Yog tias koj tab tom sib piv SUS329J1 thiab SUS329J3L duplex stainless hlau rau corrosion-resistant lossis high-lub zog muaj kev siv, kev nkag siab txog lawv qhov sib txawv yog qhov tseem ceeb rau kev xaiv cov khoom zoo. Raws li tus kws tshaj lij stainless hlau xa khoom nrog ntau tshaj 18 xyoo ntawm kev xa tawm, GNEE muab SUS329J1 thiab SUS329J3L daim hlau, coils, raj thiab tuav nrog cov lus qhia ua tiav, nrog MTC 3.1/3.2 thiab EN / ASTM ntawv pov thawj, thiab xa khoom sai.
SUS329J1 yog dab tsi?
SUS329J1 yog austenitic-ferritic duplex stainless hlau uas ua raws li Japanese JIS tus qauv, uas yog raws li American tus qauv ASTM S32900, German tus qauv DIN 1.4460 thiab Suav teb chaws tus qauv 0Cr26Ni5Mo2 (S22608). Nws cov tshuaj muaj pes tsawg leeg muaj nyob nruab nrab ntawm 23.00% thiab 28.00% chromium, nruab nrab ntawm 3.00% thiab 6.00% npib tsib xee, nruab nrab ntawm 1.00% thiab 3.00% molybdenum thiab Tsawg dua lossis sib npaug rau 0.08% carbon. Cov khoom no raug rau kev kho mob ntawm 950-1100 degree, ua raws li kev ua kom txias sai, tsim kom muaj austenitic-ferritic duplex microstructure, uas nthuav tawm lub zog siab thiab corrosion kuj.
SUS329J3L stainless hlau yog dab tsi?
SUS329J3L (UNS S32205, S31803) yog austenitic -ferritic duplex stainless hlau nrog zoo heev corrosion kuj thiab lub zog zog. Piv nrog SUS316L thiab SUS317L, nws muaj kev tiv thaiv siab dua rau hauv cheeb tsam corrosion thiab tuaj yeem siv rau hauv cov khoom siv tshuaj, cov khoom siv seawater desalination, thiab lwm yam.
SUS329J1 Stainless Hlau vs SUS329J3L: Dab tsi yog qhov txawv?
Qhov sib txawv tseem ceeb ntawm SUS329J1 thiab SUS329J3L yog nyob rau hauv nws cov pa roj carbon tsawg thiab ntxiv cov ntsiab lus nitrogen, uas muab SUS329J3L ntau dua kev tiv thaiv corrosion (tshwj xeeb tshaj yog kev nyuaj siab corrosion cracking) thiab zoo weldability.

Qhov twg zoo dua, SUS329J1 lossis SUS329J3L?
SUS329J1 yog cov hlau tsis tshua muaj hlau duplex stainless hlau, paub txog nws lub zog thiab toughness nyob rau hauv ob qho tib si kub thiab tsis kub ib puag ncig; thaum SUS329J3L yog duplex stainless hlau nrog zoo heev corrosion kuj, tshwj xeeb tshaj yog pitting corrosion, crevice corrosion thiab kev nyuaj siab corrosion.
Puas yog SUS329J1 thiab SUS329J3L sib nqus?
Yog lawm, ob qho tib si SUS329J1 thiab SUS329J3L yog sib nqus rau qee qhov. Ob leeg yog duplex stainless hlau, txhais tau tias lawv muaj ib tug sib xyaw austenitic thiab ferritic qauv, ua rau lawv inherently sib nqus.
Daim ntawv thov
SUS329J1: Feem ntau siv rau ntau yam khoom uas xav tau lub zog siab thiab zoo corrosion kuj, tab sis tej zaum yuav xav tau cov txheej txheem ntxiv hauv kev siv vuam.
SUS329J3L: Vim nws zoo heev weldability thiab tsis kam mus rau chloride ib puag ncig, nws yog dav siv nyob rau hauv hnyav ib puag ncig xws li roj zoo pipelines, tshuaj lom neeg thauj nkoj, tshuaj cog khoom thiab seawater desalination nroj tsuag.
