Imiterere yubukanishi bwa GB GCr15 yometseho ibyuma (bisanzwe mubyuma) bigaragara mumbonerahamwe ikurikira:
Umujinya | Tanga umusaruro | Modulus | Shear modulus | Ikigereranyo cya Poisson | Amashanyarazi |
MPa | Mpa | Gpa | Gpa | W / mK | |
520 | 415 Min | 140 | 80 | 0.27-0.30 | 46.6 |
Kuvura ubushyuhe Bifitanye isano
Buhoro buhoro ushyushye kuri 790-810 ℃ hanyuma wemere ibihe bihagije, reka ibyuma bishyushye neza, Hanyuma bikonje buhoro mumatanura. Inzira zitandukanye za annealing zizabona ubukana butandukanye.Icyuma cya GCr15 kizabona ibyuma MAX 248 HB (Gukomera kwa Brinell).
Gushyushya buhoro kugeza kuri 860 ° C, Noneho kuzimya amavuta ubone 62 kugeza 66 HRc gukomera. Ubushyuhe bwo hejuru: 650-700 ℃ , akonje mu kirere, kubona ubukana 22 kugeza 30HRC. Ubushyuhe buke: 150-170 ℃ , Ubukonje muri ari, shaka ubukana bwa 61-66HRC.
Icyuma cya GB GCr15 gishobora gushyuha gikora kuri 205 kugeza kuri 538 ° C, GCr15 Icyuma gishobora gukonja gikoreshwa hakoreshejwe tekiniki zisanzwe mubihe bidasanzwe cyangwa bisanzwe.
GB GCr15 ibyuma bikoreshwa cyane mubikorwa bitandukanye mubikoreshwa mubikoresho byimashini zizunguruka. Porogaramu zisanzwe nkimibiri ya valve, pompe na fitingi, umutwaro muremure wibiziga, bolts, imitwe ibiri yimitwe, ibyuma, moteri yaka imbere. Imashini zikoresha amashanyarazi, ibikoresho byimashini, ibimashini, ibikoresho bizunguruka ibyuma, imashini irambirana, imodoka ya gari ya moshi, hamwe n’imashini zicukura amabuye y'agaciro ku mupira w'icyuma, uruziga n'ikiganza, n'ibindi.
