Kutheni i-Stainless Steel? Iimpawu eziphambili zokuvumela usetyenziso
Nokumelana Resistance
Uphawu olucacileyo lwentsimbi engagqwaliyo kukukwazi kwayo ukwenza umaleko we-chromium oxide ongazinyangiyo. Ifilimu enobukhulu obuyi-1-5 nanometer ikhusela isinyithi esingaphantsi kwi-oxidation. Le propati inezicelo kwiindawo zaselwandle kunye nokulungiswa kweekhemikhali kunye nokwakhiwa konxweme. Amanqanaba ahlukeneyo okumelana nokugqwala abonisa amanqanaba ahlukeneyo okhuseleko kuba I-304 insimbi engenasici Iyamelana nokuchatshazelwa ngumoya ngelixa i-316 stainless steel ikhusela ekuhlaselweni yi-chloride kwaye ii-duplex grades zibonelela ngokhuseleko kwiimeko ezimandundu zokusingqongileyo.
Amandla oomatshini
Intsimbi engagqwaliyo inika umlinganiselo ogqwesileyo wokuqina-ubunzima kuba amanqanaba okuqina kwemvula afana ne-17-4PH anika amandla okuvelisa ngaphezulu kwe-1,100 MPa. Amashishini okwakha kunye neendiza asebenzisa olu phawu lwezinto zokwakha kwizicelo zesakhiwo. Iinjineli zinokuphucula amandla amanqanaba e-austenitic ngokusebenza ngokubandayo kuba le nkqubo ivumela amandla okuqinisa uxinzelelo kwezi zinto.
Ubushushu bokusebenza
Iintsimbi ezingenasici zigcina iipropati zazo zoomatshini kuzo zonke iinqanaba zobushushu obugqithisileyo. Iinqanaba ze-austenitic zigcina ukuqina kwazo kumaqondo obushushu afikelela kwi--196°C. Iinqanaba zobushushu obuphezulu ezingama-309 kunye nama-310 zibonelela ngokumelana ne-oxidation okungaphezulu kwe-1,000°C kuzo zombini izixhobo ze-furnace kunye neenjini zejethi.

Uhlalutyo lweNdleko-yeNzuzo
I-304 grade isebenza njengesixhobo "esisebenzayo", esisetyenziswa ziinjineli malunga ne-70% yeeprojekthi kuba sibonelela ngentsebenzo ephakathi. Umsebenzisi kufuneka achithe iindleko zezinto ezingaphezulu ezingama-20 ukuya kuma-40 ekhulwini xa etshintsha ukusuka kwi-316 ukuya kwi-316 kodwa olu phuculo luphinda kabini ubomi benkonzo kwiindawo apho kukho i-chloride exposure.
Ukubeka iinkcukacha ezigqithisileyo kudlalisa imali ngaphandle kwenzuzo. Indawo yokugcina impahla ePhoenix echaza i-316 yerakhi yangaphakathi eyomileyo ihlawula amaxabiso aphezulu okumelana nokugqwala okubonelela ngexabiso eliphantsi. I-Ferritic 430 okanye intsimbi yekhabhoni epeyintiweyo iya kusebenza ngendlela efanayo ngexabiso eliphantsi.
Ukungacaciswanga kakuhle kwesakhiwo kubangela ukusilela okubiza kakhulu. Umenzi wedama lokuqubha eFlorida wonge i-30% echaza i-304 endaweni ye-316 yee-handrails ezikufutshane nolwandle, waza wahlawula i-400% engaphezulu xa kufuneka ukutshintshwa ngokupheleleyo emva kweenyanga ezili-18.
Ukuze ufumane isikhokelo esihambelana nebanga elithile, jonga I-304 insimbi engenasici kwizicelo ngokubanzi okanye I-316 insimbi engenasici kwindawo ezonakalisayo.
Izicelo Ezivelayo (2025-2030)
Iiteknoloji ezininzi ezintsha zibangela imfuno entsha yentsimbi engagqwaliyo ngaphaya kwezicelo zemveli.
