Stellite 1

Paub meej

Khoom Description

Lork Group siab-zoo Stellite 1 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 heev corrosion kuj. Los ntawm casting los yog hardfacing deposition Stellite 1 qhia hardness theem nyob rau hauv ntau yam ntawm HRC 50-58. Stellite 1 yog siv nyob rau hauv ntau yam kev lag luam los ntawm kev siv hauv lub tes tsho twj tso kua mis, lub nplhaib sib txuas, hnav cov ntaub qhwv, lub tes tsho bearing mus rau qhov kub thiab txias valve sealing nto.
