AISI 304: iimpawu zobugcisa. steel stainless

AISI 304 iinkcukacha onokuyi fumana kweli nqaku, imbono yokuba iintlobo eziphambili yentsapho yodidi stainless. Le nto - steel austenitic enesiqulatho onekhaboni ephantsi ngokufanelekileyo. Ekubeni ngomsebenzi nemigangatho karhulumente, asetyenziswa eRashiya, uyakwazi ukuqonda ukuba umfuziselo lokuyibabala kwibanga steel 08H18N10.

izinto ezichazwe asidi-enganyangekiyo, ukongeza, ukuba abe nako ukunyamezela exposure elifutshane elide lobushushu ukuya ku-900 ^o C. Kodwa ezi mpawu ezikhethekileyo asingabo kuphela ezo kufuneka zihlawulwe, abaninzi kubo, ukuba babe ngqo, esisigxina, kwaye kuya kuxoxwa ngezantsi.

iimpawu technical

AISI 304 iinkcukacha ekufuneka zifundwe ngaphambi nokufunyanwa, onokuxinana kwi uluhlu 7.9 ukuya 7,93 g / cm ^3. uqine ngu 505 MPA, lo gama uxinzelelo hoxa ngu 215 MPA. Vickers yobulukhuni ngu 129, Knoop yokuqaqadeka ngu 138. Ukuba umsebenzisi abucala, kufuneka sinikele ingqalelo ekulandeleni le GOST impahla.

AISI 304 iinkcukacha ekufuneka kukunceda wenze ukhetho olufanelekileyo, kukho plasticity kwinqanaba-70%. Oku kuyinyaniso ukuba Ebubanzini plate-50 mm. Le modulus of okubuyela kwimo yesixhobo isusela ukusuka 193 ukuya 200 uTsvangirai. Le modulus uchebe ngu 86 uTsvangirai. Bushushu, lo permeability ngemagnethi ngu 1.008. ukumelana lombane kumda 7.2e-005 Ohm-cm, okuyinene ukuba amaqondo obushushu 20 ° ^C Esi sicwangciso yatshintshwa kwi 1.16E-04, ukuba ubushushu 650 ° ^C.

abasebenzisi abaninzi ubushushu banomdla Okuninzi oluthile, kulo mzekelo, kwaba 0.5 kJ / (g · K). Mhlawumbi ungathanda kakhulu lobushushu yokunyibilika a, ikwatshintsha kuluhlu ukususela 1400 ukuya 1455 ^C. I conductivity thermal zokufunda 16.2 W / (m · K).

Isicelo olusisiseko kunye neempawu ezithile

AISI 304, iimpawu ezo thaca ngentla zisetyenziswa ukuvelisa umoya kwaye nomsi, ngokunjalo umsi. izinto Excellent kwaba ekwenziweni izixhobo ukugcinwa, imveliso kunye nokuthuthwa newayini, ibhiya, ubisi kunye nezinye iziselo kunye neekhemikhali. Steel isetyenziswa ekwenziweni izixhobo ukutya kunye imichiza mveliso, kwakunye ezabelwe ukutya.

Nalo wenza amagumbi okudlela kunye nekhitshi, kwakunye nemibhobho kwiinjongo ezahlukeneyo. Okuninzi oba zentsimbi kunye iziqalelo isiseko lwemithombo. Sheet AISI 304 - material emele kwibakala esisiseko yentsapho yodidi stainless. izithako ezongezelelekileyo eziqulethwe Kr, ogama ukwakheka kufuneka abe yi-18%. Malunga Ni, ubunzima bayo umthamo yi-10%. Loo umxholo wokuqala uthe izithako ebangela ukuyilwa phezu komhlaba umaleko oxide, oko kunika izinto amelane imichiza ezahlukeneyo. Olu lulwahlulo izinto kwi ekwakhiweni kwenza kube lula ukusebenzisa antiferromagnetically propati.

Ulwazi malunga nokuqulunqwa kwenqaku

AISI 304 stainless sheet sentsimbi uhlanganisa, njengoko sele kuchaziwe ngentla esuka Kr, nto leyo iqulethwe ekwakhiweni ekungabonini ukusuka-18 ukuya kuma-20%. Ngokuphathelele C, ngoko nokuqulethileyo eliphezulu ngu 0.08%. Fe ukuze eziqulathwe kule nkcazelo mali ka-66,345 ukuya 74%, ngembeko MN, ngoko waqamba wayo ungadluli kwi-2%. Ni kwi sheet iqulathe ukususela-8 ukuya 10.5%, ngokubhekisele P kunye S, koko kuxutyushwe zabo eliphezulu 0,045-0,03%, ngokulandelelana.

inkcazelo steel

Kuchazwe kwinqaku uphawu wafumana ukusasazeka kwayo ekwenziweni metal welding, kwaye olwalusele, izixhobo zokusebenza ekhaya kunye namacandelo nezilinganisi umbhobho. Ukuba uhlobo ikhankanya yilinen, ngentsimbi nga zihlelwe kwisimo eshushu-liqengqiwe nengqele-ezityikitywe, njengoko kumiselwe yi ubugcisa bemveliso. metal Flat yaqaphela ngokohlobo imiqulu sheets. Umphezulu we web kwinkqubo zemveliso ziphathwe ngendlela ethile ngenxa zingafumaneka alandelayo iinguqulelo bomhlaba:

• esipilini;
• luze;
• Mat.

