ST37 gariiradda birta kaarboon
Sharaxaada Alaabta
ST37 steel (1.0330 walxo) waa qabow sameeyay heerka Yurub qabow saxan bir kaarboon-yar oo tayo sare leh. Heerarka BS iyo DIN EN 10130, waxaa ku jira shan nooc oo bir ah: DC03 (1.0347), DC04 (1.0338), DC05 (1.0312), DC06 (1.0873) iyo DC07 (1.0898). Tayada dusha sare waxa loo qaybiyaa laba nooc: DC01-A iyo DC01-B.
DC01-A: Cilladaha aan saameynaynin qaabaynta ama dahaarka dusha sare waa la oggol yahay, sida godadka hawada, godadka yar yar, calamadaha yaryar, xagashada yar iyo midabaynta yar.
DC01-B: Dusha ugu fiican waa inay ka madax bannaanaato cilladaha laga yaabo inay saameeyaan muuqaalka isku midka ah ee rinjiga tayada sare leh ama dahaarka korantada. Oogada kale waa inay la kulantaa ugu yaraan tayada dusha A.
Goobaha ugu muhiimsan ee laga codsado qalabka DC01 waxaa ka mid ah: warshadaha baabuurta, warshadaha dhismaha, qalabka elektaroonigga ah iyo warshadaha qalabka guriga, ujeedooyinka qurxinta, cuntada qasacadaysan, iwm.

Faa'iidada ugu weyn
Saxan-qaadiddu waxay ka samaysan tahay xaashi kulul oo la dubay oo tayadeedu sarreyso sida alaab cayriin ah. Ka dib markii cutubka pickling ka saaro lakabka oksaydhka, gooyaa oo dhammeeyaa, tayada dusha iyo shuruudaha isticmaalka (inta badan qabow-sameeyey ama waxqabadka shaabadeynta) waxay u dhexeeyaan kuleyl-kulul iyo qabow-duuban Badeecada dhexdhexaadka ah ee u dhaxaysa taarikada ayaa ah beddelka ugu habboon ee qaar ka mid ah taarikada kulul-duuban iyo taarikada qabow-duubka. Marka la barbardhigo taarikada kulul ee kulul, faa'iidooyinka ugu muhiimsan ee taarikada pickled waa: 1. Tayada sare ee wanaagsan. Sababtoo ah taargooyinka la dubay ee kulul ayaa ka saaraya miisaanka oksaydhka dusha sare, tayada dusha birta ayaa la wanaajiyey, waxayna ku habboon tahay alxanka, saliidda iyo rinjiyeynta. 2. Saxnaanta cabbirkeedu waa sarreeyaa. Ka dib marka la barbardhigo, qaabka saxanka ayaa loo bedeli karaa ilaa xad, taas oo yareyneysa leexinta sinnaanta. 3. Hagaajinta dhamaystirka dusha sare oo kor u qaad saamaynta muuqaalka. 4. Waxay yarayn kartaa wasakhowga deegaanka ee ay keento qajaarka kala firdhisan ee isticmaalayaasha. Marka la barbardhigo xaashida qabow-duuban, faa'iidada xaashida la jarjaray ayaa ah in ay si wax ku ool ah u yareeyn karto kharashaadka iibka iyada oo la hubinayo shuruudaha tayada dusha sare. Shirkado badan ayaa soo bandhigay shuruudaha sare iyo sare ee waxqabadka sare iyo qiimaha jaban ee birta. Horumarka joogtada ah ee tignoolajiyada duubista birta, waxqabadka xaashida kulul ee duuban ayaa ku soo wajahan xaashida qabow-duuban, si "ku beddelka qabowga kulaylka" farsamo ahaan loo xaqiijiyo. Waxa la odhan karaa saxan-ku-salaysan waa badeecad leh qiime-dhammaan-qiimo-sare oo u dhexeeya saxanadda qabow-duuban iyo tan-kulul-lulaynta, waxaanay leedahay rajo horumar suuqeed oo wanaagsan. Si kastaba ha ahaatee, isticmaalka taarikada pickled ee warshadaha kala duwan ee dalkayga ayaa hadda bilaabay. Soo saarista taariko la jarjaray oo xirfad leh ayaa bilaabatay Sebtembar 2001 markii khadka wax soo saarka ee Baosteel la hawlgaliyay.
