Kusiyana Pakati pe316L ne304 Stainless Steel
Zvose316L uye 304ari austenitic Stainless steels anoshandiswa zvakanyanya mumaindasitiri, kuvaka, zvekurapa, uye zvine chekuita nechikafu. Nekudaro, ivo vanosiyana zvakanyanya munemakemikari anoumbwa, corrosion resistance, mechanical properties, uye mashandisirwo.
1. Kuumbwa Kwemakemikari
304 Stainless Simbi: Yakanyanya kuumbwa ne18% chromium (Cr) uye 8% nickel (Ni), ndosaka ichizivikanwawo se18-8 simbi isina tsvina.
316L Stainless Simbi: Rine16-18% chromium, 10-14% nickel, uye kuwedzera2-3% molybdenum (Mo), iyo inosimudzira kushorwa kwayo.
The"L" mu316Linomirirakabhoni yakaderera (≤0.03%), inovandudza weldability yayo uye kuderedza njodzi ye intergranular corrosion.
2. Corrosion Resistance
304 ine yakanaka corrosion resistance, yakakodzera kune zvakajairwa nharaunda uye kuratidzwa kune oxidizing acids.
316L inopa yakakwira corrosion kuramba, kunyanya muchloride-rich nharaunda(zvakadai semvura yegungwa nemhepo ine munyu), nekuda kwe molybdenum, iyo inobatsira kurambagomba uye mukororo ngura.
3. Mechanical Properties & Workability
304 yakasimba, nekuoma kuri pakati nepakati, zvichiita kuti zvive nyore kutonhora-kushanda, kukotama, uye weld.
316L haina kusimba zvishoma asi yakawanda ductile, ine yakaderera kabhoni yemukati inovandudzaweldability, zvichiita kuti zvive zvakanaka kune zvikumbiro apo post-weld heat treatment haigoneki.
4. Kuenzanisa Kwemari
316L inodhura kupfuura 304, kunyanya nekuda kwekukwira kwayo nickel uye molybdenum zvirimo, izvo zvinowedzera mutengo wekugadzira.
5. Zvikumbiro zvakakosha
| Feature | 304 Stainless Simbi | 316L Stainless Simbi |
|---|---|---|
| Corrosion Resistance | General resistance, yakakodzera kumamiriro ezuva nezuva | Superior corrosion resistance, yakanakira acidic, marine, uye chloride-rich nharaunda |
| Mechanical Simba | Simba repamusoro, nyore kushanda naro | Yakanyanya kuchinjika, yakanakira welding |
| Mutengo | More kutengeka | Zvimwe zvinodhura |
| Common Use | Furnicha, kitchenware, zvekushongedza zvivakwa | Zviridzwa zvekurapa, kugadzira chikafu, midziyo yemugungwa, mapaipi emakemikari |
Mhedziso
Kana application yako iri mu ageneral environment(zvakadai semidziyo yekubikira, zvekuvakisa, kana midziyo yemumba),304 isarudzo inodhura. Zvisinei, nokudanharaunda dzine ngura zvakanyanya(semvura yegungwa, kugadzirwa kwemakemikari, kana mishonga) kanaapo weldability yepamusoro inodiwa, 316L ndiyo sarudzo iri nani.
