321 belongs rau Asmeskas tus qauv titanium uas muaj austenitic stainless hlau, tus qauv tswj hwm: ASTM A276 / A276M -17
321 stainless hlau muaj cov khoom zoo sib xws rau 304, tab sis vim yog qhov sib ntxiv ntawm titanium hlau, nws muaj kev tiv thaiv zoo rau cov qoob loo ciam teb corrosion thiab lub zog kub. Vim qhov sib ntxiv ntawm titanium hlau, nws tswj tau qhov tsim ntawm chromium carbide.
Cov tshuaj muaj pes tsawg leeg ntawm 321 stainless hlau yog qhia hauv daim duab hauv qab no:
321 Stainless Hlau Daim Ntawv Thov
Kev siv zoo tshaj plaws ntawm 321 stainless hlau suav nrog kev nthuav dav sib koom ua ke, qhov chaw dav hlau, qhov cub tawg, cov khoom siv hluav taws xob, cov ntxaij vab tshaus ua cov ntxaij vab tshaus, tag nrho cov txheej txheem vuam, nrog lossis tsis muaj hlau.
316L belongs rau American standard austenitic stainless hlau, thiab 316L stainless hlau ua raws li tus qauv "ASTM A240/A240M-19"
316L stainless hlau yog ib hom molybdenum uas muaj stainless hlau. Vim muaj molybdenum nyob rau hauv cov hlau, nws tag nrho kev ua tau zoo yog superior rau 310 thiab 304 stainless hlau. Nyob rau hauv qhov kub thiab txias, thaum cov concentration ntawm sulfuric acid qis dua 15 feem pua lossis siab dua 85 feem pua, 316L stainless hlau muaj ntau yam kev siv. 316L 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 feem ntau yog siv rau hauv cov khoom siv pulp thiab ntawv, cov khoom siv hluav taws xob, cov khoom siv dyeing, cov khoom siv ua yeeb yaj kiab, cov kav dej, cov ntaub ntawv siv rau sab nrauv hauv cov tsev nyob hauv ntug dej hiav txwv, nrog rau cov saw saw thiab rooj plaub rau cov watches high-end. Cov khoom siv hauv dej hiav txwv, tshuaj lom neeg, tshuaj pleev ib ce, papermaking, oxalic acid, chiv thiab lwm yam khoom siv ntau lawm; Kev yees duab, khoom noj khoom haus kev lag luam, chaw ntug hiav txwv dej, hlua, CD ncej, bolts, ceev.
Cov tshuaj muaj pes tsawg leeg ntawm 316L stainless hlau yog qhia hauv daim duab hauv qab no:
Qhov tshwm sim:
Kev siv sib txawv ua rau nws nyuaj rau kev sib piv.
321 stainless hlau yog ib qho kev txhim kho ntawm 304 stainless hlau. Qhov sib txawv tseem ceeb ntawm ob yog qhov sib ntxiv ntawm titanium nce carbon tsib zaug. Ntxiv titanium pab tiv thaiv carbide nag lossis daus thaum lub sij hawm vuam thiab thaum kub kub hloov.
Txawm hais tias qhov zoo siab ntxiv ntawm titanium, 321 tseem muaj ntau yam zoo sib xws, ua rau 300 series stainless hlau loj heev. Kev siv ntau yam ntawm 321 stainless hlau yog annealing, hnyav-lub luag hauj lwm lub tsheb tso tshuab, firewalls, stacked linings, aircraft Cheebtsam, thiab lwm yam khoom siv kub.
