1.4529 Stainless hlau yog dab tsi?

1.4529 stainless hlau, feem ntau hu ua Alloy 28 los yog UNS N08028, yog siab -kev ua tau zoo, molybdenum- txhim kho austenitic stainless hlau tsim los rau huab cua corrosion, tshwj xeeb tshaj yog nyob rau hauv sulfuric acid thiab chloride- muaj ib puag ncig. Nws feem ntau yog siv rau hauv kev ua tshuaj, kev tswj kev ua qias tuaj, thiab kev siv sab nrauv uas cov qhab nia zoo li 316L lossis 904L tsis txaus.

 

Qhov siab - qib kev ua tau zoo no yog tus qauv raws li cov qauv tseem ceeb thoob ntiaj teb.

Txuj	Qib sib npaug
EN (Tebchaws Europe)	1.4529
ASTM / AISI (USA)	Alloy 28, UNS N08028
Lub Npe	Alloy 28

Nws cov chromium siab, npib tsib xee, molybdenum, thiab cov ntsiab lus tooj liab muab kev tiv thaiv corrosion zoo heev.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4529 / Alloy 28

Zoo heev Acid Resistance:Tshwj xeeb tshaj yog tiv taus sulfuric acid thoob plaws ntau qhov ntau ntawm qhov kub thiab txias, nrog rau phosphoric, nitric, thiab organic acids.

High Chloride Resistance:Muaj kev tiv thaiv zoo rau pitting thiab crevice corrosion nyob rau hauv chloride-muaj ib puag ncig, nrog rau cov dej hiav txwv thiab dej brine.

Zoo Weldability thiab Formability:Yuav tau welded siv cov txheej txheem ntau thiab nthuav tawm cov ductility zoo rau kev ua haujlwm.

 

Cov ntawv thov tseem ceeb:

Kev ua tshuaj lom neeg:Reactors, kub exchangers, thiab piping rau sulfuric acid thiab lwm yam aggressive media.

Pollution Control:Scrubbers, ducts, thiab chimney liners nyob rau hauv flue gas desulfurization (FGD) systems.

Roj & Roj:Downhole tubing, wellhead Cheebtsam, thiab offshore platforms.

Pharmaceutical:Cov cuab yeej xav tau siab purity thiab tsis kam mus rau corrosive ntxuav cov neeg ua haujlwm.

 

Alloy 28 (1.4529) piv rau 904L (1.4539) li cas?
Ob leeg yog qib siab - alloy austenitic qib, tab sis Alloy 28 muaj cov qib siab dua ntawm chromium thiab npib tsib xee, thiab suav nrog tooj liab, muab nws ua haujlwm zoo tshaj rau sulfuric acid thiab zoo dua tag nrho kev ua haujlwm corrosion hauv cov kua qaub sib xyaw. Alloy 28 feem ntau raug xaiv rau cov mob hnyav dua qhov twg 904L yuav tsis muab kev tiv thaiv corrosion txaus, tshwj xeeb tshaj yog nyob rau hauv kev pabcuam sulfuric acid.

 

Dab tsi yog qhov kev txiav txim siab vuam rau Alloy 28 stainless hlau?
Vuam Alloy 28 yuav tsum sib phim lossis tshaj - alloyed muab tub lim, xws li Alloy 625 lossis siab dua -qib austenitic muab tub lim, kom muaj kev tiv thaiv corrosion hauv thaj tsam weld. Kev tswj cov cua sov tawm thiab cov roj tiv thaiv kom zoo (feem ntau argon-raws li) yog qhov tseem ceeb kom tsis txhob muaj qoob loo ntau dhau thiab nag lossis daus ntawm cov theem tsis zoo. Tom qab-vuam tu yog pom zoo kom rov qab kho corrosion.
