Stellite 3
Paub meej
Lub siab -zoo Stellite 3 (UNS R30003 / W.Nr. 2.4776) ua los ntawm Lork Group yog siab -carbon cobalt-chromium-tungsten hardfacing alloy uas muaj qhov tshwj xeeb hnav tsis kam thiab kub hardness.
Khoom Description
Lork Group siab-zoo Stellite 3 yog Cobalt-Chromium-Tungsten raws hardfacing alloy. Qhov kev sib xyaw ua ke ntawm cov khoom no ua rau muaj kev puas tsuaj loj heev, kub kub hardness thiab zoo corrosion kuj. Los ntawm casting lossis hmoov metallurgy Stellite 3 qhia txog qib hardness nyob rau hauv thaj tsam ntawm HRC 48-63. Stellite 3 yog siv nyob rau hauv ntau yam kev lag luam los ntawm kev siv lub tes tsho, lub rooj zaum valve, bearings bushings rau steel zeb qhia yob thiab hnav ntaub.
