Stellite 12 Weartech WT-12 Stellite 12 Green Hard Facing Rod Green Color Cutter And Blade Outlet Valve Sealing Surface
Product Description
WL-Co12 could be considered an intermediate alloy between WL-Co6
and WL-Co1. It contains a higher fraction of hard, brittle carbides
than WL-Co6, and has increased resistance to lowangle erosion,
abrasion, and severe sliding wear whilst retaining reasonable
impact and cavitation resistance. WL-Co12 is often used self-mated
or running against WL-Co6 or WL-Co1. The higher tungsten content
provides better hightemperature properties compared to WL-Co6, and
it can be used at temperatures up to about 700˚C.
WL-Co12 is typically used for cutting tools that need to withstand
abrasion, heat and corrosion. Examples include industrial knives
for cutting carpets, plastics, paper and synthetic fibres; and saw
tips in the timber industry. It is also used for control plates in
the beverage industry, pump vanes, bearing bushes and narrowneck
glass mold plungers; and for hardfacing of engine valves, pinch
rollers in the metal-processing industries, and rotor blade edges.
