Stainless hlau 321 yeeb nkab khoovbelongs rau cov yeeb nkab haum uas tsim los hloov cov kev taw qhia ntawm cov kua los yog roj ntws hauv cov kav dej. Nws yog tsim los ntawm 321 stainless hlau, titanium-stabilized austenitic alloy, thiab muaj nyob rau hauv cov ces kaum (45 degree, 90 degree, 180 degree) thiab kev cai kaum raws li kev xav tau ntawm kev lag luam.
Hais txog peb
HT PIPE yog ib tug thawj coj stockist thiab thoob ntiaj teb exporter nrog ntau tshaj 15 xyoo ntawm kev txawj ntse nyob rau hauv thoob ntiaj teb kev lag luam. Peb muab cov kav dej, daim hlau, cov kab tuav, thiab ntau yam ntawm cov yeeb nkab fittings, flanges, thiab li qub. Tiv tauj peb tam sim no rau cov lus qhia pub dawb thiab cov ntaub ntawv khoom ntiag tug.
Cov yam ntxwv tseem ceeb
Temperature resistance range:Lub sij hawm ntev siv kub -196℃~ 650 degree, luv luv tuaj yeem tiv taus kub ntawm 800 degree.
Corrosion kuj:Nws muaj kev tiv thaiv corrosion zoo dua li 304 stainless hlau hauv nruab nrab thiab tsis muaj zog acidic media (xws li dej tshiab, chav dej, thiab cov kua tshuaj me me), tshwj xeeb tshaj yog nyob rau hauv kub oxidation thiab intergranular corrosion kuj.
Mechanical zog:Lub zog tensile Ntau dua lossis sib npaug ntawm 515MPa, lub zog tawm los Ntau dua lossis sib npaug ntawm 205MPa, elongation Ntau dua lossis sib npaug li 40%, nrog kev khoov zoo thiab weldability.
