316L Stainless Hlau Seamless Steel Yeeb Nkab
304 stainless hlau yog cov khoom siv hauv cov hlau tsis muaj steel, nrog qhov ceev ntawm 7.93 g / cm³;nws tseem hu ua 18/8 stainless hlau hauv kev lag luam, uas txhais tau hais tias nws muaj ntau tshaj 18% chromium thiab ntau tshaj 8% npib tsib xee;kub tsis kam ntawm 800 ℃, kev ua haujlwm zoo, siab tawv, dav siv hauv kev lag luam thiab rooj tog kho kom zoo nkauj kev lag luam thiab khoom noj khoom haus thiab kev kho mob kev lag luam.Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias piv nrog 304 stainless hlau zoo tib yam, zaub mov-qib 304 stainless hlau muaj cov ntsiab lus nruj dua.Piv txwv li, cov ntsiab lus thoob ntiaj teb ntawm 304 stainless hlau yog qhov tseem ceeb 18% -20% chromium, 8% -10% npib tsib xee, tab sis cov khoom noj-qib 304 stainless hlau muaj 18% chromium thiab 8% npib tsib xee, tso cai hloov pauv hauv qee qhov ntau, thiab Txwv cov ntsiab lus ntawm ntau yam hnyav hlau.Hauv lwm lo lus, 304 stainless hlau tsis tas yuav tsum yog qib 304 stainless hlau
Stainless hlau seamless kav yog cov kav hlau uas tiv taus qhov tsis muaj zog corrosive media xws li huab cua, chav, thiab dej, thiab tshuaj lom neeg corrosive media xws li acids, alkalis, thiab ntsev.Kuj tseem hu ua stainless acid-resistant steel yeeb nkab.
Kev tiv thaiv corrosion ntawm stainless hlau seamless kav yog nyob ntawm cov alloying ntsiab muaj nyob rau hauv cov hlau.Chromium yog lub hauv paus ntsiab lus rau corrosion kuj ntawm stainless hlau.Thaum cov ntsiab lus chromium hauv cov hlau nce mus txog 12%, cov chromium cuam tshuam nrog cov pa oxygen hauv qhov nruab nrab corrosive los tsim ib zaj duab xis oxide nyias (self-passivation film) ntawm cov hlau., tuaj yeem tiv thaiv corrosion ntxiv ntawm cov hlau matrix.Ntxiv nrog rau chromium, feem ntau siv alloying ntsiab rau stainless hlau seamless kav xws li npib tsib xee, molybdenum, titanium, niobium, tooj liab, nitrogen, thiab lwm yam, kom tau raws li qhov yuav tsum tau ntawm ntau yam kev siv rau cov qauv thiab kev ua tau zoo ntawm stainless hlau.
Stainless hlau seamless yeeb nkab yog lub hollow ntev round steel, dav siv nyob rau hauv roj av, tshuaj, kev kho mob, zaub mov, lub teeb kev lag luam, mechanical instrumentation thiab lwm yam industrial pipelines thiab mechanical structural qhov chaw.Tsis tas li ntawd, thaum lub zog khoov thiab torsion zoo ib yam, qhov hnyav yog sib dua, yog li nws kuj tau siv dav hauv kev tsim cov khoom siv tshuab thiab cov qauv tsim khoom.Nws kuj yog feem ntau siv los tsim ntau yam riam phom, chim, plhaub, thiab lwm yam.
Nws muaj cov txheej txheem tsim khoom hauv qab no:
a.Round steel npaj;b.Cua sov;c.Kub dov piercing;d.Txiav lub taub hau;e.Pickling;f.Sib tsoo;g.Lubrication;h.Txias Rolling processing;i.Degreasing;j.Kev kho cua sov;k.Ncaj nraim;l.Txiav lub raj;m.Pickling;n.Cov khoom kuaj.
