Le khasiI-ASTM A992I-A992M -111111 (2015) Ukucacisa kuchazwa izigaba zensimbi ezigoqiwe ukuze zisetshenziswe ezinhlakeni zokwakha, izakhiwo zebhuloho, nezinye izakhiwo ezisetshenziswa kakhulu. I-Standard icacisa isilinganiso esisetshenziselwa ukunquma ukwakheka kwamakhemikhali okudingekayo kwezici zokuhlaziya okushisayo ezifana: ikhabhoni, i-manganese, i-phosphorus, isibabule, i-chromium, i-molybdenum, i-niobium, ne-thibium, nethusi. Izinga futhi licacisa izakhiwo ezicindezelayo ezidingekayo kwizinhlelo zokusebenza zokuhlola eziphakeme ezifana namandla ezithelo, amandla ashubile, kanye nokubumbana.
I-ASTM A992(FY = 50 KSI, FU = 65 KSI) ukucaciswa okuthandwa yiphrofayili yezigaba ezibanzi ze-Flange izigaba ezibanzi futhi manje zithatha indawoI-ASTM A36na-A572Ibanga 50 Ngaphezu kwalokho, kumanani alinganayo e-carbon afinyelela kumaphesenti angama-0,5, acacisa ukuthi i-decticity yokwakha ngamaphesenti angama-0.85. , kuthuthukisa ukushiswa kwensimbi e-carbon elingana amanani alinganayo aze afike ku-0.45 (0.47 amaphrofayili amahlanu eqenjini 4); kanye ne-ASTM A992 / A992M -11 (2015) kusebenza kuzo zonke izinhlobo zamaphrofayili ensimbi ezishisayo.
Umehluko phakathi kwe-ASTM A572 Grade 50 Izinto ezibonakalayo ze-ASTM A992 Ibanga lokuqukethwe
Izinto ze-ASTM A572 Ibanga le-50 liyafana ne-ASTM A992 Material kodwa kukhona umehluko. Izingxenye eziningi ezibanzi ze-flange ezisetshenzisiwe namuhla yiBanga le-ASTM A992. Ngenkathi i-ASTM A992 ne-ASTM A572 Ibanga 50 ngokuvamile liyafana, i-ASTM A992 liphakeme ngokwemigomo yokwakheka kwamakhemikhali kanye nokulawulwa kwempahla emishini.
I-ASTM A992 inenani lamandla okuthola isivuno kanye nenani lamandla okuthe xaxa, kanye namandla aphezulu wesivuno ekuvuseleleni amandla okuqina kanye nenani elilinganayo lekhabhoni. Ibanga le-ASTM A992 libiza kakhulu ukuthenga kune-ASTM A572 ibanga le-50 (ne-ASTM A36 ibanga elibanzi le-Flange.
