20CrMnTi (H) ibyuma bizengurutse ibyuma bizunguruka

Ibiranga ibyuma bikomye ibyuma bivangwa nicyuma, uburyo bwiza bwo gutunganya ubushyuhe bwa carburizing hamwe nigikorwa cyicyuma kuri 60960 structure imiterere yingano nziza, ikunze gukoreshwa mubushyuhe bwigihe kirekire bwo gushyushya carburizing, ingano ntizakuze cyane austenite isigaye nyuma yo kuzimya, kubwibyo, ibyuma bifite imbaraga nyinshi no kwambara birwanya, imikorere myiza yo gukata, imikorere nyamukuru na 20CrMnTi na 20CrNi ibyuma bisa. Imbaraga zingutu σ ≥1080MPa, imbaraga zitanga σ 85885MPa, kurambura δ ≥10%, 45% kugabanya kubyimba, gukomera kwingaruka (gukomera)

GB 20CrMnTi GB / T 3077 Umukanishi

Imiterere yubukanishi bwa GB 20CrMnTi GB / T 3077 ibyuma byerekana intera yingirakamaro yibikoresho kandi bigashyiraho ubuzima bwa serivisi bushobora guteganijwe. Ibikoresho bya mashini nabyo bikoreshwa mugufasha gutondeka no kumenya ibikoresho.

Kuvura ubushyuhe Bifitanye isano

• Annealing ya 20CrMnTi Alloy Gearing ibyuma

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 20CrMnTi Gearing ibyuma bizabona Hardness MAX 248 HB （Gukomera kwa Brinell）.

• Kuzimya n'ubushyuhe bwa 20CrMnTi ibyuma byuma

Gushyushya buhoro kugeza kuri 788 ° C, Noneho shyira mu itanura-umunyu wogumamo komeza 1191 ℃ kugeza 1204 ℃。 kuzimya amavuta ubone 60 kugeza 66 HRc gukomera. Ubushyuhe bwo hejuru: 650-700 ℃ ， akonje mu kirere, kubona ubukana 22 kugeza 30HRC. Ubushyuhe buke: 150-200 ℃ ol Ubukonje muri ari, shaka ubukana bwa 61-66HRC.

• Akazi gashyushye nakazi gakonje ka 20CrMnTi Alloy Gearing ibyuma

GB 20CrMnTi ibyuma birashobora gushyuha bikora kuri 205 kugeza kuri 538 ° C, 20CrMnTi Gutwara / Gukoresha ibyuma birashobora gukonja bikoreshwa hakoreshejwe tekiniki zisanzwe mubihe byateganijwe cyangwa bisanzwe.
