409 430 439 441 443 ipleyiti yensimbi engenasici
Inkcazo yemveliso:
I-400 series steel stainless steel i-alloy yentsimbi, i-carbon kunye ne-chromium. Ngenxa yokuba ayinayo i-nickel,
yintsimbi egcina i-nickel, ekwabizwa ngokuba yintsimbi engatyiwa. 400 series steel stainless inesiqhelo
iimpawu zemagneti ngenxa yesakhiwo sayo se-martensitic kunye nentsimbi.
Uluhlu lwe-400 lwensimbi engenasici lunokuxhathisa okuqinileyo kwi-oxidation yobushushu obuphezulu, kunye nomzimba kunye noomatshini
iipropati ziphuculwe ngakumbi xa kuthelekiswa nentsimbi yekhabhoni. Uninzi lweentsimbi ze-400 ze-stainless zingaphathwa ubushushu.

Isicelo:
1. 409 intsimbi engenastainless : 409L inokumelana nobushushu obuphezulu, inokufikelela kwi-injini esebenza ngokufanelekileyo kwaye
inkqubo yokukhupha, kunye nokunciphisa ubukhulu benkqubo yokukhupha, enokunciphisa ukukhutshwa kokukhupha.
I-409L inexabiso eliphantsi, ukuguquguquka okulungileyo, isivuno esiphezulu kunye nokutshintshwa okulula. Yimveliso entsha ehambelana nokusingqongileyo.
2. 430 steel stainless: Eyokuhombisa isakhiwo, iindawo zokutshisa amafutha, izixhobo zendlu, iinxalenye zesixhobo sendlu.
I-430F ibakala lensimbi kunye neepropati zokusika zamahhala ezongeziweyo kwi-430 yensimbi, esetyenziselwa kakhulu i-lathes ngokuzenzekelayo, iibholiti kunye namantongomane.
3. 439 intsimbi engatyiwa: I-elevator, iipaneli zokuhombisa ezizihambelayo; iipaneli zokuhombisa izakhiwo, ezifana neendawo zokuhombisa,
imibhobho yolwakhiwo; Amacandelo enkqubo yokukhupha iimoto; umatshini wokuhlamba ibhafu yangaphakathi
4. 441 intsimbi engaxutywanga: Exhaust manifold, umbhobho ongaphambili, I-CONVERTER, njl. ye-automobile exhaust system.
5. 443 intsimbi estainless: Stainless steel 443 luhlobo lwentsimbi engatyiwa yi-ferritic. Ngokuqhelekileyo isetyenziselwa ukutshintsha i-304.
Ukuxhathisa umhlwa kunye nokusebenza kokucubungula kubuthathaka kune-304, kodwa ixabiso liphantsi. Isetyenziswa ngokubanzi kwi
izixhobo zombane, izixhobo, izixhobo zasekhitshini, iilifti, ii-oveni kunye nezinye iindawo.
