Dab tsi yog v4a stainless hlau?
V4a stainless hlau yog qhov tsis sib nqus, ua kom sov thiab kuj muaj cov hlau txias. Nws yog ib qho yooj yim rau cov duab thiab txhuam, thiab tuaj yeem welded siv cov qauv txheem xws li tav thiab mag. Qhov kev sib ntxiv ntawm 2-2.5% Molybdenum muab cov dej qab zib zoo tshaj plaws hauv cov dej nrog cov dej ntsev thiab chlorides, ua kom zoo tshaj rau cov khoom siv marine thiab tshuaj lom neeg.
VİA COV KHOOM ZOO
Cov khoom sib npaug rau V4A yog tsuas yog AISI 316 / 316L stainless hlau, kuj tau paub los ntawm cov khoom ntiag tug 1.4404 (316L) lossis 1.4401 (316). Cov kab lus no sawv tawm rau lawv lub siab tiv thaiv rau corrosion thiab acids, ua tsaug rau ntxiv ntawm molybdenum thiab cov ntsiab lus ntawm chromium thiab npib tsib xee.
Cov qib kawm: V4A txuam nrog 1.4401, 1.440 thiab 1.4571, yog sib npaug rau Aisi 316L tus qauv.
Yog a4 tib yam li 316l?
Yog lawm, v4a yog German tsim rau cov hlau stainless uas feem ntau synonymous nrog 316L, ib feem ntawm Aisi 316 tsev neeg. Ob qho tib si yog cov zoo, corrosion-resistant chomium {}}}} molybdenum hlau siv siv hauv kev thov cov ntawv thov.

Qhov sib txawv ntawm v2a thiab v4a
V4A: Zoo corrosion tsis kam tshaj v2a ua tsaug rau Molybdenum, zoo tagnrho rau ib puag ncig txhoj xws li cov ntug dej hiav txwv lossis ze ntsev dej.
V2A (AISI 304): Haum rau cov ntawv thov sab hauv lossis tsawg dua, nrog cov txiaj ntsig zoo ntawm tus nqi qis.
V2A VS 304:
V2a thiab 304 yog tib yam khoom; Qhov sib txawv yog ib leeg ib qho kev sib cav sib ceg. V2A yog German tsim qauv rau Austenitic Steel sib paub hauv Tebchaws Meskas raws li 304 lossis AISI 304.
