ASTM A182 F53 thiab F55yog cov kev xaiv zoo tshaj plaws duplex stainless hlau, tab sis lawv cov khoom sib txawv thiab cov khoom ua rau lawv haum rau lwm yam kev siv. F53 yog tus nqi ntau dua -zoo, thaum F55 yog qhov zoo tagnrho rau siab - kev ntxhov siab thiab ib puag ncig hnyav.
F53 thiab F55 yog dab tsi?
Super Duplex F53
F53 yog qib duplex stainless hlau nrog lub zog zoo heev thiab kev tiv thaiv corrosion. Cov khoom no ua ke nrog austenite thiab ferrite microstructures, muab kev tiv thaiv zoo tshaj rau pitting, crevice corrosion, thiab kev ntxhov siab corrosion cracking, tshwj xeeb tshaj yog nyob rau hauv chloride - nplua nuj ib puag ncig. F53 qib paub txog nws qhov kev tiv thaiv corrosion siab txawm tias nyob rau hauv cov kua qaub, alkaline, thiab chloride- nplua nuj ib puag ncig. Tsis tas li ntawd, nws kuj muaj cov cuab yeej zoo heev, nrog rau kev ua kom muaj zog tensile, zoo qaug zog tiv thaiv, thiab yoog raws.
Super Duplex F55
Ntawm qhov tod tes,ASTM A182 F55yog qib super duplex stainless hlau uas muaj ntau dua ntawm chromium, molybdenum, thiab nitrogen dua F53. Cov hlau no yog tsim los txhim kho cov tshuaj chloride pitting thiab crevice corrosion kuj thiab muaj corrosion kuj zoo heev nyob rau hauv ntau yam corrosive media xws li acidic, alkaline, thiab chloride daws. F55 tseem paub txog nws cov cuab yeej zoo tshaj plaws, suav nrog lub zog qaug zog thiab zoo heev, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau siab - kev siv kev ntxhov siab.
Qhov txawv Super Duplex F53 Vs F55
Tshuaj muaj pes tsawg leeg
Qhov sib txawv tseem ceeb ntawmF53(S32750, 2507, 1.4410)thiabF55(S32760, 1.4501)yog cov tshuaj muaj pes tsawg leeg.TIAB SA 2507yog stainless hlau uas muaj 14% chromium, 3% molybdenum, thiab 2% npib tsib xee.SWB S32760Ntawm qhov tod tes, yog stainless hlau uas muaj 12% chromium, 4% molybdenum, thiab 3% npib tsib xee.
Tensile zog
Lwm qhov sib txawv ntawm ASTM A182 F53 thiab F55 yog lub zog tensile. Lub zog tensile ntawmASTM A182 F53yog 860 MPa, thaum lub zog tensile ntawm ASME SA182 F55 yog 930 MPa. Qhov no txhais tau tias ASTM A182 F55 muaj lub zog tensile siab dua SA182 F53.
Yield zog
Super duplex F53muaj lub zog tawm los ntawm 550 MPa, thaumSuper duplex F55muaj lub zog tawm los ntawm 690 MPa. Qhov no txhais tau tias F55 muaj lub zog tawm los ntau dua F53.
Elongation ntawm Break
Lub elongation ntawm qhov tawg ntawm F53 cov khoom yog 30%, thaum qhov txuas ntxiv ntawm qhov tawg ntawm F55 cov khoom yog 35%. Qhov no txhais tau hais tias ASTM A182 F55 muaj qhov elongation siab dua thaum tawg dua ASTM A182 F53.
Nqi
Thaum muab piv rau ob qib ntawm ASTM A182, F53 muaj tus nqi qis dua F55 vim nws cov ntsiab lus chromium thiab molybdenum qis dua. F53 kuj tseem muaj lub zog qis dua thiab tiv thaiv corrosion hauv acidic thiab chloride- nplua nuj ib puag ncig tshaj F55. Ntawm qhov tod tes, F55 muaj kev tiv thaiv ntau dua rau pitting, crevice corrosion, thiab kev ntxhov siab corrosion tawg, uas ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv qhov chaw corrosive heev.
Daim ntawv thov
F53 thiab F55 qib ntawm ASTM A182 muaj ntau yam kev siv hauv kev lag luam sib txawv. F53 feem ntau yog siv rau hauv kev ua tshuaj lom neeg, kev lag luam roj thiab roj, thiab kev siv dej hiav txwv uas muaj corrosive ib puag ncig. Nyob rau tib lub sijhawm, F55 yog qhov zoo tagnrho rau kev ua haujlwm siab - kev ua haujlwm xws li kev ua haujlwm sab nrauv thiab kev tsim nkoj, kev ua tshuaj lom neeg, thiab tsim hluav taws xob.
