Stellite Alloy Nozzle Nplhaib

Cov qib zoo ntawm Stellite alloys yog: Stellite1, Stellite4, Stellite6, Stellite8, Stellite12, Stellite20, Stellite31, Stellite100, thiab lwm yam. Hauv kuv lub tebchaws, kev tshawb fawb ntawm Stellite kub alloys yog qhov tob thiab meej (cov tsev kawm tshawb fawb tseem ceeb hauv tsev thiab nce qib yog lub koom haum Iron thiab Steel Research thiab Beijing Rongpin Technology Co., Ltd., thiab lwm yam). Tsis zoo li lwm yam kub kub alloys, Stellite kub alloys tsis muaj zog los ntawm ib qho kev txiav txim nag lossis daus theem ruaj khov rau hauv matrix, tab sis los ntawm ib qho kev daws teeb meem ntxiv dag zog rau austenite fcc matrix thiab me me ntawm carbides faib rau hauv matrix. Casting Stellite siab kub alloys cia siab rau carbide ntxiv dag zog. Ntshiab cobalt crystals yog hexagonal kaw-packed (hcp) siv lead ua qauv hauv qab 417 degree, thiab hloov mus rau fcc ntawm qhov kub siab dua. Txhawm rau zam qhov kev hloov pauv ntawm Stellite kub alloys thaum siv, qhov tseeb tag nrho Stellite alloys yog alloyed nrog npib tsib xee kom stabilize tus qauv nyob rau hauv qhov kub ntawm chav tsev kub mus rau melting point. Stellite alloys muaj cov kev sib raug zoo ntawm kev ntxhov siab-kub, tab sis qhia tau hais tias kub corrosion kuj siab tshaj 1000 degree dua li lwm cov kub kub, tej zaum yog vim muaj cov ntsiab lus chromium siab, ib yam ntxwv ntawm hom alloy no.
