Cr12MoV e chesang e pota-potiloeng ke litšepe tse chitja

Cr12MoV tšepe e thatafalloa haholo, 'me ba nang le karolo ea 300 ho isa ho 400 mm kapa ka tlase ba ka tingoa ka botlalo.
E ka boloka boima bo botle 'me ea apara ho hanyetsa ho 300 ～ 400 ℃, boima ba eona bo phahame ho feta tšepe ea Cr12, 'me phetoho ea eona ea molumo ha e fokotsehe nakong ea ho tima. E ka sebelisoa ho etsa liforomo le lisebelisoa tse fapaneng tse nang le likarolo tse kholo tsa sefapano, libopeho tse rarahaneng, le ho mamella meroalo e meholo ea tšusumetso. Ka mohlala, ho phunya ho shoa ka libopeho tse rarahaneng, ho kenngoa holim'a li-dies e rarahaneng, setšoantšo se tebileng sa tšepe se shoa, setšoantšo sa terata se shoa, poleiti ea terata e nang le khoele, li-extrusion tse batang li shoa, lisekere tse batang tsa ho itšeha, lisakha tse chitja, lisebelisoa tse tloaelehileng, lisebelisoa tsa ho lekanya, joalo-joalo.
Cr12MoV tšepe ke tšepe e phahameng ea carbon, high-molybdenum lysic. Likahare tsa eona tsa khabone li tlase haholo ho feta tsa tšepe ea Crl2, 'me li eketsoa ka likarolo tsa molybdenum le vanadium, tse ntlafatsang haholo thepa ea ts'ebetso ea mocheso oa tšepe, ho ba le tšusumetso e matla le kabo ea carbide. Tšepe e na le khanyetso e phahameng ea ho roala, ho thatafala, ho thatafala, ho thatafala, botsitso ba mocheso, matla a ho hatella, hammoho le micro deformation, ts'ebetso e babatsehang e pharaletseng le ho ikamahanya le maemo ho pharaletseng. Mocheso o nolofatsang mocheso ke 520 ℃. Boholo ba sehiloeng bo ka tlase ho 4mm mme bo ka thatafatsoa ka botlalo. Khanyetso ea ho roala ha tšepe ena e phahame ka makhetlo a 3 ~ 4 ho feta ea tšepe ea lisebelisoa tse tlaase, 'me molumo oa ho tima o monyenyane. Ho thatafatsa botebo: ho tima oli 200 ~ 300mm.
Nakong ea ts'ebetso ea crystallization, palo e kholo ea li-carbide tse tšoeu tsa eutectic li thehoa (karolo ea ntho e entsoeng ka carbonized e ka bang 20%, 'me mocheso oa eutectic o ka bang 1150 ° C). Li-carbides tsena li thata haholo ebile li brittle. Le hoja li-carbides li robehile ho isa tekanyong e itseng ka mor'a hore li-billet li theohe, li-carbides li ajoa ka lihlopha, li-slabs, li-blocks le liqubu ho latela tataiso ea ho pota, 'me tekanyo ea ho arohana e eketseha ka bophara ba tšepe.
