EN10025-3, nambala: 1.8901 Dzina lachitsulo lili ndi magawo otsatirawa: Chilembo cha chizindikiro S: makulidwe okhudzana ndi zitsulo zosakwana 16mm zokolola zamphamvu: mtengo wotsika mtengo: Zokolola zosachepera Mikhalidwe yobweretsera: N imanena kuti kutentha kosachepera -50 madigiri kumayimiridwa ndi chilembo chachikulu L.
S460N, S460NL, S460N-Z35 Makulidwe, mawonekedwe, kulemera ndi kupatuka kovomerezeka.
Kukula, mawonekedwe ndi kupatuka kovomerezeka kwa mbale yachitsulo kudzayenderana ndi zomwe EN 10025-1 mu 2004.
S460N, S460NL, S460N-Z35 yobweretsera Ma mbale achitsulo nthawi zambiri amaperekedwa mumkhalidwe wabwinobwino kapena kugudubuzika mwachizolowezi pansi pamikhalidwe yomweyi.
S460N, S460NL, S460N-Z35 Chemical Composition of S460N, S460NL, S460N-Z35 chitsulo Kuphatikizika kwa Chemical (kusungunula kusungunuka) kudzagwirizana ndi tebulo ili (%).
S460N, S460NL, S460N-Z35 zofunikira zopangira mankhwala: Nb+Ti+V≤0.26;Cr+Mo≤0.38 S460N Melting Analysis Carbon Equivalent (CEV).
S460N, S460NL, S460N-Z35 Mechanical properties Zomwe zimagwiritsidwa ntchito ndi makina a S460N, S460NL, S460N-Z35 zidzakwaniritsa zofunikira pa tebulo ili: Zida zamakina za S460N (zoyenera kusinthasintha).
S460N, S460NL, S460N-Z35 mphamvu yamphamvu mumayendedwe abwinobwino.
Pambuyo annealing ndi normalizing, ndi mpweya zitsulo akhoza kupeza moyenera kapena pafupi yolinganizika dongosolo, ndipo pambuyo kuzimitsa, akhoza kupeza sanali Equilibrium kapangidwe.Choncho, pophunzira kapangidwe kake pambuyo pa chithandizo cha kutentha, osati chithunzi chachitsulo cha carbon phase komanso isothermal transformation curve (C curve) yachitsulo iyenera kutchulidwa.
Chithunzi chachitsulo cha carbon gawo chikhoza kusonyeza ndondomeko ya crystallization ya alloy pa kuzizira pang'onopang'ono, kapangidwe kameneka kutentha ndi kuchuluka kwa magawo, ndipo C curve ikhoza kusonyeza mapangidwe a chitsulo ndi mawonekedwe ena pansi pazikhalidwe zosiyanasiyana zozizira.C curve ndi yoyenera kuzizira kwa isothermal;Mzere wa CCT (austenitic continuous cooling curve) umagwira ntchito pazikhalidwe zozizirira mosalekeza.Pamlingo wina, C curve itha kugwiritsidwanso ntchito kuyerekeza kusintha kwa microstructure pakuzizira kosalekeza.
Pamene austenite itakhazikika pang'onopang'ono (yofanana ndi kuzirala kwa ng'anjo, monga momwe tawonetsera mkuyu. 2 V1), zinthu zosinthika zimakhala pafupi ndi dongosolo lofanana, lomwe ndi pearlite ndi ferrite.Ndi kuwonjezeka kwa kuzirala mlingo, ndiye, pamene V3> V2> V1, ndi undercooling wa austenite pang'onopang'ono kumawonjezera, ndipo kuchuluka kwa mpweya ferrite amakhala pang'onopang'ono, pamene kuchuluka kwa pearlite pang'onopang'ono ukuwonjezeka, ndipo dongosolo amakhala bwino.Panthawi imeneyi, ferrite yocheperako imagawidwa kwambiri pamalire a tirigu.
Chifukwa chake, kapangidwe ka v1 ndi ferrite + pearlite;Kapangidwe ka v2 ndi ferrite + sorbite;Microstructure ya v3 ndi ferrite + troostite.
Pamene mlingo wozizira ndi v4, ferrite yaing'ono ya network ndi troostite (nthawizina pang'ono ya bainite imatha kuwonedwa) imatenthedwa, ndipo austenite imasinthidwa makamaka kukhala martensite ndi troostite;Pamene kuzizira kwa v5 kumaposa kuzizira koopsa, chitsulocho chimasandulika kukhala martensite.
Kusintha kwachitsulo cha hypereutectoid ndi chofanana ndi chitsulo cha hypoeutectoid, ndi kusiyana komwe ferrite imayambira poyamba ndipo cementite imayambira poyamba.
