904L Stainless hlau Square yeeb nkab

Corrosion Resistance

904L stainless hlau muaj npe nrov rau nws qhov tshwj xeeb corrosion-resistant zog. Nws muaj feem ntau ntawm chromium (19 - 23%), nickel (23 - 28%), thiab molybdenum (4 - 5%). Cov ntsiab lus chromium tsim ib txheej oxide passive nyob rau saum npoo ntawm cov yeeb nkab, uas ua raws li kev tiv thaiv corrosive. Qhov sib ntxiv ntawm npib tsib xee thiab molybdenum ntxiv txhim kho nws cov kev tiv thaiv rau pitting corrosion, crevice corrosion, thiab kev ntxhov siab - corrosion cracking. Piv txwv li, nyob rau hauv cov tshuaj ua cov nroj tsuag uas cov kav dej raug corrosive heev acids thiab alkalis, 904L stainless hlau square kav yuav tswj tau lawv cov kev ncaj ncees nyob rau lub sij hawm ntev. Nyob rau hauv ib puag ncig marine, lawv tuaj yeem tiv taus cov teebmeem corrosive ntawm seawater thiab ntsev - laden huab cua, ua rau lawv haum rau siv nyob rau hauv offshore qauv thiab seawater desalination nroj tsuag.

Mechanical Properties

Cov qib stainless hlau no muaj lub zog zoo thiab ductility. Nws tuaj yeem tiv taus nruab nrab mus rau siab siab yam tsis muaj deformation. Lub zog tawm los ntawm 904L stainless hlau feem ntau yog nyob rau hauv ntau yam uas tso cai rau nws los tswj cov quab yuam los ntawm cov khoom ntws los ntawm cov yeeb nkab lossis cov khoom siv sab nraud hauv cov qauv siv. Nws cov ductility ua rau nws tsim rau hauv cov duab square thaum lub sijhawm tsim khoom thiab tseem tso cai rau qee qhov kev khoov lossis shaping thaum lub sijhawm teeb tsa yog tias tsim nyog.

Tsawg kub toughness

904L stainless hlau square kav qhia tau zoo heev toughness txawm nyob rau hauv qis kub. Cov cuab yeej no yog qhov tseem ceeb hauv kev siv xws li kev cia khoom cryogenic thiab kev thauj mus los. Piv txwv li, nyob rau hauv liquefied natural gas (LNG) cov chaw, cov kav dej yuav tsum tau tswj lawv cov neeg kho tshuab kev ncaj ncees thiab tsis kam mus rau nkig tawg ntawm qhov kub tsis tshua muaj qhov xav tau rau LNG cia thiab hloov mus.
