DIN 17100 St52.3 tuubooyin dhismeed oo afar gees ah ayaa loo raray Australia.
DIN 17100 waa halbeeg lagu dabaqo qaybaha birta, birta birta, ulaha silig, alaab guriaan kala go 'lahayniyo welded, square iyo leydi qaybaha godan, foornada, iyo alaabta semi-dhammeeyay ee guud ahaan biraha qaab-dhismeedka kuwaas oo la keeno in xaalad kulul oo la sameeyay ama caadiga ah ka dib wax soo saarka.
St52.3 waa mid ka mid ah darajooyinka, lambarkuna waa 1.0570.
Ka hor inta aan la keenin, Botop waxa ay qabanqaabisaa shaqaale tayo leh oo xirfad leh si ay si taxadar leh u baaraan alaabta si loo hubiyo in tayada alaabadu ay si buuxda u buuxiso shuruudaha macaamiisha.
Marka hore, tayada dusha sare, ballaca, dhererka, dhererka, labajibnaanta, iyo cabbirrada kale ee muuqaalka ee tuubada birta qaab dhismeedka ayaa si taxadar leh loo kormeeraa si loo hubiyo u hoggaansanaanta heerarka iyo shuruudaha macaamiisha.
Marka xigta, sifooyinka kiimikada iyo farsamada ee tuubada birta qaab dhismeedka ayaa la hubiyaa.
TS EN 17100 St52.3 waxay leedahay shuruudaha soo socda ee isku dhafka kiimikada:
| Darajo | Halabuurka kiimikada % by wt. | ||||||||
| C | P | S | Cunsuryo dheeri ah oo isku darka nitrogen (tusaale ugu yaraan 0.020% Al ilaa tal) | ||||||

Halabuurka kiimikaad ee St52.3 waxaa lagu cabbiraa spectrometer, dhammaan walxaha ku jira waxa ay buuxinayaan shuruudaha macaamiisha marka loo eego shuruudaha lagu dabaqi karo.
Astaamaha makaanikada ee EN 17100 St52.3 inta badan waxaa ka mid ah xoogga xajinta iyo xoogga wax-soo-saarka, kuwaas oo lagu cabbiro tijaabada xajinta.

Ka dib marka la dhammeeyo dhammaan kormeerada iyo hubinta in tayada ay buuxisay shuruudaha caadiga ah, Shahaadada Imtixaanka Qalabka (MTC) ayaa la soo saaray. Ka dib, waxaa la diyaarinayaa maraakiibta iyo hawlaha la xidhiidha.
Tan iyo markii la aasaasay 2014, Botop Steel waxay noqotay shirkad hormuud u ah tubooyinka birta kaarboon ee waqooyiga Shiinaha, oo caan ku ah adeeggeeda wanaagsan, alaab tayo sare leh, iyo xalal dhammaystiran.
Dalbo kasta, Botop had iyo jeer waxay u hoggaansamaan istaraatiijiyada tayada la isku halleyn karo iyo qiimaha wanaagsan, annaga oo dooranayna inaan ku siino alaabada birta ah ee la isku halleyn karo.
