I-P235TR1 yimbhobho yentsimbi equlathe iikhemikhali ezihambelana nomgangatho we-EN 10216-1.isityalo seekhemikhaliiinqanawa, ukwakhiwa kwemibhobho kunye neenkonzo eziqhelekileyoiinjongo zobunjineli boomatshini.

Ngokwemigangatho, ukwakheka kweekhemikhali zeP235TR1 kuquka umxholo wekhabhoni (C) ukuya kuthi ga kwi-0.16%, umxholo wesilicon (Si) ukuya kuthi ga kwi-0.35%, umxholo wemanganese (Mn) phakathi kwe-0.30-1.20%, umxholo wephosphorus (P) kunye nesulfure (S). ) ngu-0.025% ophezulu ngokwahlukeneyo. Ukongeza, ngokweemfuno ezisemgangathweni, ukwakheka kweP235TR1 kusenokuba nezixa ezincinci zezinto ezifana ne-chromium (Cr), i-copper (Cu), i-nickel (Ni) kunye ne-niobium (Nb). Ulawulo lwezi khemikhali lunokuqinisekisa ukuba imibhobho yentsimbi yeP235TR1 ineempawu ezifanelekileyo zoomatshini kunye nokumelana nokugqwala, okwenza ukuba ifaneleke ukusetyenziswa kwezinye izicelo ezithile zoshishino.

Ngokwembono yokwakheka kweekhemikhali, umxholo we-P235TR1 wekhabhoni ephantsi unceda ekuphuculeni ukudityaniswa kwayo kunye nokucutshungulwa kwayo, kwaye umxholo wayo we-silicon kunye ne-manganese unceda ekuphuculeni amandla ayo kunye nokumelana nokugqwala. Ukongeza, umxholo we-phosphorus kunye ne-sulfur kufuneka ulawulwe kumanqanaba aphantsi ukuqinisekisa ubunyulu bezinto kunye nokucutshungulwa kwazo. Ubukho bezinto ezilandelelanayo ezifana ne-chromium, i-copper, i-nickel kunye ne-niobium bunokuba nefuthe kwiimpawu ezithile zemibhobho yentsimbi, njengokumelana nobushushu okanye ukumelana nokugqwala.

Ukongeza kwimilo yeekhemikhali, inkqubo yokuvelisa, iindlela zonyango lobushushu kunye nezinye izalathisi zokusebenza ezibonakalayo zombhobho wentsimbi we-P235TR1 nazo zizinto ezibalulekileyo ezichaphazela ukusebenza kwawo kokugqibela. Ngokubanzi, ukwakheka kweekhemikhali zombhobho wentsimbi we-P235TR1 yenye yezinto ezibalulekileyo ukuqinisekisa ukuba iyahlangabezana neemfuno zemigangatho efanelekileyo kwaye inokuhlangabezana neenjongo ezithile zobunjineli.
