Iwe unoona 316 uye 316L Stainless simbi inotsanangurwa nguva dzese, asi mutsauko chaiwo hausi vara riri padhetabheti. Zviri mumaweld, makomba ekuora, nenhengo dzinodzoka kubva kumunda. Vazhinji vanofunga kuti vanochinjana. Havasi, uye ndaona fungidziro inodhura.
Iyo Carbon Zvirimo: Haisi Ingori Nhamba
Musiyano mukuru icarbon. 316 ine huwandu hwe0.08%, nepo 316L simbi isina tsvina wakashanduka kusvika muna +0.03%. Zvinonzwika zvisina basa, handiti? Muchirevo, zvichida. Asi mukuita, iyo kabhoni inoda kusanganisa nechromium panguva yewelding, ichigadzira chromium carbides pamiganhu yezviyo. Uku kunzwisiswa kunoba chromium inopa simbi kuramba kwayo kuita ngura, ichisiya nzira isina njodzi padivi penzvimbo yeweld yakakanganiswa nekupisa. Kune chikamu chinongogara ipapo, pamwe zvakanaka. Kune chero chinhu chakatarisana nema chlorides kana acids, inzvimbo yakafanomisikidzwa yekutadza.
Ndinorangarira bhechi remiviri yevharuvhu yemutengi wekugadzira makemikari. Iyo yakadhindwa yakangoti 316 isina tsvina. Iyo shopu, ichiedza kuchengetedza mashoma mari pakirogiramu, yakashandisa yakajairwa 316 bar stock. Mativi acho akanga akagadzirwa zvakaisvonaka, akapfuura nzvero yokutanga. Asi mwedzi mitanhatu gare gare, takawana mifananidzo: yakanaka, dandemutande-kunge makatsemuka kubva pamusono wega wega. Intergranular corrosion. Mutengi wacho, zvinonzwisisika, akashatirwa. Ndopaunodzidza kubvunza, pakarepo: Izvi zvichave zvakasungwa here? Ndeipi nzvimbo yebasa? Kana mhinduro iri hongu kune welding, unosundira iyo L giredhi. Hapana nharo.
Ichi ndicho chikonzero chekutsvagisa kwezvinhu zvemupi kuchikosha. Kambani yakadai QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. (QSY), nemakumi matatu emakore ekukanda uye machining, vaizowana izvi. Paunenge uchiita Investment casting kana CNC machining zvikamu zvichave chikamu chegungano rakakura rakashongedzwa, kutanga negiredhi yakaderera-kabhoni haisi sarudzo-ndiyo chete sarudzo ine njere. Chiitiko chavo nemaaloyi akakosha zvinogona kureva kuti vaona mhedzisiro yekukanganisa kwezvinhu.
Machinability uye Formability: The Shop Floor Reality
Ngatitaurei nezvekucheka nekuumba. Kunyange 316 kana 316L chiroto chemuchina - ivo vane gummy, vanoshanda-kuoma sekupenga kana ukasangwarira. Asi pakati pezviviri izvi, ini ndaipa mupendero mudiki kune 316L yekudzikamisa machining muzvikamu zvakaoma. Iyo yakaderera kabhoni inoita kunge inokonzeresa kushomeka kunoenderana chip break, kushoma maitiro ekuvaka-kumusoro mupendero pachishandiso, kunyanya mukuenderera mberi kwekuita sekushandura maprofiles epombi impellers.
Pakuumba kana kuumba, 316L inowanzo regerera. Kusimba kwayo kwegoho rezasi uye nepamusoro ductility pakutanga kunoita kuti zvive nyore kusundira mune yakaoma kunzwisisa shell mold casting mapatani pasina nyaya dzekare. Isu takambofanira kudzika-kudhirowa mamwe makapu akatetepa-akakomberedzwa kubva ku316 sheet. Yekutanga kumhanya neyakajairwa 316 yakakonzera 30% chirahwe mwero kubva kudiki-diki paradius yakadhonzwa. Yakachinjira ku316L, uye nyaya yacho yakanyangarika. Nyaya yacho yaingoyerera zviri nani.
Ichi chinhu chakakosha kune vanogadzira. Kana iwe uchitsvaga mapre-formed castings kana ma blanks emuchina, kutsanangura giredhi chairo rekugadzira hafu yehondo. Mudiwa anonzwisisa maitiro, senge zvaungawana tsngtaocnc.com, hakusi kungokutengesa simbi here; vari kushandisa yavo CNC machining uye kukanda ruzivo rwekusarudza giredhi rinozoita senge pasi pematurusi avo uye molds, kuchengetedza munhu wese misoro pasi pemutsara.
Iyo Corrosion Ngano uye Molybdenum Chokwadi
Imwe ngano yakajairika ndeyekuti 316L inonyanya kushingirira pane 316. Kwete chaizvo. Kuramba kwavo kwekutanga, kwakapihwa neiyo 2-3% molybdenum uye chromium-nickel matrix, yakafanana mune yakavharwa, isina-weld state. Iyo molybdenum ndiyo kiyi-ndiyo inopusha kuramba kwegomba uye kukoromoka kwegora munzvimbo dzechloride dzinopfuura 304. Kubatsira kwegiredhi reL ndiko chete kuchengetedza kupikisa kwemukati mushure mekutenderera kwekupisa senge welding.
