Cov hlau tsis xeb 316 thiab cov hlau tsis xeb 316L yog ob qho tib si austenitic, nrog rau cov qib zoo sib xws ntawm chromium (16–18%), nickel (10–14%), thiab molybdenum siab (2–3%). Qhov sib txawv tseem ceeb yog 316L cov ntsiab lus carbon qis dua 0.03%, piv rau 0.08% siab tshaj plaws rau 316. Cov pa roj carbon qis dua txo qhov kev sib tsoo ntawm chromium carbide thaum lub sijhawm vuam.
316 piv rau 316L
*
Chromium carbide precipitates ntawm cov ciam teb thaum muaj qhov kub siab, tshwj xeeb tshaj yog ntawm 450 ° C thiab 850 ° C, zoo li nyob rau hauv thaj chaw uas raug cua sov vuam. Qhov "sensitization" no ua rau chromium ploj mus hauv zos thiab ua rau muaj kev cuam tshuam rau kev xeb intergranular, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj chloride hnyav.
Kev Ua Tau Zoo, Kev Tiv Thaiv Kev Xeb, thiab Kev Sib Txuas Lus
Cov Yam Tseem Ceeb ntawm Kev Tiv Thaiv Kev Xeb
316 stainless hlau thiab 316L stainless hlau ua rau muaj kev tiv taus huab cua thiab tshuaj lom neeg corrosion vim lawv cov ntsiab lus molybdenum 2-3%. Qhov sib txawv ntawm 316 thiab 316L stainless hlau yog nyob rau hauv lawv cov kev ua tau zoo tom qab-fabrication: 316L cov ntsiab lus carbon yog ≤0.03%, piv rau ≤0.08% rau 316, txo qis carbide precipitation ntawm cov ciam teb noob tom qab welding. Cov cuab yeej no ua rau 316L stainless hlau zoo tshaj plaws rau cov chaw uas muaj kev cuam tshuam rau chlorides thiab acids, xws li cov khoom siv marine, cov kav dej ua haujlwm, thiab cov tank tshuaj lom neeg, tswj cov qhov thiab crevice corrosion tsis kam, txawm tias ntawm thaj chaw weld.
Kev Xav Txog Kev Sib Txuas Lus
316L stainless hlau muab kev sib txuas zoo dua rau cov qauv vuam hauv kev tsim kho, kev kho mob, thiab kev lag luam tshuaj lom neeg. Nws cov pa roj carbon tsawg (u003c0.03%) tiv thaiv kev tsim chromium carbide thaum raug cua sov, tiv thaiv kev xeb intergranular thiab poob ntawm kev tiv thaiv xeb ntawm cov pob qij txha. Qhov cwj pwm no zam kev vuam tsis muaj zog, tsim xeb, thiab kev saib xyuas kim, uas yog kev pheej hmoo thaum 316 stainless hlau siv tsis raug hauv cov ntawv thov nrog qhov ceev vuam siab lossis rov ua dua thermal cycling. Piv txwv li, cov khoom siv kho mob cog, cov hlab ntsha siab, thiab cov khoom siv ua zaub mov siv 316L xwb kom tsis txhob muaj kev puas tsuaj ntawm thaj chaw vuam.
