Ntev raug rau ntsev / chlorides. Ob leeg yog cov khoom noj- qib stainless hlau, tab sis kev tiv thaiv ntxiv ntawm 316 stainless hlau tiv thaiv pitting thiab kev ntxhov siab corrosion tawg, ua kom lub neej ntev dua nyob rau hauv cov xwm txheej hnyav.
Puas yog 304 stainless hlau zoo dua rau khaws cov dej haus dua li 316 stainless hlau?
Cov qib zoo tshaj plaws ntawm stainless hlau nyob ntawm koj cov kev xav tau: 316 stainless hlau muaj qhov zoo tshaj plaws corrosion kuj thiab yog qhov zoo tshaj plaws nyob rau hauv ib puag ncig hnyav; 304 stainless hlau yog tus nqi tsim nyog thiab ruaj khov; thaum 201 stainless hlau yog pheej yig tab sis tsis muaj xeb kuj. Kuv xav qhia kuv qhov kev paub ua ntau txhiab lub fwj dej.
Dab tsi yog 304 Stainless Hlau?
304 stainless hlau yog austenitic stainless hlau uas muaj 18% chromium thiab 8% npib tsib xee, tseem hu ua "18-8" 304 stainless hlau. Nws yog renowned rau nws cov khoom zoo heev, xws li siab corrosion kuj, superior durability, thiab versatility, thiab yog dav siv nyob rau hauv ntau yam khoom, nrog rau cov khoom siv hauv chav ua noj, cov cuab yeej ua zaub mov, thiab cov ntawv thov kev lag luam.
Dab tsi yog 316 Stainless Hlau?
316 stainless hlau yog austenitic stainless hlau uas muaj 16-18% chromium, 10-14% nickel, thiab 2-3% molybdenum. Lub xub ntiag ntawm molybdenum txhim kho nws cov kev tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj chloride thiab acidic, ua rau nws haum rau siv nyob rau hauv lub nkoj tsim, tshuaj, thiab zaub mov kev lag luam.
Cov tshuaj muaj pes tsawg leeg ntawm 304 stainless hlau thiab 316 stainless hlau
| Qib | C | Si | Mn | P | S | N | Cr | Ni | Mo |
|---|---|---|---|---|---|---|---|---|---|
| 304 | 0.07 | 1.00 | 2.00 | 0.045 | 0.015 | 0.10 | 17.5 - 19.5 | 8.0 - 10.5 | - |

Corrosion Resistance
304 Stainless hlau
304 stainless hlau muaj kev nyab xeeb rau kev sib cuag nrog cov khoom noj thiab dej haus feem ntau, ua kom cov zaub mov - qib kev nyab xeeb, thiab muaj kev tiv thaiv corrosion txaus ntawm tus nqi qis dua qib siab dua - qib stainless hlau.
Nws tiv taus feem ntau oxidizing acids thiab yuav tsis xeb nyob rau hauv cov zaub mov ua ib puag ncig.
Txawm li cas los xij, 304 stainless hlau yog qhov yooj yim rau pitting corrosion vim muaj cov chlorides, ua rau nws tsis tsim nyog siv hauv dej ntsev lossis siab - dej qab ntsev.
316 Stainless hlau
316 stainless hlau tuav nws txoj kev tiv thaiv corrosion txawm tias kub kub thaum lub sijhawm ua zaub mov thiab kev lag luam.
316 stainless hlau yog qhov zoo tagnrho rau kev lag luam nqaij nruab deg lossis siv cov khoom siv acidic xws li txiv kab ntxwv lossis txiv lws suav.
Yog li ntawd, vim nws qhov kev tiv thaiv corrosion zoo dua, 316 stainless hlau yog qhov kev xaiv zoo dua rau cov dej ntsev lossis cov kua qaub.
Kub Resistance ntawm 304 thiab 316 Stainless hlau
304 Stainless Hlau: 304 stainless hlau ua haujlwm ruaj khov ntawm qhov kub txog li 870℃(1600℃F), ua rau nws tsim nyog rau feem ntau ua noj thiab cua sov- ua cov ntawv thov. Nws tsis yog yooj yim deformed ntawm qhov kub thiab txias, tab sis ntev raug tshaj qhov kub ntawm qhov no yuav cuam tshuam rau nws cov qauv kev ncaj ncees.
316 Stainless Hlau: 316 stainless hlau yog qhov zoo dua li 304 stainless hlau hauv kev tuav qhov kub thiab txias. Nws tuav nws lub zog thiab kev tiv thaiv corrosion txawm tias tom qab lub sijhawm ntev raug rau qhov kub thiab txias, tsis tshua muaj kub, lossis rov ua dua kub hloov. Yog li ntawd, nws yog qhov zoo tagnrho rau kev ua kom tsis muaj menyuam, khov, thiab cov khoom siv uas xav tau cua sov thiab cua txias.
Yam hom stainless hlau koj yuav tsum xaiv rau kev ua zaub mov?
Yog tias koj ua cov khoom xyaw me me, cov ntsev me me, thiab tsuas yog xav tau kev tu txhua hnub, ces 304 stainless hlau yog qhov kev xaiv zoo, muab cov txiaj ntsig zoo rau cov nyiaj.
Yog tias koj xav tau cov khoom noj qab ntsev, marinades, cov khoom xyaw acidic, lossis siv cov tshuaj tua kab mob muaj zog, ces 316 stainless hlau yog qhov kev xaiv zoo dua vim tias nws tiv thaiv corrosion thiab kev laus. Txawm hais tias nws kim dua, nws muaj lub neej ntev dua.
