Cr12MoV hot rolled baja babak bar

Baja Cr12MoV nduweni hardenability dhuwur, lan sing duwe bagean salib 300 nganti 400 mm utawa kurang bisa dipateni.
Bisa njaga kekerasan sing apik lan resistensi nyandhang ing 300 ~ 400 ℃, kekuwatane luwih dhuwur tinimbang baja Cr12, lan owah-owahan volume minimal sajrone quenching. Bisa digunakake kanggo nggawe macem-macem cetakan lan alat kanthi bagean salib gedhe, bentuk kompleks, lan tahan beban impact gedhe. Contone, pukulan mati karo wangun Komplek, sisipan ing mati Komplek, baja jero drawing mati, kabel drawing mati, threaded piring kabel, mati extrusion kadhemen, gunting nglereni kadhemen, saws bunder, alat standar, alat ukur, etc.
Baja Cr12MoV minangka baja lysic dhuwur-karbon, molibdenum dhuwur. Isi karbon luwih murah tinimbang baja Crl2, lan ditambah karo unsur molybdenum lan vanadium, sing ningkatake sifat pangolahan termal baja, ketangguhan impact lan distribusi karbida. Baja kasebut nduweni resistensi nyandhang dhuwur, hardenability, hardenability, kateguhan, stabilitas termal, kekuatan compressive, uga deformasi mikro, kinerja lengkap banget lan daya adaptasi ekstensif. Suhu softening panas yaiku 520 ℃. Ukuran cut-off ngisor 4mm lan bisa rampung hardened. Ketahanan nyandhang baja iki 3 ~ 4 kaping luwih dhuwur tinimbang baja alat sing kurang kekuatan, lan volume quenching cilik. Hardening ambane: lenga quenching 200 ~ 300mm.
Sajrone proses kristalisasi, akeh karbida putih eutektik dibentuk (fraksi zat karbonisasi kira-kira 20%, lan suhu eutektik kira-kira 1150 ° C). Karbida iki atos lan rapuh. Sanajan karbida rusak nganti tingkat tartamtu sawise rolling billet, karbida disebarake ing pita, slab, pamblokiran, lan tumpukan ing sadawane arah rolling, lan derajat segregasi mundhak kanthi diameter baja.
