409 430 439 441 443 saxan bir ah
Sharaxaada wax soo saarka:
400 taxane ahama birta waa daawaha birta, carbon iyo chromium. Sababtoo ah kuma jiraan nikkel
waa bir aan lahayn nikkel-badbaadinaysa, sidoo kale loo yaqaano birta aan lahayn. 400 taxane ahama birta ayaa caadi ah
sifooyinka magnetic sababtoo ah qaab-dhismeedka martensitic iyo birta.
400 taxane ahama birta ayaa iska caabin adag u leh oksaydhaynta heerkulka sare, iyo jireed iyo farsamo
guryaha ayaa la sii wanaajiyay marka la barbar dhigo birta kaarboon. Inta badan 400 ee birta ah ee taxan waxaa lagu daweyn karaa kulayl.

Codsiga:
1. 409 birta aan dahsoon: 409L waxay leedahay iska caabin heerkul sare oo xoog leh, waxay gaari kartaa matoor tayo sare leh iyo
habka qiiqa, iyo in la yareeyo dhumucda nidaamka qiiqa, taas oo yareyn karta qiiqa qiiqa.
409L waxay leedahay qiimo jaban, dabacsanaan wanaagsan, wax soo saar sare iyo bedel sahlan. Waa badeeco cusub oo deegaanka u wanaagsan.
2. 430 bir ah: Qurxinta dhismaha, qaybaha shidaalka gubta, qalabka guriga, qalabka guriga.
430F waa darajo bir ah oo leh sifooyin goyn bilaash ah oo lagu daray 430 bir ah, taas oo inta badan loo isticmaalo laashka tooska ah, boolasha iyo lowska.
3. 439 bir ah: wiish, dabaqyo qurxin oo kor u qaada; muraayadaha dhismaha ee qurxinta, sida qaybaha dhismaha ee qurxinta,
tuubooyinka dhismaha; Qaybaha nidaamka qiiqa baabuurta; weelka gudaha mashiinka dharka lagu dhaqdo
4. 441 bir aan-qabin: Gawaarida qiiqa, tuubada hore, BEDDELiyaha, iwm. ee nidaamka qiiqa baabuurta.
5. 443 bir aan daahin: Stainless steel 443 waa nooc ka mid ah birta aan dahsoon. Waxaa guud ahaan loo isticmaalaa in lagu beddelo 304.
Iska caabbinta miridhku iyo wax qabadkeeda ayaa ka daciifsan 304, laakiin qiimuhu wuu hooseeyaa. Waxaa si weyn loo isticmaalaa gudaha
qalabka korontada, maacuunta, qalabka jikada, wiishadaha, foornooyinka iyo meelaha kale.
