1. Hordhac kooban oo saxan bir ah oo S355J0W ah:
S355J0W waa bir u adkaysata jawiga jawiga Yurub, taas oo iska leh saxan bir ah oo cimilada u adkaysata.Waa bir-daawaha hoose oo lagu sameeyay iyadoo lagu darayo xaddi gaar ah oo walxaha alloy ah birta caadiga ah.Iska caabinta daxalka atmospheric birta cimiladu waa 2-8 jeer ka birta kaarboonka caadiga ah, waxayna leedahay sifooyin farsamo oo wanaagsan, sifooyin alxanka, iwm.
2. S355J0W waxay hagaajisay birta u adkaysata daxalka atmospheric
Qadar gaar ah oo walxo isku dhafan ayaa lagu daraa birta, sida P, Cu, Cr, Ni, Mo, si loo kordhiyo iska caabinta daxalka hawada, iyo saameynta xaaladaha cimilada, oksaydh ilaalin toos ah ayaa dib loo soo celin doonaa biraha salka.
3. Heerka gaarsiinta S355J0W:
Lagu keenay qaab duuban oo kulul, caadiyan ama xaalad duuban oo caadi ah.
Afar, S355J0W saxan bir ah heerka fulinta:
S355J0W waxay fulisaa EN10025-5: 2004 heerka.
5. S355J0W waxay hagaajisay birta u adkaysata daxalka atmospheric
Qadar gaar ah oo walxo isku dhafan ayaa lagu daraa birta, sida P, Cu, Cr, Ni, Mo, si loo kordhiyo iska caabinta daxalka hawada, iyo saameynta xaaladaha cimilada, oksaydh ilaalin toos ah ayaa dib loo soo celin doonaa biraha salka.
6. Awoodeena sahayda:
1. Qiyaasta saxanka birta ee la heli karo: dhumucdiisuna tahay 8-700mm, ballac 1500-4020mm, dhererka 4000mm-17000mm, miisaanka cutubka ilaa 30.00 tan.Taarikada birta cabbirka ka weyn ayaa sidoo kale la heli karaa marka la codsado.
2. Noocyada taarikada birta ah ee la heli karo: taarikada dhismaha kaarboonka, birta birta ah ee hooseeya ee hooseeya, birta birta ah ee buundooyinka, taarikada birta ee dhismayaasha dhismaha, taarikada birta ee dhismaha maraakiibta iyo maraakiibta xeebaha, taarikada birta ee kululeeyaha iyo weelasha cadaadiska, birta Taarikada loogu talagalay caaryada, taarikada birta ee dhismayaasha alloy, Waxaa jira 12 qaybood oo taarikada birta ah oo loogu talagalay dhuumaha saliidda iyo gaasta, taarikada birta ee xoogga badan iyo adagaanta, taarikada birta u adkaysata, iyo taarikada birta isku dhafan, oo leh in ka badan 300 gudaha iyo calaamado shisheeye.
3. Loo heli karo shuruudaha ogaanshaha cilladaha, Z15-Z35 dhumucda shuruudaha waxqabadka jihada, xoogga sare iyo shuruudaha adag ee sare iyo taarikada kale ee birta.
4. Waxaa la keeni karaa iyadoo loo eegayo heerarka qaranka, heerarka biraha, heerarka American AISI / ASME / ASTM, Japanese JIS, Jarmal heerka DIN, French NF, British BS, European EN, caalamiga ah ISO iyo heerarka kale.
