ASTM A312 TP321 Stainless hlau Seamless Annealed Tube
ASTM A312 TP321 yog titanium -stabilized austenitic stainless hlau seamless raj, renowned rau nws zoo heev siab - kub lub zog, corrosion kuj (tshwj xeeb tshaj yog tsis kam mus rau intergranular corrosion), thiab weldability. Piv rau welded raj, nws cov qauv seamless muab lub zog ntau dua, thiab cov txheej txheem annealing tshem tawm kev ntxhov siab thiab txhim kho ductility. Nws yog feem ntau siv nyob rau hauv dav hlau tso tshuab, cua sov exchangers, thiab cov khoom siv tshuaj.
A312 TP321 khoom yog dab tsi?
ASTM A312 TP321H yog siab -carbon titanium-stabilized austenitic stainless hlau. Nws cov ntsiab lus muaj xws li 18% chromium thiab 8% npib tsib xee, yog li nws tseem hu ua 18/8 steel.
ASTM A312 TP321 stainless hlau seamless yeeb nkab yog lub siab -kev ua tau zoo, ntau- lub hom phiaj stainless hlau yeeb nkab dav siv hauv ntau yam kev lag luam. Cov yeeb nkab no los ntawm ntau yam kev qhia tshwj xeeb, nrog rau sab nraud feem ntau yog li ntawm 6 hli mus rau ntau pua mm, thiab ntau yam ntawm phab ntsa thicknesses. Nws cov khoom ua raws li tus qauv ASTM A312, kom ntseeg tau tias cov khoom zoo thiab kev ua tau zoo raws li cov qauv thoob ntiaj teb.
ASTM A312 TP321 stainless hlau seamless yeeb nkab feem ntau yog tsim los ntawm chromium (Cr), npib tsib xee (Ni), thiab ib qho me me ntawm titanium (Ti).
Qhov sib ntxiv ntawm cov ntsiab lus no muab cov yeeb nkab tshwj xeeb cov khoom:
Chromium (Cr): Txhim kho cov khoom siv tiv thaiv corrosion, zoo tiv thaiv yaig los ntawm ntau yam xov xwm corrosive.
Nickel (Ni): Txhim kho cov khoom toughness thiab siab -kub oxidation kuj.
Titanium (Ti): Raws li cov khoom ruaj khov, nws muaj txiaj ntsig zoo tiv thaiv nag lossis daus ntawm chromium carbide thaum lub sijhawm vuam, yog li tsis txhob cuam tshuam cov teeb meem cuam tshuam hauv cov vuam thiab cua sov- thaj tsam cuam tshuam, ua kom muaj kev ruaj ntseg ntawm cov yeeb nkab.
