SAE8620H Icyuma Cyuzuye Cyuma / GB 20CrNiMo Icyuma
Ibiranga
8620 ibyuma bivanze bigizwe na (muburyo bwo kugabanuka kwijanisha) icyuma, karubone, silikoni, molybdenum, manganese, nikel, chromium, sulfure na fosifore.Ibi bikoresho bigomba kuba muburemere bwijana kugirango habeho 8620.Birasabwa ko ibyuma byakomezwa na carburisation bigakurikirwa namavuta, bitandukanye namazi, kuzimya.Ifite uburinganire buringaniye ku byuma bivangwa na litiro 28 kuri santimetero kare, nubwo imbaraga zayo zingana - uburemere bushobora gufata mbere yo kumeneka - ni hasi, kuri 536.4 Mpa.Impuzandengo yingufu zingana zibyuma ni 758 kugeza 1882 Mpa.
Iyo 8620 ivanze ikozwe neza - ishyutswe nubushyuhe bwagenwe hanyuma igahura na agent irimo karubone, inzira ikongeramo ikindi cyuma cya karubone hanze yicyuma, bityo igakomera - ikoreshwa mugukora imashini nkiyi ibice nkibikoresho, crankshafts, nimpeta zi bikoresho.Carburized 8620 alloy irakomeye kandi iramba, niyo mpamvu ikunzwe kubice.

SAE8620H Icyuma gisaba ibyuma
Bikunze gukoreshwa mugukora ibice byingenzi bifite imbaraga nyinshi na plastike nziza, no mugukora ibice byingenzi nibisabwa byihariye nyuma yo kuvura nitriding:
Ibirindiro biremereye cyane, ibihuru, Abakurikira Cam, bambara amapine, ibyuma, amasoko, ibikoresho na shitingi, Imbwa za Clutch, Compressor Bolts, Extractors, Fana Shafts, Ibikoresho biremereye cyane, Amapompo, Spockets, Tappets, Wambara Amapine, Imiyoboro ya Wire nibindi. . Cyangwa irashobora gukoreshwa murwego rwohejuru rwimikorere idakomerekejwe ariko ikoresheje gukomera no kurakara.Ikoreshwa cyane ninganda zose zinganda kubice na shaft bisaba kwihanganira kwambara hejuru, imbaraga zikomeye hamwe ningaruka.
