Zinthu zakuthupi

Kachulukidwe: 7.7g/cm³; mphamvu yamphamvu: 590MPa; mphamvu zokolola: 245MPa; kukula: 15%; kuuma HBW: 269; kuzimitsa ndi kutentha kuuma: 55HRC.

Makhalidwe amakina

1.4112 ndi chitsulo chosapanga dzimbiri cha carbon martensitic. Mapangidwe ake amakina makamaka amaphatikizapo mphamvu, kuuma, kulimba, ndi zina zotero. Panthawi imodzimodziyo, chifukwa cha kulimba kwake bwino, mtundu wachitsulo uwu siwophweka kukumba ndipo ungagwiritsidwe ntchito m'madera ovuta kwambiri. Imalimbana ndi dzimbiri kuchokera kumlengalenga wofatsa, nthunzi wamadzi, ammonia, zinthu zambiri zamafuta ndi zinthu zachilengedwe, komanso malo osiyanasiyana ofooka acidic. Kutentha kwa annealing kumakhala kochepa kwambiri, ndipo kuuma pambuyo pozimitsa kumakhala kwakukulu. Kuuma nthawi zambiri kumafika HRC56-58. Ili ndi kukana bwino kwa dzimbiri (maginito) komanso kulimba kolimba.

Malo ofunsira

Chifukwa chitsulo chosapanga dzimbiri cha 1.4112 chili ndi mphamvu zabwino kwambiri zolimbana ndi dzimbiri komanso makina, chimagwiritsidwa ntchito kwambiri mumafuta, makampani opanga mankhwala, zomangamanga zam'madzi, magalimoto, chakudya ndi madera ena. M'mafakitale amafuta ndi mankhwala, chifukwa cha kukana kwake bwino kwa dzimbiri, amagwiritsidwa ntchito popanga ma reactors, mapaipi ndi zida zina. M'munda wa uinjiniya wam'madzi, amagwiritsidwa ntchito popanga zigawo zazikulu za zombo ndi nsanja zakunyanja. M'munda wamagalimoto, amagwiritsidwa ntchito popanga zinthu monga makina otulutsa mpweya ndi zomangira. M'munda wa chakudya, amagwiritsidwa ntchito popanga zida zakukhitchini ndi zida zopangira chakudya chifukwa chaukhondo wake.

Kugwira ntchito

The ndondomeko katundu 1.4112 zitsulo zosapanga dzimbiri makamaka monga kuwotcherera, kutentha mankhwala ndi processing katundu. Mtundu wachitsulo uwu uli ndi ntchito yabwino yowotcherera ndipo ukhoza kuwotcherera pogwiritsa ntchito njira zosiyanasiyana zowotcherera. Kuchiza kutentha kumatha kupititsa patsogolo makina ake komanso kukana kwa dzimbiri, koma chisamaliro chiyenera kutengedwa kuti tipewe kusweka kapena kupunduka komwe kumachitika chifukwa cha kutentha kapena kuzizira kwambiri. Ili ndi magwiridwe antchito abwino ndipo imatha kugwiritsidwa ntchito kutembenuza, mphero, kubowola, kugogoda ndi ntchito zina zopangira. Zoipa zake ndi zomata ndipo zimatentha mofulumira, koma zimakhala zosavuta kuchita mchenga kusiyana ndi zitsulo zonse za carbon ndipo zimakhala zosavuta kuzidula ndi macheka.

Kulondola kwapamwamba kwambiri ndi 0.03mm, kusalala kwambiri ndi Rz1um, ndipo kukhazikika kwa malo onse ozungulira akunja kuli mkati mwa 0.03mm.

Kukonza

Kuponya: kugwiritsa ntchito sing'anga kutentha sera anataya sera mwatsatanetsatane kuponyera.
