P235TR1 ndi chitoliro chachitsulo chomwe mankhwala ake nthawi zambiri amagwirizana ndi muyezo wa EN 10216-1.mankhwala chomera, zombo, kumanga mapaipi ndi wambazolinga zamakina engineering.
Malinga ndi muyezo, mankhwala opangidwa ndi P235TR1 amaphatikiza kaboni (C) mpaka 0.16%, silicon (Si) yofikira 0.35%, manganese (Mn) ali pakati pa 0.30-1.20%, phosphorous (P) ndi sulfure (S). ).) zomwe zili pamwambazi ndi 0.025% motsatira.Kuphatikiza apo, malinga ndi zofunikira, P235TR1 imathanso kukhala ndi zinthu zingapo monga chromium (Cr), mkuwa (Cu), faifi tambala (Ni) ndi niobium (Nb).Kuwongolera kwamankhwala awa kumatha kuwonetsetsa kuti mapaipi achitsulo a P235TR1 ali ndi zida zoyenera zamakina komanso kukana dzimbiri, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito m'mafakitale ena.
Kuchokera pamawonekedwe a mankhwala, mpweya wochepa wa P235TR1 umathandizira kukonza kuwotcherera ndi kusinthika kwake, ndipo zomwe zili ndi silicon ndi manganese zimathandizira kulimbitsa mphamvu zake komanso kukana dzimbiri.Kuphatikiza apo, phosphorous ndi sulfure zomwe zili ndi sulfure ziyenera kuyendetsedwa pamilingo yotsika kuti zitsimikizire kuyera kwazinthu komanso kusinthika.Kukhalapo kwa zinthu monga chromium, mkuwa, nickel ndi niobium kumatha kukhudza zinthu zina zamapaipi achitsulo, monga kukana kutentha kapena kukana dzimbiri.
Kuphatikiza pa kupanga mankhwala, njira zopangira, njira zochizira kutentha ndi zizindikiro zina zakuthupi za P235TR1 chitoliro chachitsulo ndizonso zofunika zomwe zimakhudza ntchito yake yomaliza.Kawirikawiri, mankhwala a P235TR1 chitoliro chachitsulo ndi chimodzi mwa zinthu zofunika kwambiri kuti zitsimikizidwe kuti zikugwirizana ndi zofunikira zoyenera komanso zingathe kukwaniritsa zolinga zaumisiri.
