Nthawi zonse pamakhala chida choyenera pantchitoyo, ndipo nthawi zambiri, pamafunika chitsulo choyenera kupanga chidacho.A2 ndiye gulu lodziwika bwino lazitsulo zomwe zimagwiritsidwa ntchito popanga zida zopangira zitsulo, matabwa, ndi zida zina.A2 medium-carbon chromium alloy steel ndi membala wa gulu lazitsulo lozizira, losankhidwa ndi American Iron and Steel Institute (AISI), yomwe imaphatikizapo O1 low-carbon steel, A2 chitsulo ndi D2 high-carbon high-chromium steel.

Cold work tool chitsulo ndi chisankho chabwino pazigawo zomwe zimafuna kulimba kwa kukana komanso kulimba.Amagwiranso ntchito bwino pazigawo zomwe zimafunikira kuchepa pang'ono kapena kupotoza panthawi yowumitsa.

Kukana kuvala kwachitsulo cha A2 ndikwapakatikati pakati pa O1 ndi D2 chitsulo, ndipo kumakhala ndi makina abwino kwambiri opangira ndikupera.A2 ndi yolimba kuposa chitsulo cha D2, ndipo imakhala ndi mawonekedwe abwinoko pambuyo pa chithandizo cha kutentha kuposa chitsulo cha O1.

Mwachidule, chitsulo cha A2 chimayimira bwino pakati pa mtengo ndi mawonekedwe a thupi, ndipo nthawi zambiri amaonedwa ngati cholinga chachikulu, chitsulo cha chilengedwe chonse.

Kupanga

Chitsulo cha A2 ndizomwe zimagwiritsidwa ntchito kwambiri pamagulu Amagulu A zitsulo zolembedwa mu ASTM A682 standard, zomwe zimatchedwa "A" kuti ziwumitse mpweya.

Panthawi yochizira kutentha, mpweya wapakati wa 1% umalola kuti chitsulo cha A2 chikhale cholimba pozizira mumpweya wokhazikika - zomwe zimalepheretsa kupotoza ndi kusweka komwe kungayambike chifukwa cha kuzimitsidwa kwa madzi.

Ma chromium apamwamba (5%) a chitsulo cha A2, pamodzi ndi manganese ndi molybdenum, amalola kuti akwaniritse kuuma kwathunthu kwa 57-62 HRC m'magawo okhuthala (ma mainchesi 4 m'mimba mwake) - kuwapatsa kukhazikika kwabwino ngakhale pazigawo zazikulu.

Mapulogalamu

Chitsulo cha A2 chimapezeka m'njira zingapo, kuphatikiza masikweya, ozungulira, komanso osalala.Zinthu zosunthika kwambirizi zitha kugwiritsidwa ntchito pazida zosiyanasiyana zomwe zimafuna kukana kuvala, monga nyundo zamakampani, mipeni, slitters, nkhonya, zida, ndi zida zodulira matabwa.

Pazoyikapo ndi masamba, chitsulo cha A2 chimakana kudulidwa kuti chikhale chotalikirapo, nthawi zambiri chimapanga chisankho chopanda ndalama kuposa chitsulo chamtundu wamtundu wa D2 wapamwamba kwambiri.

Nthawi zambiri amagwiritsidwa ntchito pobisa ndi kupanga ulusi wodzigudubuza, kusindikiza kufa, kudula kufa, jekeseni nkhungu imafa, mandrels, nkhungu, ndi zopota.

Shanghai Histar Metalimapereka zida zachitsulo za A2 mu lalikulu, lathyathyathya komanso lozungulira mosiyanasiyana.Lumikizanani nafe kuti mupeze mtengo kapena pitani patsamba lathu.
