Molybdenum High Speed Steel yog dab tsi?
Molybdenum high speed steel yog hais txog ib hom kev kub ceev hlau tsis muaj tungsten cov ntsiab lus lossis nrog cov ntsiab lus tungsten tsawg dua li cov ntsiab lus molybdenum, uas yog cov khoom qis qis ntawm cov hlau refractory molybdenum, hu ua molybdenum high speed steel hauv lus Askiv, nrog cov ntsiab lus molybdenum ntawm 5 ~ 1. 0% thiab tungsten cov ntsiab lus ntawm 0 ~ 2%.
Feem ntau hais lus, qhov ceev thiab hardness ntawm molybdenum kev kub ceev hlau yog qis dua cov tungsten siab ceev hlau, feem ntau vim hais tias lub atomic hnyav ntawm molybdenum (96) tsuas yog atomic hnyav ntawm tungsten (184) feem ntau. Thaum cov khoom muaj pes tsawg leeg sib txawv, molybdenum high-speed steel kev ua tau zoo thiab kev siv sib txawv. Common molybdenum high-speed steel W2Mo9Cr4V2 steel thiab W2Mo9Cr4VCo8 steel.
W2Mo9Cr4V2 steel yog tsim los ntawm W cov ntsiab lus ntawm kwv yees li 2%, Mo cov ntsiab lus ntawm 9%, Cr cov ntsiab lus ntawm li 4% thiab V cov ntsiab lus ntawm 2% thiab lwm yam hlau ntsiab xws li high-speed steel, muaj qhov ntom me me, zoo dua. kub hardness, toughness thiab hnav tsis kam, zoo heev txiav zog thiab lwm yam ntxwv, feem ntau yog rau zus tau tej cov milling cutter, tshuab dhos, broach, molding cov cuab yeej, kais, saws, thiab txias-drawn tuag thiab hais txog.
