Thaum xaiv cov hlau tsis xeb rau kev siv hauv kev lag luam uas nyuaj, 316L thiab 904L yog ob qho kev xaiv nrov. Ob qho tib si muaj kev tiv thaiv xeb zoo heev thiab ruaj khov, tab sis lawv sib txawv ntau hauv kev sib xyaw, kev ua haujlwm kho tshuab, thiab tus nqi. Hauv tsab xov xwm no, peb piv 316L hlau tsis xeb thiab 904L hlau tsis xeb hla cov qauv tseem ceeb los pab koj xaiv cov hlau sib xyaw zoo rau koj qhov project.
316L Stainless Steel yog dab tsi?
316L stainless hlau yog ib qho qis-carbon version ntawm 316, ib feem ntawm tsev neeg austenitic stainless hlau. Nws muaj:
16–18% Chromium
10–14% Nickel
2–3% Molybdenum
Cov pa roj carbon tsawg (<0.03%)
Cov Khoom Tseem Ceeb ntawm 316L:
Kev tiv thaiv xeb zoo heev hauv cov dej hiav txwv thiab cov chaw muaj kua qaub nruab nrab.
Zoo weldability thiab formability.
Tiv taus kev xeb ntawm qhov tawg thiab qhov tawg.
Cov Ntawv Thov Feem Ntau:
Cov khoom siv khoom noj thiab tshuaj
Cov khoom siv hauv dej hiav txwv
Cov thoob tshuaj lom neeg thiab cov kav dej
Cov khoom siv hloov cua sov
904L Stainless Steel yog dab tsi?
904L stainless hlau yog ib hom hlau stainless hlau super austenitic uas muaj cov khoom sib xyaw siab, tsim tshwj xeeb rau kev tiv taus xeb heev. Nws suav nrog:
19–23% Chromium
23–28% Nickel
4–5% Molybdenum
1–2% Tooj Liab
Cov Khoom Tseem Ceeb ntawm 904L:
Kev tiv thaiv zoo rau cov kua qaub muaj zog (sulfuric, phosphoric).
Muaj kev tiv thaiv zoo rau kev tawg thiab kev ntxhov siab corrosion.
Tswj tau lub zog thiab kev tawv ntawm qhov kub siab.
Tsis yog hlau nplaum hauv txhua qhov xwm txheej.
Cov Ntawv Thov Feem Ntau:
Cov chaw ua kua qaub
Offshore thiab marine systems
Cov tshuaj reactors thiab tshuaj lom neeg
Cov khoom siv hloov cua sov uas siv cov khoom siv uas muaj zog heev
316L vs. 904L: Qhov Txawv Tseem Ceeb ntawm Ib Saib Ib Muag
| Vaj tse | 316L Stainless hlau | 904L Cov Hlau Stainless |
|---|---|---|
| Cov ntsiab lus ntawm npib tsib xee | 10–14% | 23–28% |
| Cov Ntsiab Lus Molybdenum | 2–3% | 4–5% |
| Kev Tiv Thaiv Kev Xeb | Zoo heev (dav dav thiab marine) | Zoo dua (acidic, chloride, dej hiav txwv) |
| Lub zog | Nruab nrab | Lub zog kho tshuab siab dua |
| Nqe | Kev lag luam pheej yig dua | Kim dua li qub |
| Kev coj cwj pwm sib nqus | Tsis yog hlau nplaum | Tsis yog hlau nplaum |
| Kev vuam tau | Zoo heev | Yuav tsum tau saib xyuas ntau dua thaum lub sijhawm vuam |
Koj Yuav Tsum Xaiv Qhov Twg?
Xaiv 316Lyog tias koj daim ntawv thov nyob rau hauv ib qhoib puag ncig corrosive nruab nrab, xws likev ua zaub mov, khoom siv kho mob, los yogcov qauv dej hiav txwvraug dej hiav txwv.
Xaiv 904Lraucov xwm txheej corrosive hnyav, tshwj xeeb tshaj yogcov kua qaub, cov chaw muaj chloride ntau, los yogcov chaw tsim tshuaj lom neeg thiab cov chaw ua haujlwm hauv hiav txwv.
Thaum 316L muaj qhov sib npaug zoo ntawm kev ua tau zoo thiab tus nqi,904L ua tau zoo duanyob rau hauv cov chaw ib puag ncig hnyav heev - ua rau nws yog qhov kev xaiv zoo tshaj plaws uas kev ntseeg siab mus sij hawm ntev yog qhov tseem ceeb.
Cov Kev Xav Kawg
Kev nkag siab txog qhov sib txawv ntawm 316L thiab 904L stainless hlau yog qhov tseem ceeb rau kev ua cov ntaub ntawv xaiv. Ntawm SAKY STEEL, peb muab ob qib hauv ntau yam ntaub ntawv xws li phaj, kauj, tuav, raj, thiab flanges - txhua yam ua raws li cov qauv thoob ntiaj teb xws li ASTM A240, A312, A182, thiab ntau dua.
