Cr12MoV gbona ti yiyi irin yika ifi

Irin Cr12MoV ni lile lile, ati awọn ti o ni apakan agbelebu ti 300 si 400 mm tabi kere si le ti parun patapata.
O le ṣetọju líle ti o dara ati wọ resistance ni 300 ~ 400 ℃, lile rẹ ga ju irin Cr12 lọ, ati iyipada iwọn didun rẹ jẹ iwonba lakoko pipa. O le ṣee lo lati ṣe ọpọlọpọ awọn apẹrẹ ati awọn irinṣẹ pẹlu awọn apakan agbelebu nla, awọn apẹrẹ eka, ati koju awọn ẹru ipa nla.

Irin Cr12MoV jẹ erogba-giga, irin lysic molybdenum giga. Akoonu erogba rẹ kere pupọ ju ti irin Crl2, ati pe o jẹ afikun pẹlu molybdenum ati awọn eroja vanadium, eyiti o ṣe ilọsiwaju awọn ohun-ini iṣelọpọ igbona ti irin, ipa lile ati pinpin carbide. Irin naa ni resistance yiya ti o ga, lile, lile, lile, iduroṣinṣin gbona, agbara compressive, bakanna bi abuku bulọọgi, iṣẹ pipe ti o dara julọ ati isọdọtun lọpọlọpọ. Awọn iwọn otutu rirọ ooru jẹ 520 ℃. Iwọn gige ti o wa ni isalẹ 4mm ati pe o le jẹ lile patapata. Iduro wiwọ ti irin yii jẹ awọn akoko 3 ~ 4 ti o ga ju ti irin-ọpa irin-kekere, ati iwọn didun parẹ jẹ kekere. Ijinle lile: epo quenching 200 ~ 300mm.
Lakoko ilana crystallization, nọmba nla ti awọn carbide funfun eutectic ti ṣẹda (ida nkan ti carbonized jẹ nipa 20%, ati iwọn otutu eutectic jẹ nipa 1150°C). Awọn carbides wọnyi jẹ lile ati brittle. Botilẹjẹpe awọn carbides ti fọ si iwọn kan lẹhin yiyi billet, awọn carbides ti pin ni awọn ẹgbẹ, awọn pẹlẹbẹ, awọn bulọọki, ati awọn piles lẹgbẹẹ itọsọna yiyi, ati iwọn ipinya pọ si pẹlu iwọn ila opin irin naa.
