AISI 904L Stainless hlau Properties
1.4539 Ibyog ib qib ntawm super austenitic steel, ib feem cais raws li npib tsib xee alloys. Muab nyob rau hauv daim ntawv ntawm cov khoom ntev thiab tiaj tus, nws yog siv tsuas yog nyob rau hauv cov tshuaj, lub zog thiab petrochemical industries, qhia tsis kam mus rau ntau yam concentrations ntawm kub sulfuric acid, phosphoric acid, nitric acid thiab orthophosphoric acid.
luj 904lthiab nws cov kev hloov pauv yog nyob rau hauv cov pab pawg ntawm steels resistant rau intercrystalline corrosion nyob rau hauv tus me nyuam thiab sensitized mob, uas mus tes nyob rau hauv tes nrog tsis kam mus pitting thiab kev nyuaj siab corrosion. Tsis tas li ntawd, nws yog tus cwj pwm los ntawm kev nce slit thiab pitting corrosion kuj, thiab zoo weldability. raws li TMT, lub supersaturation yog nqa tawm ntawm qhov kub thiab txias ntawm 1050 - 1150℃thiab forging thiab dov ntawm 900 - 1200℃.
Cov txiaj ntsig ua haujlwm tseem ceeb
Sulfuric Acid Resistance:Kev suav nrog tooj liab ua rau 1.4539 muaj zog tiv thaiv ntau yam ntawm sulfuric, phosphoric, thiab acetic acids ntawm qhov kub siab.
Weldability zoo heev:Nws qhov qis - carbon specification txo qis carbide nag lossis daus thaum vuam, khaws cia intergranular corrosion kuj nyob rau hauv tshav kub- cuam tshuam cheeb tsam (HAZ).
High Pitting Resistance Equivalent Number (PREN):Muab kev txhim khu kev qha nyob rau hauv dej hiav txwv thiab aggressive marine ib puag ncig piv rau tus qauv 316L stainless hlau.
Common Industrial Use Cases
Chemical Processing & Petrochemicals:Cov Scrubbers, heat exchangers, thiab piping networks tuav qaub oilfield kua los yog volatile acids.
Pulp thiab Ntawv Kev Lag Luam:Cov khoom siv tshuaj ntxuav tes thiab cov hlab ntsha siab.
