409 430 439 441 443 ipuleti lensimbi engagqwali
Incazelo yokukhiqiza:
400 uchungechunge lwensimbi engagqwali ingxubevange yensimbi, ikhabhoni kanye chromium. Ngoba ayinayo i-nickel,
iyinsimbi engagqwali esindisa i-nickel, eyaziwa nangokuthi insimbi engagqwali. 400 uchungechunge insimbi engagqwali has evamile
izakhiwo kazibuthe ngenxa yesakhiwo sayo se-martensitic nensimbi.
400 uchungechunge lwensimbi engagqwali inokumelana okuqinile nokushisa okuphezulu kwe-oxidation, kanye nomzimba wayo kanye nemishini
izakhiwo ziba ngcono nakakhulu uma ziqhathaniswa ne-carbon steel. Iningi lama-stainless steels angu-400 angelashwa ngokushisa.

Isicelo:
1. 409 insimbi engagqwali : 409L inokumelana okuqinile kwezinga lokushisa eliphezulu, ingafinyelela injini esebenza kahle kakhulu futhi
i-exhaust system, futhi yehlise ubukhulu besistimu yokukhipha umoya, okunganciphisa ukukhishwa kwe-exhaust.
I-409L inezindleko eziphansi, ukuguquguquka okuhle, isivuno esikhulu nokushintshwa okulula. Ungumkhiqizo omusha ohambisana nemvelo.
2. 430 insimbi engagqwali: Okokuhlobisa ibhilidi, izingxenye zokushiswa kukaphethiloli, izinto zasendlini, izingxenye zikagesi zasendlini.
I-430F iyizinga lensimbi elinezinto zokusika zamahhala ezingezwe kunsimbi engu-430, esetshenziselwa ikakhulukazi ama-lathes azenzakalelayo, amabhawodi namantongomane.
3. 439 insimbi engagqwali: Ikheshi, amaphaneli okuhlobisa ezitebhisi ezizihambelayo; amaphaneli okuhlobisa ezakhiwo, njengezingxenye zesakhiwo sokuhlobisa,
amapayipi esakhiwo; Izingxenye zesistimu yokukhipha izimoto; umshini wokuwasha ubhavu wangaphakathi
4. 441 insimbi engagqwali: Exhaust manifold, ipayipi elingaphambili, I-CONVERTER, njll. yesistimu yokukhipha umoya wemoto.
5. 443 insimbi engagqwali: Insimbi engagqwali 443 iwuhlobo lwe-ferritic stainless steel. Ngokuvamile isetshenziselwa ukufaka esikhundleni se-304.
Ukumelana nokugqwala kwayo nokusebenza kokucubungula kubuthakathaka kune-304, kodwa intengo iphansi. Isetshenziswa kabanzi ku
izinto zikagesi, izitsha, izinto zasekhishini, amakheshi, ohhavini neminye imikhakha.
