Tuag - casting steel
Kev siv rau aluminium alloy, tooj hlau alloy die casting pwm khoom xaiv yog 3 cr2w8v hlau, cov hlau alloying ntsiab uas muaj Cr, W, yuav ua rau qhov tseem ceeb kub thiab thermal nkau tsis haum, siab kub nrog txhua yam khoom zoo heev, ua haujlwm kub ntawm 650 ℃ cia cov thawj hardness uas tsim nyog casting hlau feem thiab puas ntsoog.Thaum ntawm chromium tau ua oxide zaj duab xis.Yog li ntawd, qhov sib ntxiv ntawm chromium tsis tsuas nce lub zog, tab sis tseem tiv thaiv cov hlau casting ntawm cov pwm ntawm lub pwm, yog li xws li los txhim kho nws txoj haujlwm thiab ua kom nws lub neej muaj kev pab ntau ntxiv.Qhov ntxiv ntawm cov vib nas this tau zoo dua thermal stability hauv high temperature dua, tab sis cov thermal conductivity thiab corrosion ntawm hlau tseem tsis tau raws li cov cai, yog tias yuav kom txo cov ntsiab lus los txhim kho qhov kev ua tau zoo thiab cuam tshuam cov hnyav ntawm hlau thiab lub zog, yog li koj tuaj yeem los ntawm cov tshuaj tua hluavtaws, xws li qis tsis txaus qhov oxidation, cov pa roj carbon dioxide nitriding ntu infiltration ntawm C-N formation alloy nitride txheej, yuav tiv thaiv casting hlau tsev nyob hauv cov kab noj hniav kom nws qhov chaw kaj thiab huv, zoo dua thermal conductivity thiab corrosion resistant.Thiab tas, qhov compressive nyuab xeev nyob rau hauv oxide txheej tau txhim kho nws lub dag lub zog thiab ncua sij hawm tawg, thiaj li ua rau cov tsis muaj peev xwm ntawm cov hlau.Nws tuaj yeem txhim kho cov hluav taws xob cov hluav taws xob thiab corrosion tsis ua hauj lwm ntawm lub pwm thiab tiv thaiv cov hlau ntawm so.
