Thaum xaiv stainless hlau rau kev thov kev lag luam, 316L thiab 904L yog ob qho kev xaiv nrov. Ob qho tib si muaj kev tiv thaiv corrosion zoo thiab ua haujlwm ntev, tab sis lawv txawv qhov sib txawv, kev ua haujlwm zoo, thiab tus nqi. Hauv tsab xov xwm no, peb piv 316L stainless hlau thiab 904L stainless hlau hla cov qauv tseem ceeb los pab koj xaiv cov hlau zoo rau koj qhov project.
316L Stainless hlau yog dab tsi?
316L stainless hlau yog ib qho qis-carbon version ntawm 316, ib feem ntawm austenitic stainless hlau tsev neeg. Nws muaj:
16-18% Chromium
10-14% Nickel yog '
2-3% Molybdenum
Cov pa roj carbon tsawg (<0.03%)
Cov khoom tseem ceeb ntawm 316L:
Zoo heev corrosion kuj nyob rau hauv marine thiab nruab nrab acidic ib puag ncig.
Zoo weldability thiab formability.
Resistant rau pitting thiab crevice corrosion.
Kev siv ntau:
Khoom noj khoom haus thiab tshuaj
Marine Cheebtsam
Chemical tanks thiab kav dej
Thaum tshav kub kub exchangers
904L Stainless hlau yog dab tsi?
904L stainless hlau yog super austenitic stainless hlau nrog cov ntsiab lus siab alloy, tshwj xeeb tsim rau huab cua corrosion kuj. Nws suav nrog:
19-23% Chromium
23-28% npib tsib xee
4-5% Molybdenum
1-2% tooj liab
Cov khoom tseem ceeb ntawm 904L:
Superior tsis kam rau cov acids muaj zog (sulfuric, phosphoric).
Siab tiv taus pitting thiab kev nyuaj siab corrosion cracking.
Khaws lub zog thiab toughness ntawm qhov kub thiab txias.
Tsis-magnetic nyob rau hauv tag nrho cov mob.
Kev siv ntau:
Acid processing nroj tsuag
Offshore thiab marine systems
Pharmaceutical thiab chemical reactors
Thaum tshav kub kub exchangers tuav cov xov xwm txhoj puab heev
316L vs. 904L: Qhov txawv ntawm qhov tseem ceeb ntawm ib sab
| Khoom | 316L Stainless hlau | 904L Stainless hlau |
|---|---|---|
| Cov ntsiab lus Nickel | 10-14% | 23-28% |
| Molybdenum Cov ntsiab lus | 2-3% | 4-5% |
| Corrosion Resistance | Zoo heev (General thiab marine) | Superior (acidic, chloride, dej hiav txwv) |
| Lub zog | Nruab nrab | Lub zog siv tshuab siab dua |
| Nqe | Kev lag luam ntau dua | Tus nqi kim dua |
| Sib nqus cwj pwm | Tsis-magnetic | Tsis-magnetic |
| Weldability | Zoo heev | Yuav tsum tau saib xyuas ntau dua thaum vuam |
Koj yuav tsum xaiv qhov twg?
Xaiv 316Lyog tias koj daim ntawv thov nyob hauv anruab nrab corrosive ib puag ncig, zoo likev ua zaub mov, khoom siv kho mob, los yogmarine structuresraug dej hiav txwv.
xaiv 904lrautxhoj puab heev corrosive tej yam kev mob, tshwj xeebacidic media, chloride nplua nuj ib puag ncig, los yoghigh-end tshuaj thiab offshore installations.
Thaum 316L muaj qhov sib npaug zoo ntawm kev ua tau zoo thiab tus nqi,904l zoonyob rau hauv ib puag ncig huab - ua rau nws yog qhov kev xaiv zoo tshaj qhov kev ntseeg tau ntev ntev yog qhov tseem ceeb.
Kev xav zaum kawg
Nkag siab txog qhov sib txawv ntawm 316L thiab 904L stainless hlau yog qhov tseem ceeb rau kev xaiv cov ntaub ntawv paub. Ntawm SAKY STEEL, peb muab ob qib hauv ntau hom ntawv suav nrog cov phaj, coils, tuav, raj, thiab flanges - tag nrho ua raws li cov qauv thoob ntiaj teb xws li ASTM A240, A312, A182, thiab ntau dua.
