Musiyano uripo pakati peSS304 neSS304L

Kune mazana emagiredhi akasiyana esimbi isina tsvina pamusika.Imwe neimwe yeaya akasiyana magadzirirwo eStainless simbi inopa imwe dhigirii yekurarisa pamusoro uye kupfuura iyo yesimbi isina chinhu.

Kuvepo kweaya masiyaniya esimbi anogona kukonzera kuvhiringika-kunyanya kana mazita & magadzirirwo emasimbi maviri asina tsvina alloys akada kufanana.Izvi ndizvo zvakaita giredhi 304 uye 304L simbi isina tsvina.

Aya maviri maalloys akafanana zvinoshamisa-asi pane musiyano wakakosha.Mugiredhi 304 isina tsvina, iyo yakanyanya kabhoni yemukati inoiswa pa 0.08%, nepo giredhi 304L Stainless simbi ine yakanyanya kabhoni ye0.03%.Iyo "L" mu304L inogona kududzirwa ichireva yakawedzera-yakaderera kabhoni.

Uyu mutsauko we0.05% kabhoni yemukati unoburitsa diki, asi yakamaka, mutsauko mukuita kweaya maviri alloys.

Musiyano weMechanical
Giredhi 304L ine zvishoma, asi zvinocherechedzwa, kudzikiswa kweakakosha makina maitiro ekuita zvichienzaniswa ne "standard" giredhi 304 Stainless simbi alloy.

Semuenzaniso, iyo yekupedzisira tensile simba (UTS) ye304L ingangoita 85 ksi (~ 586 MPa), ishoma pane iyo UTS yegiredhi giredhi 304 isina tsvina, iyo 90 ksi (~ 620 MPa).Musiyano wekusimba kwegoho wakakurisa zvishoma, ne304 SS ine 0.2% yegoho simba re42 ksi (~289 MPa) uye 304L ine 0.2% yegoho simba re35 ksi (~241 MPa).

Izvi zvinoreva kuti kana iwe uine mabhasikiti maviri ematare esimbi uye matengu ese ari maviri ane dhizaini yakafanana, ukobvu hwewaya, uye kuvaka, tswanda yakagadzirwa kubva ku304L yaizove isina kusimba pane yakajairwa 304 basket.

Sei Iwe Uchida Kushandisa 304L, Zvadaro?
Saka, kana 304L isina simba pane yakajairwa 304 simbi isina tsvina, nei munhu angade kuishandisa?

Mhinduro ndeyokuti iyo 304L alloy yakaderera kabhoni yemukati inobatsira kudzikisa/kubvisa kunaya kwecarbide panguva yewelding process.Izvi zvinobvumira 304L Stainless simbi kuti ishandiswe mu "as-welded" state, kunyangwe munzvimbo dzinoparadza zvakanyanya.

Dai waizoshandisa yakajairwa 304 isina tsvina nenzira imwechete, yaizodzikisira nekukurumidza pamajoini e weld.

Chaizvoizvo, kushandisa 304L kunobvisa kudiwa kwekunamisa majoini eweld usati washandisa fomu resimbi rakapedzwa-kuchengetedza nguva nekuedza.

Mukuita, ese 304 uye 304L anogona kushandiswa kune akawanda emamwe maapplication.Misiyano inowanzova midiki zvekuti imwe haitariswe zvakanyanya kubatsira pane imwe.Kana kusimba kwegora kwakasimba kuchidikanwa, mamwe maalloys, akadai segiredhi 316 simbi isina tsvina, anowanzoonekwa seimwe nzira.
