20CrMnTi (H) yotentha yozungulira zitsulo zozungulira

makhalidwe owuma zitsulo aloyi chida zitsulo, wabwino carburizing kutentha ndondomeko mankhwala ndi ntchito ya zitsulo pa ≤960 ℃ wabwino njere kapangidwe, ambiri ntchito kwa nthawi yaitali Kutentha carburizing kutentha, njere anakula palibe chizolowezi pang'ono yotsalira austenite pambuyo quenching Choncho, chitsulo chimakhala ndi mphamvu zambiri komanso kukana kuvala, ntchito yabwino kwambiri yodula, ntchito yaikulu ndi 20CrMnTi ndi 20CrNi zitsulo zofanana. Kuchulukira kwamphamvu σ ≥1080MPa, kutulutsa mphamvu σ ≥885MPa, elongation δ ≥10%, 45% kuchepetsa kutupa, kulimba kwamphamvu (kuvuta kwamphamvu) α ≥69J/ cm, kuuma ≤207mm kukula kwachitsanzo mpaka 5 HB, 5 mm kukula kwake.

GB 20CrMnTi GB/T 3077 Mechanical

Kapangidwe ka zitsulo za GB 20CrMnTi GB/T 3077 amatsimikizira kuchuluka kwa zinthu zothandiza ndikukhazikitsa moyo wantchito womwe ungayembekezere. Zimango zimagwiritsidwanso ntchito pothandizira kugawa ndi kuzindikira zinthu.

Kutentha mankhwala Zogwirizana

• Zowonjezera zazitsulo za 20CrMnTi Alloy Gearing

Pang'onopang'ono kutentha kwa 790-810 ℃ ndikulola nthawi zokwanira, lolani chitsulo chizitenthedwa bwino, Kenako kuziziritsa pang'onopang'ono mu ng'anjo. Njira zosiyanasiyana zomangira zidzapeza kuuma kosiyana.Chitsulo cha 20CrMnTi Gearing chidzapeza Kulimba MAX 248 HB (kulimba kwa Brinell).

• Kuzimitsa ndi kutentha kwa 20CrMnTi giya chitsulo

Kutenthetsa pang'onopang'ono mpaka 788 ° C, Kenako ikani ng'anjo yosambira yamchere sungani 1191 ℃ mpaka 1204 ℃。 kuzimitsa ndi mafuta kupeza 60 mpaka 66 Hrc kuuma. Kutentha kwakukulu kwa kutentha: 650-700 ℃, ozizira mumlengalenga, kupeza kuuma 22 mpaka 30HRC. Kutentha kutsika: 150-200 ℃, Kuzizira  mu ari, pezani kulimba kwa 61-66HRC.

• Ntchito yotentha ndi ntchito yozizira ya 20CrMnTi Alloy Gearing steel

Chitsulo cha GB 20CrMnTi chimatha kutenthedwa pa 205 mpaka 538°C, 20CrMnTi Bearing/Chitsulo choyatsa chimatha kugwira ntchito mozizira pogwiritsa ntchito njira wamba m'mikhalidwe yokhazikika kapena yokhazikika.
