Kev piav qhia
321 stainless hlau sawb yog ib hom austenitic stainless hlau uas muaj cov pa roj carbon tsawg thiab zoo corrosion kuj rau ntau qhov chaw corrosive.321 muaj qhov zoo tshaj plaws weldability, zoo machinability thiab zoo fabrication zog.
321 stainless hlau sawb feem ntau yog siv rau hauv kev lag luam chemical, pulp thiab ntawv kev lag luam, marine thiab offshore engineering industries nrog rau cov zaub mov thiab dej haus industries.
321 stainless hlau sawb kuj muaj qib siab ntawm kev tiv thaiv chloride kev nyuaj siab corrosion cracking thiab pitting.Nws kuj tseem tiv taus hydrochloric acid ntawm qhov kub siab txog 250 ° C (480 ° F).
Nta
Zoo Corrosion Resistance: 321 stainless hlau sawb muaj corrosion kuj zoo dua 304 thiab 316 hom stainless hlau, uas ua rau nws zoo tagnrho rau siv nyob rau hauv corrosive ib puag ncig.
Weldability zoo heev: 321 stainless hlau sawb tuaj yeem welded los ntawm txhua txoj kev suav nrog arc vuam (TIG / GTAW), electron beam vuam (EBW / EFW), submerged arc vuam (SAW) thiab laser beam vuam (LBIW).
Lub zog siab: Lub zog ntawm 321 stainless hlau sawb muaj txog li 50% siab dua li ntawm 304 hom stainless hlau thiab mus txog 80% siab dua li ntawm 316 hom stainless hlau vim lawv cov ntsiab lus carbon thiab austenite grain loj.
