Cr12MoV kub dov steel puag ncig tuav

Cr12MoV steel muaj qhov hardenability siab, thiab cov uas muaj ntu ntu ntawm 300 mus rau 400 hli lossis tsawg dua tuaj yeem ua kom tiav.
Nws muaj peev xwm tuav tau zoo hardness thiab hnav tsis kam ntawm 300 ~ 400 ℃, nws toughness yog siab dua Cr12 steel, thiab nws qhov ntim hloov yog tsawg heev thaum quenching. Nws tuaj yeem siv los tsim ntau yam pwm thiab cov cuab yeej nrog cov ntu loj, cov duab nyuaj, thiab tiv taus qhov cuam tshuam loj. Piv txwv li, xuas nrig ntaus tuag nrog cov duab tsis yooj yim, ntxig rau ntawm txoj kev tuag, steel sib sib zog nqus kos tuag, hlau kos tuag, threaded hlau phaj, txias extrusion tuag, txias txiav txiab, voj saws, cov cuab yeej txheem, ntsuas cov cuab yeej, thiab lwm yam.
Cr12MoV steel yog high-carbon, high-molybdenum lysic steel. Nws cov ntsiab lus carbon tsawg dua li ntawm Crl2 steel, thiab nws tau ntxiv nrog molybdenum thiab vanadium cov ntsiab lus, uas txhim kho cov hlau thermal ua haujlwm zoo, cuam tshuam toughness thiab carbide tis. Cov hlau muaj siab hnav tsis kam, hardenability, hardenability, toughness, thermal stability, compressive zog, nrog rau micro deformation, zoo heev kev ua tau zoo thiab nws kim heev adaptability. Lub tshav kub softening yog 520 ℃. Qhov kev txiav tawm loj yog qis dua 4 hli thiab tuaj yeem ua tiav tag nrho. Qhov hnav tsis kam ntawm cov hlau no yog 3 ~ 4 npaug siab dua li cov hlau uas muaj zog tsawg, thiab qhov ntim ntim me me. Hardening qhov tob: roj quenching 200 ~ 300mm.
Thaum lub sij hawm crystallization txheej txheem, ib tug loj tus naj npawb ntawm eutectic dawb carbides yog tsim (cov carbonized tshuaj feem yog hais txog 20%, thiab eutectic kub yog hais txog 1150 ° C). Cov carbides no nyuaj heev thiab nkig. Txawm hais tias cov carbides tawg mus rau ib qho kev kawm tom qab billet dov, cov carbides tau muab faib rau hauv cov hlua, slabs, blocks, thiab pawg raws li cov kev taw qhia dov, thiab cov degree ntawm kev sib cais nce nrog txoj kab uas hla ntawm cov hlau.
