Cr12MoV panas digulung baja buleud bar

baja Cr12MoV boga hardenability tinggi, sarta maranéhanana jeung cross-bagian 300 nepi ka 400 mm atawa kirang bisa sagemblengna quenched.
Bisa ngajaga karasa alus sarta lalawanan ngagem dina 300 ~ 400 ℃, kateguhan na leuwih luhur batan baja Cr12, sarta robah volume na minimal salila quenching. Éta tiasa dianggo pikeun ngadamel rupa-rupa kapang sareng alat-alat anu ageung cross-bagian, bentuk kompleks, sareng tahan beban dampak anu ageung. Contona, punching mati kalayan wangun kompléks, inserts on maot kompléks, baja jero gambar maot, kawat gambar maot, threaded plat kawat, tiis Tonjolan maot, gunting motong tiis, saws sirkular, parabot baku, alat ukur, jsb.
Baja Cr12MoV nyaéta baja lysic tinggi-karbon, molybdenum luhur. Eusi karbon na jauh leuwih handap tina baja Crl2, sarta eta ditambahkeun kalawan molybdenum na vanadium elemen, nu nyata ngaronjatkeun sipat processing termal baja urang, dampak kateguhan sarta distribusi carbide. baja ngabogaan lalawanan maké tinggi, hardenability, hardenability, kateguhan, stabilitas termal, kakuatan compressive, kitu ogé deformasi mikro, kinerja komprehensif alus teuing jeung adaptability éksténsif. Suhu softening panas nyaéta 520 ℃. Ukuran cut-off di handap 4mm sarta bisa sagemblengna hardened. Résistansi ngagem baja ieu 3 ~ 4 kali langkung luhur tibatan baja alat anu kakuatan rendah, sareng volume quenching alit. Jero hardening: minyak quenching 200 ~ 300mm.
Salila prosés kristalisasi, sajumlah ageung karbida bodas eutektik kabentuk (fraksi zat karbonisasi sakitar 20%, sareng suhu eutektik sakitar 1150 °C). Karbida ieu teuas pisan sareng rapuh. Sanaos karbida pegat kana tingkat anu tangtu saatos gulung billet, karbida disebarkeun dina pita, slabs, blok, sareng tumpukan sapanjang arah ngagulung, sareng darajat pamisahan ningkat kalayan diaméter baja.
