ʻO Cr12MoV nā kaola kila ʻōwili wela

He kiʻekiʻe ka paʻakikī o ke kila Cr12MoV, a ʻo ka poʻe me ka ʻāpana keʻa o 300 a 400 mm a i ʻole ka liʻiliʻi hiki ke kinai loa.
Hiki iā ia ke mālama i ka paʻakikī maikaʻi a me ke kūpaʻa ʻana ma 300 ～ 400 ℃, ʻoi aku kona paʻakikī ma mua o ke kila Cr12, a he liʻiliʻi kona hoʻololi ʻana i ka wā e hoʻopau ai. Hiki ke hoʻohana ʻia no ka hana ʻana i nā ʻano like ʻole a me nā mea hana me nā ʻāpana keʻa nui, nā ʻano paʻakikī, a kū i nā ukana hopena nui. No ka laʻana, make kuʻi me nā ʻano paʻakikī, hoʻokomo i nā make paʻakikī, make ke kaha kiʻi hohonu, make ke kaha kiʻi uea, pā uwea wili, make ka extrusion anu, ʻoki ʻoki anu, ʻoki pōʻai, mea hana maʻamau, mea ana, etc.
ʻO ke kila Cr12MoV he kila kila kiʻekiʻe, molybdenum lysic kiʻekiʻe. ʻOi aku ka haʻahaʻa o kāna ʻike kalapona ma mua o ke kila Crl2, a ua hoʻohui ʻia me nā mea molybdenum a me vanadium, kahi e hoʻomaikaʻi maikaʻi ai i nā waiwai hana wela o ke kila, ka paʻakikī o ka hopena a me ka hāʻawi ʻana i ka carbide. ʻO ke kila ke kūpaʻa lole kiʻekiʻe, hardenability, hardenability, toughness, thermal stability, compressive strength, a me ka micro deformation, maikaʻi loa ka hana piha a me ka nui adaptability. ʻO 520 ℃ ka wela wela. Aia ma lalo o 4mm ka nui i ʻoki ʻia a hiki ke paʻakikī loa. ʻO ka pale pale o kēia kila he 3 ~ 4 mau manawa kiʻekiʻe ma mua o ka mea hana haʻahaʻa haʻahaʻa haʻahaʻa, a he liʻiliʻi ka nui quenching. ʻO ka hohonu paʻakikī: ʻaila kinai 200 ~ 300mm.
I ka wā o ke kaʻina hana crystallization, ua hoʻokumu ʻia ka nui o nā carbide keʻokeʻo eutectic (ʻo ka hapa o ka mea carbonized ma kahi o 20%, a ʻo ka mahana eutectic ma kahi o 1150 ° C). ʻO kēia mau carbide he paʻakikī a palupalu. ʻOiai ua haki ʻia nā carbide i kekahi pae ma hope o ka ʻōwili ʻana o ka billet, ua māhele ʻia nā carbide i nā kaula, nā papa, nā poloka, a me nā puʻu ma ka ʻaoʻao o ka ʻōwili ʻana, a piʻi ka degere o ka hoʻokaʻawale ʻana me ke anawaena o ke kila.
