Corrosion, ukusetyenziswa kwemizi-mveliso njengeebheringi, izixhobo zokulinganisa kunye neeblade ngentsimbi engenastainless 9Cr18 kunye ne-9 MoVC0Cr ephezulu njengentsimbi ye-9Cr18 kunye ne-9 MoVC0Cr 9 Cr5, nangona i-carbon content 9 Cr 9 Cr. %, ngenxa yokuba umxholo wabo wechromium nawo wonyuswe ngokufanelekileyo, ngoko ke isaqinisekisa ukuxhathisa ukubola.Funa.
Ngokuqhelekileyo, umxholo wekhabhoni weentsimbi ezingenasici ezisetyenziswa ngoku kwishishini uphantsi.Uninzi lweentsimbi ezingenasici zinomxholo wekhabhoni we-0.1 ukuya kwi-0.4%, kunye ne-asidi-resistant-resistant-resistant content content carbon ye-0.1 ukuya kwi-0.2%.Iinsimbi ezingenasici kunye nomxholo wekhabhoni omkhulu kune-0.4% zenza kuphela iqhekeza elincinci lenani elipheleleyo lamabakala, kuba phantsi kweemeko ezininzi zokusetyenziswa, iintsimbi ezingenasici zihlala zixhathisa ukubola njengenjongo yazo ephambili.Ukongezelela, umxholo wekhabhoni ophantsi ungenxa yeemfuno ezithile zenkqubo, ezifana ne-welding elula kunye ne-deformation ebandayo.
