Cobalt Base Alloy Seat
FANMETAL supply the Cobalt-Chromium Alloy Seat insert material Cobalt-Chromium Alloy 20 and Cobalt-Chromium Alloy 6 etc. We can supply the valve seat insert processed by the investment casting and powder metallurgy . Cobalt-Chromium Alloy 20 and Cobalt-Chromium Alloy 6 are good resistance performance to heat, corrostion wear and impact, used in steam and chemical valve seats and steam turbine bushing.
Cobalt-Chromium Alloy Seat and balls. Full processing is done on the valve ball and seat. The surface finish of the processed ball is Ra500 microinches. The dimensional tolerance is 0.0010 (0.0254 mm)。
Materials for ball valve seats-metal sealing materials
The metal sealing surface has high hardness and a suitable hardness difference. Surface hardening can be used to increase hardness and enhance wear resistance. Metal sealing materials mainly include chromium-based cemented carbide, cobalt-based cemented carbide, nickel alloy, tungsten carbide, stainless steel, etc.
