W9Mo3Cr4V Kev kub ceev steel zog:
W9Mo3Cr4V high-speed steel muaj superior toughness, hnav tsis kam, thiab thermoplastic zog piv rau W6Mo5Cr4V2, thaum nws hardness, liab hardness, thiab high-temperature hardness yog piv rau W6Mo5Cr4V2. Yog li ntawd, W9Mo3Cr4V high-speed steel tsis tsuas yog siv rau kev tsim ntau yam ntawm cov cuab yeej dav, tab sis kuj ua cov cuab yeej loj thiab thermoplastic tsim. Vim muaj lub zog siab thiab zoo hnav tsis kam ntawm W9Mo3Cr4V steel, nws kuj tuaj yeem siv los tsim cov khoom hnav tiv taus nyob rau hauv siab loads, xws li txias extrusion pwm. Txawm li cas los xij, nyob rau lub sijhawm no, quenching kub yuav tsum tau txo kom tsim nyog kom tau raws li qhov yuav tsum tau muaj zog thiab toughness. W9Mo3Cr4V kev kub ceev steel yog yooj yim rau oxidized thiab decarburized. Kev saib xyuas yuav tsum tau them rau nws thaum lub sijhawm ua haujlwm Kub thiab kev kho cua sov.
W9Mo3Cr4V steel, abbreviated li W9, yog tus sawv cev qib steel ntawm tungsten molybdenum series universal high-speed steel. Nws yog cov hlau alloy siab uas muaj ntau yam hlau alloy, thiab belongs rau Lystraite hom hlau. Nws muaj cov hardness siab, siab hnav tsis kam, siab thermal hardness, siab hardenability, txaus plasticity thiab toughness, thiab zoo casting, forging, vuam thiab machining zog, yog li nws occupies ib qho tseem ceeb txoj hauj lwm nyob rau hauv Tuam Tshoj.
