Imibhobho yentsimbi eyakhiwe ngonxantathu yeDIN 17100 St52.3 yathunyelwa eOstreliya.
I-DIN 17100 isetyenziswa ngokuqhelekileyo kwiindawo zentsimbi, iibha zentsimbi, iintonga zentsimbi, iimveliso ezithe tyabaingenamthungokunye namacandelo adibeneyo, anesikwere kunye namacala angxande, izinto zokugquma, kunye neemveliso ezigqityiweyo kancinci kwiintsimbi zesakhiwo ngokubanzi ezithunyelwa kwimeko eshushu okanye eqhelekileyo emva kokuveliswa.
I-St52.3 yenye yeeklasi, kwaye inombolo yezinto ezibonakalayo yi-1.0570.
Ngaphambi kokuba ithunyelwe, iBotop ilungiselela abasebenzi abangochwephesha ukuba bahlole ngononophelo iimveliso ukuqinisekisa ukuba umgangatho wemveliso uyahlangabezana ngokupheleleyo neemfuno zabathengi.
Okokuqala, umgangatho womphezulu, ububanzi, ukuphakama, ubude, isikwere, kunye neminye imilinganiselo yembonakalo yombhobho wesinyithi wolwakhiwo ihlolwa ngononophelo ukuqinisekisa ukuthotyelwa kwemigangatho kunye neemfuno zabathengi.
Okulandelayo, iipropati zeekhemikhali kunye nezoomatshini zombhobho wesinyithi wesakhiwo ziyajongwa.
I-EN 17100 St52.3 ineemfuno ezilandelayo zokwakheka kweekhemikhali:
| Ibanga | Ukwakheka kweekhemikhali kwi-% nge-wt. | ||||||||
| C | P | S | Izinto ezongezelelweyo ezidibanisa i-nitrogen (umz. ubuncinane i-0.020% Al ukuya kwi-total) | ||||||
| ubukhulu bemveliso nge-mm | |||||||||
| ≤16 | ＞16 ≤30 | ＞30 ≤40 | ＞40 ≤63 | ＞63 ≤100 | ＞100 | ||||
| EN 17100 St52.3 | Ubuninzi obuyi-0.20 | Ubuninzi obuyi-0.20 | Ubuninzi obuyi-0.22 | Ubuninzi obuyi-0.22 | Ubuninzi obuyi-0.22 | ngesivumelwano | Ubuninzi be-0.040 | Ubuninzi be-0.040 | Ewe |
Ukwakheka kweekhemikhali zeSt52.3 kulinganiswa nge-spectrometer, kwaye zonke izinto eziqulethwe kwi-element ziyahlangabezana neemfuno zabathengi xa kuthelekiswa neemfuno ezifanelekileyo.
Iimpawu zoomatshini ze-EN 17100 St52.3 ziquka ikakhulu amandla okutsalwa kunye namandla okukhupha, ezilinganiswa ngovavanyo lokutsalwa.
| Ibanga | Amandla okuxinana Rm | Inqaku eliphezulu le-ReH | |||||||
| ubukhulu bemveliso nge-mm | ubukhulu bemveliso nge-mm | ||||||||
| ＜3 | ≥3 ≤100 | ＞100 | ≤16 | ＞16 ≤30 | ＞30 ≤40 | ＞40 ≤63 | ＞63 ≤100 | ＞100 | |
| EN 17100 St52.3 | 510 - 680 MPa | 490 - 630 MPa | ngesivumelwano | 355 | 345 | 335 | 325 | 315 | ngesivumelwano |
Emva kokugqiba lonke uhlolo nokuqinisekisa ukuba umgangatho uyahlangabezana neemfuno ezisemgangathweni, kukhutshwa iSatifikethi soVavanyo lweMpahla (MTC). Emva koko, kwenziwa amalungiselelo okuthunyelwa kwempahla kunye nemisebenzi enxulumene nayo.
Ukususela oko yasekwa ngo-2014, iBotop Steel ibe ngumthengisi ophambili wemibhobho yentsimbi yekhabhoni kumantla eTshayina, eyaziwa ngenkonzo yayo egqwesileyo, iimveliso ezikumgangatho ophezulu, kunye nezisombululo ezibanzi.
Kwi-odolo nganye, iBotop isoloko ilandela icebo lomgangatho othembekileyo kunye namaxabiso afanelekileyo, ikhetha thina ukuba sikunike iimveliso zepayipi yentsimbi ezithembekileyo.