On sale kwenzeka umbhobho engatyiwa, nto leyo yenziweyo zombane-ndlela. Le nto ke phantsi umhlwa kwezo ndawo apho umonakalo okanye imikrwelo kwakhiwa. Imigqomo eyenziwe kulo zentsimbi ingasetyenziswa ngokwabo iindleko zothutho kunye nokugcinwa imveliso lweshishini lemichiza, yokudla. Kwimeko yokuqala sithetha imichiza buthathaka.

Le steel ityhubhu ezimile unokuba ebuxande, isetyhula okanye isikwere cross-candelo. Xa indlela yokuvelisa ezi mveliso ungabinazingxaki okanye electrofusion. Umphezulu kwezi zifo likhazimliswe, aqatywe okanye esipilini. AISI 304 (GOST 08H18N10) isetyenziselwa nokuveliswa casks uboya, kvass kunye utywala, kwakunye nezixhobo zemveliso, jiko, imigqomo, izixhobo zobisi, neempahla cryogenic, evaporators, neengcedevu okupholisa.

Iimpawu umbhobho steel AISI 304

Ukususela izinto echazwe nqaku wavelisa tube engatyiwa, leyo iinkcukacha efanayo naleyo echazwe apha ngasentla. Ezi mveliso asetyenziswa ngokubekwa imibhobho kuba lonxibelelwano kule meko babe ngobuqhophololo ngokupheleleyo, nokumelana, musa ukungena ekudibaneni kwemichiza kunye nezinye izinto kwaye abe nesakhono ukuzinyanga xa zonakele.

Ezi imibhobho ukuba akukho deformations kunye izitenxo, babe ukutyabeka of chromium oxide, enika uxhathiso bume lwangaphandle. Iimveliso namandla elungileyo, ukuba encedisa ngokugqibeleleyo nge welding, kufuneka iqondo eliphezulu bhetyebhetye kunye ukuxhathisa lobushushu. Zonke iimpawu ezingundoqo zigcinwa naxa iimeko kumaqondo obushushu asezantsi kakhulu. Ezi mveliso luphawulwa obude-ubomi, lula ufakelo lula ufakelo.

Scope Umbhobho stainless

pipe steel stainless bafumana ukusasazeka kwayo phantse kuyo yonke indawo. Ine- imbonakalo nomtsalane, nto leyo eyenza ingqokelela na bume. pipe steel stainless zingasetyenziswa ukwenza iingcingo, izinyeliso kunye ngezinyuko, nge welding, kunye nentsimbi olwalusele, apha ziquka uxande okanye neetyhubhu isikwere, kunye neemveliso profiled. imibhobho ezinjalo zisetyenziselwa ukwakha zaba kwiindawo ezibalulekileyo, babe yinxalenye yenkqubo zeemoto isithuthi sakho, kwaye asetyenziswe ekwenziweni macandelo zeemoto kunye iiglasi zazo.

Inkcazelo Stainless Ingqiniba

Ingqiniba AISI 304 nayo ingafunyanwa kwi kwimarike namhlanje. Banako ukuba zonke iintlobo imiphezulu, ethe zikhankanywe apha ngasentla brashtovannaya komhlaba isetyenziswa njengento lwalo olongezelelweyo. Kwiimpompo inokuba eqhelekileyo, okanye evuthelweyo. Lo msebenzi wenziwa ngendlela eqhelekileyo yaye radius umtya kwi uluhlu 1.5 ubukhulu sicatshulwa. Ebubanzini bodonga zingaqala mm 1 ukuya 9 ngoxa ubukhulu lilingana isafobe mm 12 ukuya 406.

Inkcazelo Stainless Wire

AISI Wire 304 senziwe ngokuhambelana nemigangatho yezizwe ngezizwe, i-uluhlu ubungakanani ziyahluka ukusuka mm 1.5 ukuya kwi-10. Unakho ukuthenga izinto eziphathekayo yokuqaqadeka ezahlukeneyo, xa kufikwa iintlobo okuthambileyo, kule meko kuba 500 N / mm². Ukuba oyifunayo, ucingo zingathengwa spring ukuqina kulo mzekelo iya yayiphawuleka manqanaba alandelayo kule parameter: 1400 N / mm².

Le ngonyango nala matte okanye esipilini. Wire esetyenziswa kwishishini ukutya, ulwakhiwo, iikhemikhali kunye zoxubo mveliso. Ingasetyenziswa ekwenziweni yokwakha izakhiwo, electrode, imithombo, izacholo zokubhala.

isiphelo

steel stainless ifumene ukusasazwa kwayo ngokubanzi, oko zifunwa phakathi kwabathengi zesiqhelo kunye neengcali, ngokuba le nto yonke. It has ebalaseleyo yokusebenza nokumelana kunye namachibi. Zibonisa weldability egqwesileyo kwaye iimpawu ezibalaseleyo lobushushu eliphantsi.
