304 vs sus316: 20% tus nqi sib txawv, uas yog qhov haum rau koj qhov project?

304 vs sus316 Stainless hlau: 20% tus nqi sib txawv, yuav ua li cas yuav xaiv cov neeg yuav xaiv?

Hauv kev txheeb xyuas ntawm cov kev xav ntawm cov tshuaj sib xyaw ua ke, corrosion tsis kam, muaj kub ua tsis kam, thiab kev ua tau zoo!

304 vs sus316 stainless hlau tshuaj lom neeg:

304 vs sus316 corrosion Kuj:
Neutral ib puag ncig (huab cua / kais dej): Ob leeg ua tau zoo, 304 yog txaus kom tau raws li kev xav tau txhua hnub.
Chloride ion ib puag ncig (dej hiav txwv / ntsev dej / da dej pas dej da):
304: Pitting pib tshwm sim tom qab 200 teev, thiab xeb xeb tshwm sim tom qab 1 xyoo;
Sus316: Tsis muaj qhov pom tseeb corrosion tom qab 1000 teev, thiab qhov chaw nyob seem tau txais ntau dua 3 xyoos (ntsuas cov ntaub ntawv: nace TM0177 txuj ci).
Acid thiab ib puag ncig Alkali ib puag ncig (xws li 10% sulfuric acid / hydrochloric acid):
304: Tsuas tuaj yeem tiv taus 24 teev ntawm 20 degree;
Sus316: tuaj yeem mob siab rau ntau tshaj 72 teev nyob rau hauv tib qho kev mob, thiab cov corrosion tsis kam yog nce los ntawm 50% thaum kev nkag siab tsawg dua lossis sib npaug rau 5%.

304 vs sus316 siab tsis kam:
Chav tsev kub txog 500 degree: lub zog ntawm ob yog zoo sib xws, thiab 304 muaj txiaj ntsig zoo dua;
{{0 {0}} degree: 304 pib ua kom pom tseeb oxide nplai, thiab oxidation tus nqi ntawm sus316 yog txo los ntawm 40%;
Saum toj no 800 degree: 304 nplej: 304 nplej tau coarsen sai sai, thiab sus316 tuaj yeem tiv siab luv luv ntawm 1200 degree (xws li boiler Superhterios).

304 vs sus316 Cov Khoom Siv Neeg Kho Tshuab:
Lub zog tensile: ntau dua los yog sib npaug rau 515MPA, lub rooj sib tham cov kev xav tau ntawm cov qauv txheej txheem feem ntau;
Kev siv vuam: 304 vuam tsis xav tau kev pab tshwj xeeb, sus316 yuav tsum molybdenum-xws li ER316L), thiab cov kuab tshuaj kho kom raug pom zoo tom qab vuam;
Kev Tsim Kho No: 304 yog yooj yim rau daim ntawv, thiab sus316 xav tswj qhov deformation ntawm tsawg dua lossis sib npaug rau 15% thaum tab tom ua kom tsis txhob tawg.

304 vs sus316 them lub voj voog:
Cov nqi yuav khoom: Sus316 yog 20% ​​{2}}% ntau dua 304 (noj φ57} 3mm 6}} Yuan ib meter);
Tus nqi kho: hauv marine engineering, 304 lub sampelines yuav tsum tau los tiv thaiv corrosion tu txhua xyoo (thaum sus316 tuaj yeem yog tus txij nkawm-dawb rau 5 xyoos;
Hloov tus nqi: Qhov nruab nrab lub neej ntawm 304 hauv cov cuab yeej siv tshuaj lom neeg yog {}}}}}} tus nqi yog txo los ntawm 40%.

 

Kev yuav Didfall Kev Zam Txim: 3 cov ntsiab lus txiav txim siab ntev cov txiaj ntsig
Saib ntawm txoj kev siv cov qauv: 304 xav kom paub meej tias nws yog GB / t} (}} (}} kom tsis txhob muaj cov khoom lag luam tsawg dua 6%);
Sus316 xav tau txheeb xyuas seb cov ntsiab lus Molybdenum yog ntau dua lossis sib npaug nrog 26L rau impersonate, thiab molybdenum cov ntsiab lus tsuas yog 1.8%).
Cov kev kho deg:
Rau cov zaub mov-qib scenes, ro-roughness ra tsawg dua los yog sib npaug}. 8μm), thiab rau kev xaiv tshuaj lom neeg (tshem tawm vuam oxide nplai).
Cov ntaub ntawv zoo siab ua tau zoo yog tsim nyog:
Daim ntawv pov thawj khoom (yuav tsum muaj C, CR, NI, Mo keeb ntsiab lus);
Cov Kev Ntsuas Cov Kws Tshaj Qhia Kev Xeem Txuj Ci (ASTM A262 Txuj Ci E, Sus316 yuav tsum dhau).