Asi heino nuance: mune yakanyanya oxidizing asidhi (senge nitric), iyo nyaya inogona kupinduka. Pane imwe data uye anecdotal humbowo kubva mumaoko ekare ayo akajairwa 316 anogona dzimwe nguva kuita zvirinani mune idzi dzakananga, dzisiri-chloride nharaunda. Chimwe chinhu pamusoro pekugadzikana kwefirimu. Ini handina kubheja chirongwa pairi, asi chiyeuchidzo chekuti sainzi yenyama haiwanzo mhedziso. Iwe unofanirwa kuziva muvengi chaiwo chikamu chakatarisana nacho.
Kune yakajairwa marine, makemikari, kana chikafu chekugadzira zvikumbiro-apo ma chlorides, organic acids, kana sterilizing solutions aripo-kukosha kwe welded 316L simbi isina tsvina inoita iyo default. Ndiyo yakachengeteka, inogoneka sarudzo yemidziyo yakagadzirwa. Kana ini ndichitarisa iyo portfolio yenyanzvi yakaita seQSY, iyo inosanganisira masimbi aya uye nickel-based alloys kune kunyangwe akaomesesa mabasa, zvinoratidza kuti vajaira kubata neaya nuanced, anotyairwa-anotungamirwa nekushandisa, kwete kungofambisa generic simbi stock.
Mutengo uye Sourcing: Iyo Inoshanda Calculus
Ehe, 316L kazhinji inotakura premium diki. Asi kuongororwa kwemitengo hakuna musoro kana yakamira painvoice yeraw material. Iwe unofanirwa kuisa mumutengo wakazara wekugadzira uye lifecycle. Kana ukashandisa mwero 316 zvichireva kuti unofanira kuvharisa mawelds kunyungudutsa macarbides (imwe nhanho, inodhura, uye inowanzokanganisa), kana kuti ukatadza kukundikana, masvomhu anoshanduka ipapo ipapo. Iyo L giredhi inowanzobvisa iyo post-weld kupisa kurapwa inoda.
Kutsvaga chimwe chinhu. Nekusundirwa kwepasi rose kwemaitiro, weldable structural stainless, 316L inowanzowanikwa nyore nyore mumhando yakawanda yemhando-ndiro, pombi, fittings, castings-kupfuura chiyero 316. Kuedza kutsvaga saizi chaiyo muchokwadi 316 bar stock yebasa rekugadzira dzimwe nguva inogona kutora mavhiki kureba kupfuura kuwana 316L mumwe wayo.
Kuwanikwa uku kunodyisa mumaketani ekupa akavimbika kune vanogadzira. Kushanda kwenguva refu, seQingdao Qiangsenyuan Technology Co., Ltd., iyo inosimbisa zvinhu zvakaita se. simbi isina tsvina uye alloys akakosha, anogona kunge akagadzira nzira dzemagiredhi akakodzera. Nhoroondo yavo yemakore makumi matatu inoratidza kuti vakavaka hukama kuti vawane kwete simbi chete, asi simbi chaiyo yebasa racho, rinowanzova basa rakaoma.
Mutongo Wechishandiso: Nguva Yokushandisa Ipi
Saka, mutemo wakapfava wegunwe: kana ichave yakashongedzwa uye yakatarisana nebasa rinoparadza, shandisa 316L simbi isina tsvina. Full stop. Izvi zvinovhara 90% yemaindasitiri ekushandisa-mapombi masisitimu, midziyo yekumanikidza, muchina wekugadzira chikafu, zvemugungwa, matangi emishonga. Kuvimba kwakawedzerwa kunokodzera musiyano wemutengo muduku.
Ndepapi paungafunga nezve standard 316? Kune zvisina-welded components, kana maapplications uko kusimba kwepamusoro-tembiricha (pamusoro pe800°F) ndiyo inonyanya kunetsa, sezvo iyo kabhoni yakakwira zvishoma inogona kupa simba rekukambaira riri nani. Funga nezvezvimwe zvikamu zvechoto, mashafu asina-welded, kana zvimwe zvekusungirira. Asi kunyangwe zvakadaro, uri kutengesa mukana wepamusoro-tembiricha bhenefiti yeyakavimbiswa weldability chirango. Iyo niche sarudzo.
Pakupedzisira, zvinouya pasi kune ruzivo ruzivo. Hazvirevi kuti giredhi rimwechete riri nani, asi kuti rimwe rinenge rakakodzera. Chinangwa ndechekufananidza zvivakwa zvemukati nemaitiro ekugadzira uye kupedzisira-kushandiswa kushungurudzwa. Ndirwo rudzi rwekutonga kunoshanda kunopatsanura mupi wezvikamu kubva kune wechokwadi kugadzira mudiwa. Ndiwo mutsauko pakati pekungoita chimiro uye kuendesa chikamu chinoita, uye chinogara, munyika chaiyo.
