Lub ntsiab tus neeg sawv cev qib ntawm ob lub tsev stainless steel yuav feem ntau muab faib ua plaub pawg:
1. Tsawg hlau hom - tus neeg sawv cev qib: UNS S32304 (23Cr-4Ni-0.1N)
2. Medium hlau hom - tus neeg sawv cev qib: UNS-S31803 (22Cr-5Ni) -3Mo-0.1N)
3. siab alloy hom - tus neeg sawv cev qib: UNS S32550 (22Cr-6Ni-3Mo-2Cu-0.2N)
4. super ob lub tsev stainless steel hom - txheem kawm qib: UNS-S32507 (25Cr-7Ni- 3.7Mo-0.3N).
Tsawg-hlau
UNS S32304 muaj tsis muaj molybdenum thiab yuav siv tau nyob rau hauv qhov chaw ntawm AISI304 los yog 316 rau kev nyuaj siab xeb kuj. Medium hlau hom: UNS S31803 muaj xeb kuj ntawm AISI316L thiab 6% Mo + N austenitic stainless steel; siab alloy hom: feem ntau muaj 25% Cr, kuj muaj molybdenum nitrogen, thiab ib co kuj muaj tooj liab phab ntsa hlau thiab tungsten, xws steel muaj ntau dua xeb kuj tshaj 22% Kr ob lub tsev stainless steel; super ob lub tsev stainless steel: muaj siab molybdenum thiab nitrogen, ib txhia kuj muaj tungsten thiab tooj liab, tseem haum rau hnyav xov xwm tej yam kev mob cv548, nrog zoo xeb kuj thiab txhua yam khoom, piv rau super austenitic stainless hlau.
