904L stainless hlau yog qib siab alloy austenitic stainless hlau paub txog nws cov kev tiv thaiv zoo heev hauv ntau qhov chaw nruj heev. Nws muaj cov qib siab ntawm chromium, npib tsib xee, molybdenum, thiab tooj liab, uas ua rau nws ua tau zoo heev hauv cov kab mob corrosive.
1. Corrosion resistance: 904l cov khoom muaj kev tiv thaiv zoo rau ntau qhov chaw corrosive xws li sulfuric acid, phosphoric acid, chloride daws, thiab lwm yam tshuaj corrosive. Nws yog tshwj xeeb yog resistant rau pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking.
2. Cov ntsiab lus siab alloy: 1.4539 stainless hlau muaj cov ntsiab lus siab ntawm chromium (19-23 feem pua), npib tsib xee ({4}} feem pua), thiab molybdenum (4-5 feem pua). Qhov sib ntxiv ntawm tooj liab (1-2 feem pua ) ntxiv txhim kho corrosion kuj, tshwj xeeb tshaj yog txo cov acids xws li sulfuric acid.
904L stainless hlau muaj zoo heev corrosion kuj, thiab904l stainless hlau yeeb nkabyog dav siv nyob rau hauv ntau yam lag luam. Nws pom cov ntawv thov hauv cov chaw ua tshuaj lom neeg, cov chaw petrochemical, cov nroj tsuag desalination, chaw tsim tshuaj, kev lag luam pulp thiab ntawv, thiab offshore roj thiab roj ntau lawm. Nws kuj tseem siv tau rau hauv cov khoom siv hluav taws xob, cov kav dej, cov tso tsheb hlau luam, thiab lwm yam khoom siv raug rau qhov chaw corrosive.
