316 Thiab 317 Stainless Hlau Hlau
Stainless hlau hlau kos duab (stainless hlau hlau kos duab): txheej txheem hlau yas ua nyob rau hauv uas ib tug hlau pas nrig los yog ib tug hlau dawb paug yog kos los ntawm ib tug tuag qhov ntawm ib tug hlau kos duab tuag nyob rau hauv qhov kev txiav txim ntawm ib tug kos duab quab yuam los tsim ib tug me me-section steel. hlau los yog hlau tsis-ferrous hlau. Cov hlau uas muaj qhov sib txawv ntawm qhov sib txawv thiab qhov ntau thiab tsawg ntawm ntau yam hlau thiab alloys tuaj yeem tsim los ntawm kev kos duab. Cov hlau kos muaj qhov ntev, du nto, cov cuab yeej kos duab yooj yim thiab pwm, thiab kev tsim khoom yooj yim.
Lub xeev kev ntxhov siab ntawm kev kos duab hlau yog peb lub ntsiab lus tseem ceeb ntawm kev ntxhov siab ntawm ob txoj kev compressive kev nyuaj siab thiab ib txoj kev tensile stress. Piv nrog rau lub hauv paus kev ntxhov siab lub xeev qhov twg tag nrho peb cov lus qhia yog compressive kev nyuaj siab, lub kos hlau hlau yog yooj yim mus cuag lub xeev ntawm yas deformation. Lub xeev deformation ntawm kev kos duab yog peb-txoj kev loj deformation xeev ntawm ob-txoj kev compression deformation thiab ib qho tensile deformation. Lub xeev no tsis zoo rau plasticity ntawm cov ntaub ntawv hlau, thiab nws yooj yim dua los tsim thiab nthuav tawm qhov tsis xws luag. Tus nqi ntawm kev deformation nyob rau hauv cov txheej txheem kos duab yog txwv los ntawm nws qhov kev nyab xeeb, thiab qhov tsawg dua qhov deformation, qhov ntau daim duab dhau. Yog li ntawd, ntau qhov kev sib txuas ntawm cov duab nrawm nrawm yog feem ntau siv rau hauv kev tsim cov hlau.
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 molybdenum-muaj stainless hlau. Cov ntsiab lus ntawm molybdenum hauv 317 stainless hlau yog me ntsis siab dua li ntawm 316 stainless hlau. Vim lub molybdenum nyob rau hauv steel, tag nrho cov kev ua tau zoo ntawm cov hlau no zoo dua 310 thiab 304 stainless hlau. Nyob rau hauv qhov kub thiab txias, thaum lub concentration ntawm sulfuric acid qis dua 15% thiab siab dua 85%, 316 Stainless hlau muaj ntau yam kev siv. 316 stainless hlau kuj tseem muaj kev tiv thaiv zoo rau cov tshuaj chloride corrosion, yog li nws feem ntau yog siv nyob rau hauv marine ib puag ncig. 316L stainless hlau muaj cov ntsiab lus siab tshaj plaws ntawm 0.03, uas tuaj yeem siv rau hauv cov ntawv thov uas tsis tuaj yeem nqa tawm tom qab vuam thiab qhov siab tshaj plaws corrosion yuav tsum tau.
