316L Stainless Simbi
Maumbirwo, Hunhu uye Mashandisirwo
Kuti unzwisise 316L simbi isina tsvina, munhu anofanira kutanga anzwisisa 316 simbi isina tsvina.
316 is austenitic chromium-nickel simbi isina tsvina ine pakati pezviviri ne3% molybdenum.Iyo molybdenum yemukati inovandudza corrosion resistance, inowedzera kuramba kugomba mune chloride ion mhinduro, uye inovandudza simba pakupisa kwakanyanya.
Chii chinonzi 316L Stainless Steel?
316L ndiyo yakaderera kabhoni giredhi ye316. Iri giredhi harina kudzivirirwa kubva mukunzwa (grain boundary carbide precipitation).Inogara ichishandiswa mune inorema gauge welded zvikamu (zvinenge kupfuura 6mm).Hapana mutsauko unocherechedzwa wemutengo pakati pe316 ne316L simbi isina tsvina.
316L Stainless simbi inopa yakakwira kukambaira, kushushikana kuputika uye kusimba simba patembiricha yakakwira kupfuura chromium-nickel austenitic stainless steels.
Alloy Designations
Izwi rekuti "L" rinongoreva "kabhoni shoma."316L ine kabhoni shoma pane 316.
Mazita akajairika ndeaya L, F, N, uye H. The austenitic chimiro chemagiredhi aya chinopa kuomarara kwakanakisa, kunyangwe pakupisa kwe cryogenic.
304 vs. 316 Stainless Steel
Kusiyana ne304 simbi - iyo inonyanya kufarirwa simbi isina tsvina - 316 ine yakagadziridzwa yekudzivirira kubva kune chloride nemamwe maasidhi.Izvi zvinoita kuti zvive zvakakosha kune zvekunze zvikumbiro munzvimbo dzemugungwa kana maapplication ane njodzi inogona kuratidzwa kune chloride.
Ose ari maviri 316 uye 316L anoratidza zvirinani kusakara uye simba patembiricha yakakwira kupfuura 304 mumwe wavo - kunyanya kana zvasvika pakukomba uye kukoromoka munzvimbo dzechloride.
316 vs. 316L Stainless Simbi
316 simbi isina tsvina ine yakawanda kabhoni kupfuura 316L.316 simbi isina simbi ine yepakati-renji nhanho yekabhoni uye ine pakati pe2% ne3% molybdenum, iyo inopa kuramba kune ngura, acidic zvinhu, uye tembiricha yakakwira.
Kuti uwane 316L simbi isina tsvina, huwandu hwekabhoni hunofanira kunge huri pasi - kunyanya, haigoni kudarika 0.03%.Iyo yakaderera kabhoni mazinga anoita kuti 316L kuve yakapfava kupfuura 316.
Pasinei nemusiyano wemukati wekabhoni, 316L yakafanana chaizvo ne316 munzira dzese.
Masimbi ese ari maviri asina simbi anoumbika zvakanyanya, anobatsira kana achigadzira zvimiro zvinodiwa kune chero chirongwa pasina kutyora kana kutsemuka, uye ane kukwirira kwekupokana uye kusimba kwakanyanya.
Mutengo pakati pemhando mbiri unofananidzwa.Ose ari maviri anopa kusimba kwakanaka, corrosion-resistant, uye isarudzo dzakanaka mu-high-stress application.
316L inoonekwa seyakanakira purojekiti inoda simbi yakakura.316, kune rumwe rutivi, ishoma-inodzivirira mukati meweld (weld kuora) pane 316L.Izvo zvakati, annealing 316 ibasa rekurwisa weld kuora.
316L yakanaka kune yakakwirira-tembiricha, yakakwira-corrosion kushandiswa, iyo inoratidza mukurumbira wayo mukuvaka uye mapurojekiti emugungwa.
Ose ari maviri 316 uye 316L ane yakanakisa malleability, ichiita zvakanaka mukukotama, kutambanudza, kudhirowa kwakadzika, uye kutenderera.Zvisinei, 316 isimbi yakaoma zvikuru ine simba repamusoro uye ductility kana ichienzaniswa ne316L.

Kuumbwa Kwemakemikari
316l SS kuumbwa inoratidzira yakanyanya kabhoni mazinga e0.030%.Iyo silicon mazinga anokwira pakukwira kwe0.750%.Maximum manganese, phosphorus, nitrogen, uye sulfur mazinga akaiswa pa 2.00%, 0.045%, 0.100% uye 0.030%, maererano.316L inoumbwa nechromium pa16% min uye 18% max.Nickel mazinga akaiswa pa10% min uye 14% max.Iyo molybdenum yemukati ishoma mwero we2.00% uye max ye3.00%.
Mechanical Properties
316L inochengetedza simba shoma re 485 uye simba shoma regoho re120 pa 0.2% uchapupu hwekushungurudzika.Iine kureba kwe40% mu50mm/min uye kuomarara kwakanyanya kwe95kg pasi peiyo Hardness Rockwell B bvunzo.316L simbi isina tsvina inosvika pakuomarara kwe217kg pasi peyedzo yeBrinell scale.
Corrosion Resistance
Giredhi 316L inopa yakanakisa corrosion kuramba munzvimbo dzakasiyana siyana dzinoparadza midhiya uye mamiriro emuchadenga.Iyo inobata zvakanaka kana ichiiswa pasi pekutsemuka uye gomba corrosion mune inodziya chloride mamiriro.Pamusoro pezvo, inoratidza kugara yakasimba kunyangwe iri pasi pekunetsekana kwekupwanya bvunzo kuri pamusoro pe60 ° C.316L inoratidza kuramba kumvura inosvika 1000mg/L chloride mazinga.
316 giredhi Stainless simbi inonyanya kushanda munzvimbo dzine acidic - kunyanya kana ichidzivirira kubva mukuora kunokonzerwa nesarufa, hydrochloric, acetic, formic, uye tartaric acids, pamwe neasidhi sulfates uye alkaline chlorides.
