    Cobalt Base Alloy Valve Ball Seat

    Cobalt Based Alloy 20 Stellite 6 Valve Ball and Seat is made from is a hard alloy that can withstand various types of abrasion and corrosion as well as high temperature oxidation.

    The cobalt-base alloy was invented by American Elwood Hayness in 1907.
    The Stellite alloy has major component of cobalt, containing a considerable amount of nickel, chromium, tungsten and
    a small amount of molybdenum, niobium, tantalum, titanium, lanthanum, etc..Occasionally it contains an alloy of iron.
    According to the composition of the alloy, they can be made into wire, powder for hard surface surfacing, thermal spraying,
    spray welding, etc.. It also can be made into cast forging parts and powder metallurgy parts.
    We produce Stellite 6 Valve Balls with centrifugal cast process, investment process and resin sand cast process.

    Cobalt Base Alloy Valve Ball Seat Special Features:

    1.Good surface finish:SeatSeat

    2.We use Precision Cast Process to produce the Co alloy parts;

    3.We do heat treatment to achieve better wear performance.
