I-P235TR1 yimathiriyeli yombhobho wentsimbi okwakhiwa kweekhemikhali ngokubanzi kuhambelana nomgangatho we-EN 10216-1.isityalo sekhemikhali, iinqanawa, ukwakhiwa kwemibhobho kunye nokuqhelekileyoiinjongo zobunjineli boomatshini.
Ngokomgangatho, ukubunjwa kweekhemikhali ze-P235TR1 kubandakanya i-carbon (C) umxholo ukuya kwi-0.16%, i-silicon (Si) umxholo ukuya kwi-0.35%, umxholo we-manganese (Mn) phakathi kwe-0.30-1.20%, i-phosphorus (P) kunye nesulfure (S) ).) umxholo ubuninzi be-0.025% ngokulandelanayo.Ukongeza, ngokweemfuno eziqhelekileyo, ukubunjwa kwe-P235TR1 kunokuqulatha amanani omkhondo wezinto ezinjenge-chromium (Cr), ubhedu (Cu), i-nickel (Ni) kunye ne-niobium (Nb).Ukulawulwa kwezi zakhiwo zeekhemikhali kunokuqinisekisa ukuba iipayipi zensimbi ze-P235TR1 zineepropati ezifanelekileyo zoomatshini kunye nokumelana nokubola, okwenza ukuba zilungele ukusetyenziswa kwezinye izicelo ezithile zoshishino.
Ukusuka kumbono wokwakheka kweekhemikhali, umxholo wekhabhoni ophantsi we-P235TR1 unceda ekuphuculeni i-weldability kunye ne-processability, kunye ne-silicon kunye nomxholo we-manganese unceda ukuphucula amandla ayo kunye nokuxhathisa ukubola.Ukongezelela, umxholo we-phosphorus kunye ne-sulfure kufuneka ulawulwe kumanqanaba aphantsi ukuze kuqinisekiswe ukucoceka kwezinto kunye nokuqhubekeka.Ubukho bezinto zokulandelela ezifana ne-chromium, ithusi, i-nickel kunye ne-niobium ingaba nefuthe kwiipropati ezithile zemibhobho yensimbi, njengokumelana nokushisa okanye ukuxhathisa ukubola.
Ukongeza kwimichiza yeekhemikhali, inkqubo yokuvelisa, iindlela zokunyanga ukushisa kunye nezinye izibonakaliso zokusebenza komzimba we-P235TR1 umbhobho wensimbi nazo zizinto ezibalulekileyo ezichaphazela ukusebenza kwayo kokugqibela.Ngokuqhelekileyo, ukubunjwa kweekhemikhali ze-P235TR1 ipayipi yensimbi yenye yezinto eziphambili zokuqinisekisa ukuba ihlangabezana neemfuno zemigangatho efanelekileyo kwaye inokuhlangabezana neenjongo ezithile zobunjineli.
