316 Thiab 317 Stainless Hlau Hlau
Kev Taw Qhia Rau Hlau Hlau
Kev kos duab hlau tsis xeb (kev kos duab hlau tsis xeb): ib qho txheej txheem ua cov hlau yas uas cov pas hlau lossis cov hlau dawb paug raug rub tawm ntawm lub qhov tuag ntawm lub pwm kos duab hlau nyob rau hauv qhov kev ua ntawm lub zog kos duab los tsim cov hlau me me lossis cov hlau tsis yog hlau. Cov hlau nrog cov duab sib txawv thiab qhov loj me ntawm ntau yam hlau thiab cov hlau sib xyaw tuaj yeem tsim los ntawm kev kos duab. Cov hlau kos duab muaj qhov loj me meej, nto du, cov khoom siv kos duab yooj yim thiab pwm, thiab kev tsim khoom yooj yim.
Khoom Zaub
Cov yam ntxwv ntawm cov txheej txheem
Lub xeev kev ntxhov siab ntawm kev kos duab hlau yog peb-seem lub xeev kev ntxhov siab tseem ceeb ntawm ob-txoj kev compressive kev ntxhov siab thiab ib-txoj kev tensile kev ntxhov siab. Piv nrog rau lub xeev kev ntxhov siab tseem ceeb qhov twg tag nrho peb qhov kev taw qhia yog compressive kev ntxhov siab, cov hlau kos duab hlau yooj yim dua mus txog lub xeev ntawm yas deformation. Lub xeev deformation ntawm kev kos duab yog peb-txoj kev tseem ceeb deformation xeev ntawm ob-txoj kev compression deformation thiab ib qho tensile deformation. Lub xeev no tsis zoo rau plasticity ntawm cov khoom siv hlau, thiab nws yooj yim dua los tsim thiab nthuav tawm qhov tsis zoo ntawm qhov chaw. Tus nqi ntawm kev hla deformation hauv cov txheej txheem kos duab hlau yog txwv los ntawm nws qhov kev nyab xeeb, thiab qhov me me ntawm kev hla deformation, qhov ntau dua kos duab dhau. Yog li ntawd, ntau zaus dhau ntawm kev kos duab ceev ceev tas mus li feem ntau siv rau hauv kev tsim cov hlau.
Pawg Khoom
Feem ntau, nws muab faib ua 2 series, 3 series, 4 series, 5 series thiab 6 series stainless hlau raws li austenitic, ferritic, ob txoj kev stainless hlau thiab martensitic stainless hlau.
316 thiab 317 stainless hlau (saib hauv qab no rau cov khoom ntawm 317 stainless hlau) yog cov hlau stainless hlau uas muaj molybdenum. Cov ntsiab lus ntawm molybdenum hauv 317 stainless hlau yog me ntsis siab dua li ntawm 316 stainless hlau. Vim yog molybdenum hauv hlau, qhov kev ua tau zoo tag nrho ntawm cov hlau no zoo dua li 310 thiab 304 stainless hlau. Nyob rau hauv qhov kub siab, thaum qhov concentration ntawm sulfuric acid qis dua 15% thiab siab dua 85%, 316 Stainless hlau muaj ntau yam kev siv. 316 stainless hlau kuj muaj kev tiv thaiv zoo rau chloride corrosion, yog li nws feem ntau yog siv rau hauv cov chaw ib puag ncig marine. 316L stainless hlau muaj cov ntsiab lus carbon siab tshaj plaws ntawm 0.03, uas tuaj yeem siv rau hauv cov ntawv thov uas tsis tuaj yeem ua tiav tom qab vuam thiab qhov siab tshaj plaws corrosion tiv thaiv yog xav tau.
